Any publication based on the data should acknowledge the National Center for Health Statistics (NCHS) as the original source.It should include a disclaimer which credits the authors for any analyses, interpretations, or conclusions, and not NCHS, which is responsible only for the data. 2. Consumers who wish to publish a technical description of the data should make a reasonable effort to ensure that the description is not inconsistent with that published by NCHS.This does not mean, however, that NCHS will review such descriptions. 3. The National Center for Health Statistics would appreciate receiving reprints of journal articles or other publications based upon find- ings from the NHANES II survey. Please forward copies to: Division of Health Examination Statistics National Center for Health Statistics Center Building, Room 2-58, 3700 East-West Highway Hyattsville, Maryland 20782 Editing of the Data Sets The data users' tapes have been subjected to a great deal of careful editing. Some of the continuous data items have extremely high or low values and it has been verified that they do in fact appear that way on the original inter- view documents; that is, it has been verified that the values have not been incorrectly keyed.Within each data tape numerous consistency checks have been performed. However, due to the large volume of data collected in the survey, it is likely that a small number of errors or discrepancies remain undetected . The Division of Health Examination Statistics, NCHS would appreciate if any such errors are detected that they be brought to our attention so that errata sheets can be issued to previous purchasers and corrections made if new data tapes are created. BACKGROUND Description of Survey Description of Survey: A detailed description of the design, content,ques- tionnaires, and operation of NHANES II is provided in the following report: Plan and Operation of the Second Health and Nutrition Examination Survey, 1976-1980, DHHS Pub. No. (PHS) 81-1317 Series 1, No. 15, Public Health Service, Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402. The stock number is 017-022-00752-5 and the cost is $5.50. One copy is provided with the documentation herein, and a general summary of the data collection techniques and content is given in Appendix A. DESCRIPTION OF POPULATION Target Population:NHANES II was conducted on a nationwide probability sample of approximately 28,000 persons, ages 6 months-74 years, from the civilian, noninstitutionalized population of the United States. The survey started in February 1976 and was completed in February 1980. The NHANES II sample was selected so that certain population groups thought to be at high risk of malnutrition (persons with low incomes, preschool children and the elderly) were oversampled. Adjusted sampling weights were then computed for 76 age, sex,and race categories in order to inflate the sample in such a manner as to closely reflect the estimated civilian noninstitutionalized U.S. population ages 6 months-74 years at the midpoint of the survey (March 1, 1978). METHODS Use of Sample Weights NHANES II uses a multistage sample designed to represent the civilian noninstitutionalized population of the United States,6 months-74 years of age . Since the sample is not a simple random one, it is necessary to incorporate the person's sample weight for proper analysis of the data.The sample weight is a composite of the individual selection probability, adjustments for nonresponese, and poststratification adjustments. NHANES II provides information on 20,322 interviewed and examined individuals . In addition to the general examination components, several more detailed examinations were performed on subsamples of the population. Therefore, instead of there being one sample weight per person,there are several sample weights for each person. If a person was not selected for a particular subsample, their associated subsample weight is zero. When analyzing the special subsamples, the analyst must be careful to select the appropriate sampling weight from the weights found in tape locations 282-317. For a more complete description of how the sample weights are calculated, see the detailed note section of this documentation. Sample Design, Variance Estimation, and Hypothesis Testing The data collected in the Second National Health and Nutrition Examination Survey (NHANES II) were obtained through a complex sample design involving both clustering and stratification.Because of the complex design and the ratio adjustments applied to the sample weights (see previous section on use of sample weights), the direct application of standard statistical analysis methods for variance estimation and hypothesis testing may be very misleading .The modification of statistical analysis procedures to incorporate the effects of complex survey designs is an important area of research;however, the current methodologies appropriate for the analysis of data from such surveys have not been made readily available in the standard packaged statistical software. There are computer programs available which do provide the capability of variance estimation for complex sample designs. The balanced repeated replication approach 1/ is utilized in &REPERR-&PSALMS-OSIRIS.IV 2/ to calculate the variance-covariance matrix.SESUDAAN, SURREGR 3/ and SUPERCARP 4/ are programs that calculate the variance-covariance matrix using the linearization approach 5/ (Taylor series expansion). In order to provide the user with the capability of estimating the complex sample variances in the NHANES II data using the above procedures, we have provided Strata and Pseudo Primary Sampling Unit (PSU) codes on all data tapes in positions 324-326. These variables and the sample weights are necessary for the calculation of variances. Even though the overall number of examined persons in this survey is quite large for statistical inference purposes, subclass analyses can lead to estimaters that are unstable, particularly estimates of variances. Consequently, analyses of subclasses require that the user pay particular attention to the coefficient of variation for the estimates of means, proportions and totals.In addition, small sample sizes, or a small number of PSU's used in the variance calculations may produce unstable estimates of the variances using the above computer programs. An NCHS Series 2 publication discussing these issues is in publication.6/ DEMOGRAPHIC INFORMATION, NHANES II Demographic Information An advance letter, announcing the forthcoming arrival of an interviewer from the U.S.Bureau of the Census,was mailed to each household that fell into the NHANES II probability sample. The interviewer subsequently visited the household to ascertain its composition and to administer a questionnaire,the primary purpose of which was to obtain demographic information. The questionnaire was administered to each potential sample person in each household that was available and competent enough to respond to questions.In the event that a potential sample person was not at home at the time of interview, any responsible adult in the household was asked to respond to the questions for the absent person.

According to the definition used in the 1970 census, the urban population was comprised of all persons living in (a) places of 2,500 inhabitants or more incorporated as cities, boroughs (except Alaska),villages and towns (except towns in New York ,New England States,and Wisconsin),but excluding those persons living in the rural portions of extended cities; (b) unincorporated places of 2,500 inhabitants or more; and (c) other territories included in urbanized areas. the remaining population was classified as rural. Urban areas are further classified by population size for places within urbanized areas and other places outside urbanized areas. Tape Position 12 - SMSA Except in New England,a standard metropolitan statistical area is basically a county or a group of contiguous counties which contains at least one city of 50,000 inhabitants or more, or "twin cities" with a combined population of at least 50,000. In addition to the county or counties containing such a city or cities, contiguous counties are included in an SMSA if, according to the 1970 census, they are socially and economically integrated with the central city. Each SMSA must include at least one central city,and the complete title of an SMSA identifies the central city or cities. In New England, SMSA's consist of towns and cities, rather than counties.

For this survey purpose, the principal job or business of a respondent is defined in one of the following ways: If the person worked during the two-week interview period or had a job or business, the question concerning his occupation (or work) applies to his job during that period.If the respondent held more than one job, the question is directed to the one at which he spent the most time. It refers to the one he considers most important when equal time is spent at each job. A person who has not begun work at a new job, is looking for work, or is on layoff from work is questioned about his last full-time civilian job.A full-time job is defined as one at which the person spent 35 or more hours per week and which lasted two consecutive weeks or more. A person who has a job to which he has not yet reported and has never had a previous job or business is classified as a "new worker".

No effort was made to reconcile amounts reported in detailed questions 21 and 22 with the categorical response to the family income group question. During the survey time period, no adjustments to the income groups or $7,000 value were made to account for inflation.

Those regions, which deviate somewhat from the groups used by the Bureau of Census, are as follows: Region States Included Northeast Maine, Vermont, New Hampshire, Massachusetts, Connecticut, Rhode Island, New York, New Jersey, and Pennsylvania South Delaware, Maryland, District of Columbia, West Virginia, Virginia, Kentucky, Tennessee, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and Arkansas Midwest Ohio, Illinois, Indiana, Michigan, Wisconsin, Minnesota, Iowa, Missouri West Washington, Oregon, California, Nevada, New Mexico, Arizona, Texas, Oklahoma, Kansas, Nebraska, North Dakota, South Dakota, Idaho, Utah, Colorado, Montana, Wyoming, Alaska, Hawaii Tape Positions 210-212 - Poverty Index Income status was determined by the Poverty Income Ratio (PIR). Poverty statistics published in the Census Bureau reports 1-5 were based on the poverty index developed by the Social Security Administration (SSA) in 1964. (For a detailed discussion of the SSA poverty standards, see reference 6.) Modifications in the definition of poverty were adopted in 1969.7 The stand- ard data series in poverty for statistical use by all executive departments and establishments has been established.8 The two components of the PIR are the total income of the household (numera- tors the median of the income group for incomes $7,000 and above; the sum of the porponent parts of the income questions for incomes under $7,000) and a multiple of the total income necessary to maintain a family with given characteristics on a nutritionally adequate food plan3 (denominator). The dollar value of the denominator of the PIR is constructed from a food plan (economy plan) necessary to maintain minimum recommended daily nutritional requirements.The economy plan is designated by the Department of Agriculture for "emergency or temporary use when funds are low." For families of three or more persons,the poverty level was set at three times the cost of the economy food plan.For smaller families and persons living alone,the cost of the economy food plan was adjusted by the relatively higher fixed expenses of these smaller households. The denominator or poverty income cutoff adjusts the family poverty income maintenance requirements by the family size, the sex of the family head, the age of the family head in families with one or two members, and the place of residence (farm, nonfarm).Annual revisions of the poverty income cutoffs are based on the changes in the average cost of living as reflected in the Consumer Price Index. As shown in the tables, the annual income considered to be the poverty level increases as the family size increases. A family with any combination of characteristics and with the same income as shown in the table has been designated as having a PIR or poverty level of 1.0. The same family with twice the income found in the table would have a PIR of 2.0. Ratios of less than 1.0 can be described as "below poverty",ratios greater than or equal to 1.0, as "at or above poverty". Poverty thresholds are computed on a national basis only. No attempt has been made to adjust these thresholds for regional,state,or other variations in the cost of living (except for the farm, nonfarm difference).None of the noncash public welfare benefits such as food stamp bonuses are included in the income of the low income families receiving these benefits.PIR has been adjusted by year (see tables) and accounts in some part for inflation. 1 U.S. Bureau of the Census, Current Population Reports, Series P-60, No. 107, "Money Income and Poverty Status of Families and Persons in the United States: 1976" (Advance Report) U.S. Government Printing Office, Washington, D.C., 1977. 2 U.S. Bureau of the Census, Current Population Reports, Series P-60, No. 116, "Money Income and Poverty Status of Families and Persons in the United States: 1977" (Advance Report) U.S. Government Printing Office, Washington, D.C., 1978. 3 U.S. Bureau of the Census, Current Population Reports, Series P-60, No. 120, "Money Income and Poverty Status of Families and Persons in the United States: 1978" (Advance Report), U.S. Government Printing Office, Washington, D.C., 1979. 4 U.S. Bureau of the Census, Current Population Reports, Series P-60, No. 125, "Money Income and Poverty Status of Families and Persons in the United States: 1979" (Advance Report), U.S. Government Printing Office, Washington, D.C., 1980. 5 U.S. Bureau of the Census, Current Population Reports, Series P-60, No. 127, "MoneyIncome and Poverty Status of Families and Persons in the United States: 1980"(Advance Data from the March 1981 Current Population Survey), U.S. Government Printing Office, Washington, D.C., 1981. 6 Orshansky, M.: "Counting the Poor: Another Look at the Poverty Profile", Social Security Bulletin, January 1965; "Who's Who Among the Poor: A demographic View of Poverty", Social Security Bulletin, July 1965. 7 U.S. Bureau of the Census, Current Population Reports, Series P-23, No. 28 "Special Studies", U.S. Government Printing Office, Washington, D.C., August 12, 1969. 8 Circular No. A-46,Transmitted Memorandum No. 9,Executive Office of the President, Bureau of the Budget, August 29, 1969, and Exhibit L (rev.). Tape Positions 282-323 A multistage estimation procedure was used to calculate the various NHANES II subsample sample weights that are necessary to use in any analysis of the data.The procedure has three basic components:(1) inflation by reciprocals of the probabilities of selection, (2) adjustment for nonresponse, and (3) poststratification ratio adjustment by age-sex-race. A brief description of each component is as follows: Inflation by reciprocals of the sampling probabilities.Since the survey utilized a three-stage sample design, there were three probabilities of selection: (1) the probability of selecting the PSU,(2) the probability of selecting a segment (housing unit),and (3) the probability of select- ing a sample person. Adjustment for nonresponse. Estimates from the NHANES II data were adjusted to account for sample persons who were not examined. The estimates were inflated by a multiplication factor calculated within five selected income groups, three age groups, four regions, and standard metropolitan statistical area (SMSA) or non-SMSA. The numerator of these factors was the sum of the weights for sample persons resulting from the reciprocal of the probability of selection, and the denominator was the sum of the weights for examined persons also resulting from the reciprocals of the sampling probabilities. Poststratification by age-sex-race. The estimates were ratio adjusted within each of 76 age-sex-race cells to an independent estimate,provided by the U.S. Bureau of the Census, of the population of each cell as of March 1, 1978, (approximate mid-point of the survey). The ratio adjustment was a multiplication factor of which the numerator was the U.S.population and the denominator was the sum of the weights adjusted for nonresponse for examined persons. This ratio estimation process makes the sample more closely representative of the civilian, noninstitutionalized population of the U.S. Potential bias of nonresponse.Usually a sizeable number of sample persons who initially are willing to complete the household information and some of the medical history questionnaire subsequently will not participate in the examination.This creates the potential for bias if these persons differ from other sample persons with respect to the variables being studied. Intense efforts were undertaken during NHANES II to develop and implement standard procedures and inducements that would reduce the number of nonrespondents and thereby reduce the potential for bias. The user needs to be aware of and should explore the potential bias for nonresponse in any analysis of the NHANES II data. Tables (By Size of Family, Sex of Head, Farm-Nonfarm Residence) Table 15.

AUDIOMETRIC AIR CONDUCTION TEST INFORMATION, AGES 4-19 YEARS Data Set Description This data tape contains demographic, and audiometric data for persons 4-19 years old who were both interviewed and examined in the second National Health and Nutrition Examination Survey (NHANES II). Description of Audiometric Tests Each child or youth 4-19 years old was tested at the following four frequencies: 500, 1000, 2000, and 4000 Hertz (Hz), with the 1000 Hz frequency repeated a second time as a measure of the reliability of test results. Hearing threshold level, as defined here, is the lowest intensity of a pure tone produced in the audiometer earphone that is just audible to the ear of the examinee in a specified number of trials. The standard audiometers used in the survey were calibrated in accordance with the 1969 American National Standards Institute (ANSI) specifications. Hence the zero sound intensity level on the dial of these instruments correspondents to the 1969 ANSI reference zero. Alternation of presentation to each ear was varied among examinees to safeguard against bias in testing. The threshold recorded for each frequency was the lowest decibel (dB) level at which 50 percent or more of the responses were obtained, that is, in two out of three or three out of five trials. Masking for the nontest ear was done in air conduction testing only on retest when there was a 40 dB difference or more in the thresholds for the two ears. The effective range of audiometric testing was 0 to 100 dB. Hearing threshold levels of 100 dB or more were coded "99." Hearing threshold data obtained at 0 dB to - 20 dB have been grouped at 0 dB in order to avoid reporting spurious findings due to nonlinearity of the hearing level attenuators of the six audiometers. Hearing threshold data reported at 0 dB to 10 dB must be considered with caution as the linearity of the hearing level attenuators on several of the six audiometers was found to vary beyond acceptable tolerance limits. Standardized testing procedures were used to insure as consistent test results as possible throughout the survey. Any condition such as earache, cold, or other problem that might affect the test results was also recorded. Caution Reuse of Statistical Summary Measures The data user is cautioned that statistical summary measures such as the mean, standard deviation and standard error will reflect the truncation of the distribution of pure-tone air conduction hearing levels at 0 dB and + 100 dB and nonlinearity at 0 dB to 10 dB. Estimated percentiles at the median and above should be relatively free of the effects of distribution truncation and of measurement bias. With these caveats in mind, these data provide data users with the opportunity to examine for themselves a large set of audiometric measurements made in a standardized manner on a representative sample of the 4-19 year old segment of the U.S. population. Medical History and Related Data Collection and Examinations Medical history data obtained in the household are available on other public use tapes available from NTIS (Catalog Numbers 5010 and 5020). Those tapes contain data on hearing and speech problems in addition to other medical history information. Tape Catalog Number 5010 contains data for children 3-11 years of age on running ear, ear infection, deafness, or trouble hearing (including age at onset), rating of hearing by ear, surgery on ears, hearing aid use, hearing testing, speech problems, speech therapy, relatives with hearing or speech problems, age when spoke first word, age when started to use sentences, and other language spoken. Tape Catalog Number 5020 contains data for persons 12-74 years old on ringing or funny noises in ears, running ear, ear infection, deafness, or trouble hearing (including age at onset), causes of hearing trouble, rating of hearing by ear, surgery on ears, hearing tested, hearing aid use and, for those at least 17 years old, job history related to noise level. Additional hearing and speech related data were also collected in the examination portion of the survey. A speech pathology test involved the use of a tape recording of the subject's repetition of specially developed sentences. It was carried out on examined persons between the ages of 4 and 6 years, permitting interpretations as an indication of problems with articulation and language development. A comprehensive examination of the ear, nose, and throat (ENT) during the physical examination was performed by a physician on persons 6 months through 74 years. The examination included an inspection of the external ears, auditory canals, tympanic membranes, anterior nasal cavity, and oral pharynx. Data Editing Preliminary editing of the interview forms was done by personnel of NCHS. They verified and corrected, to the extent possible, problematic data and did further edits for consistency, completeness, and accuracy of the data against microfilm records of the original questionnaire where needed.

Persons who had hearing threshold levels of 0 dB or less were coded "00." Tape Position 480 - Dummy Record The term "Dummy Record" refers to a tape record for a respondent who was included in the sample but for whom no Audiometric Air Conduction Test was done. Although demographic data are available for all respondents, positions 409-475 are all blank in dummy records, and position 480 contains a code of "1" to identify such records. If position 480 contains the code "blank", at least some Audiometric Air Conduction Test data were received for that respondent. REFERENCES 1.

Vital and Health Statistics, Series 2. (In publication) APPENDIX A - DATA COLLECTION TECHNIQUES AND CONTENT The plan developed with respect to the content of NHANES II called for the following: A. Questionnaires completed in the household: (1) Household questionnaire: For each household member, questions referred to family relationships;certain demographic items such as age, sex, and race; selected housing information;occupation, income, education, veteran status; and an indication of participation in food stamp programs. (2) Medical history questionnaires: (a) For each sample person ages 6 months-11 years The questionnaire included items on birth weight, prematurity,congenital conditions, medication, neurological conditions, lead poisoning, accidents, hospital care, disability, diarrhea, pica, vision, and a variety of chronic conditions. In addition, data were collected on allergies, kidney and bladder disease, anemia, speech and hearing, lung and chest conditions, and participation in food programs. (b) For each sample person ages 12-74 years The questionnaire included items on medication; hospital care; tuberculosis; a variety of acute and chronic diseases; tobacco usage, physical activity; weight; height; vision disability, exposure to pesticides; gastrointestinal problems; and for females; a menstrual and pregnancy history. In addition, data were collected on anemia, diabetes, respiratory condition, hearing and speech, liver and gallbladder conditions, kidney and bladder disease, allergies, hypertension, cardiovascular conditions, stroke, arthritis (stressing middle and upper back and neck problems), and participation in food programs. Questionnaires and tests administered in the mobile examination center: (3) Dietary Questionnaires (a) For each examined person, a 24-Hour Recall was administered by trained dietary interviewers. Specific and quantitative detail of every food or drink consumed during the previous day was recorded and calculated, thus providing estimates of calories, protein, carbohydrates, fat, unsaturated fats, cholesterol, and specific vitamins and minerals consumed. (b) For each examined person, a Food Frequency interview was administered to ascertain usual patterns of food consumption. Daily and/or weekly consumption of foods within 26 subgroups were recorded. In addition, data were collected on usual vitamin-mineral supplement usage. (c) For each person ages 12-74 years, a Dietary Supplement form was self-administered and reviewed. This form provided information on special diets, recent medications and barriers to purchasing groceries or eating foods; it does not provide information on vitamin/mineral or other supplements to the diet. (4) Medication/Vitamin Usage Form provided information on the past week's usage of any medicines; vitamins or minerals for al examined persons. (5) Behavior Questionnaire elicited data on behavior which may be associated with coronary heart disease for examined persons ages 25-74. B. Examination by physician A physician performed and recorded the results of a medical examination giving special attention to specified findings related to nutrition, to hearing, to the thyroid gland,and to the cardiovascular, respiratory, neurological and musculoskeletal systems. C. Special clinical procedures and tests A specially trained health technician carried out the following on examined persons in the designated age ranges: 1. Spirometry trials of examined persons ages 6-24 years, were digitized and recorded on magnetic tape. Various pulmonary function indicators such as FVC (forced vital capacity), FEV1 (forced expiratory volume in one second), and peak flow rate were subsequently derived from these data. 2. Electrocardiograms Electrocardiographic signals of examined persons ages 25-74 years were digitized and recorded on magnetic tape providing normative data of amplitude, duration, interval and axis measurements and permitting interpretations of heart disease according to the Minnesota classification code. 3. Body Measurements were made on all examinees and included standing height, body weight, triceps and subscapular skinfolds, and several other anthropometric measurements. 4. Puretone audiometry Tests were carried out on examined persons between the ages of 4 and 19 years, permitting determination of threshold levels of hearing for frequencies of 500, 1000, 2000, and 4000 Hertz for right and left ears. 5. Speech recording, involving use of tape recording of the subject's repetition of specially developed sentences,was carried out on examined persons between the ages of 4 and 6 years, permitting interpretations as an indication of problems with articulation and language development. 6. Allergy tests, involving skin tests (prick test) with eight common allergens (housedust, alternaria, cat fur, dog fur, ragweed, oak, rye grass, and Bermuda grass).The tests were made on examined persons between the ages of 6 and 74 years, to obtain degrees of skin reaction. D. X-Rays For examined persons ages 25-74 years, two x-rays were made. No x-rays were taken of pregnant women and no lumbar x-rays were taken on women under 50 years of age. 1. X-ray of cervical and lumbar spine, were taken to provide evidence of osteoarthritis and degenerative disc disease, and 2. X-ray of chest, to be used in the diagnosis of respiratory diseases and to serve as a measure of left ventricular enlargement. E. Urine tests Tests as follows were performed on casual samples of urine: 1. N-Multistix tests for qualitative protein, glucose, ketones, bilirubin, blood, urobilinogen, pH, and bacteriuria (nitrite test) were done for examined persons ages 6-74 years. 2. Urinary sediments, including red cells, white cells, and casts, were measured for a subsample of examined adults ages 20-74 years. 3. Gonorrhea cultures, of urinary sediments were performed for male and female examined persons ages 12-40 years. However, of those females who received the Glucose Tolerance Test (GTT) only those ages 20-24 years had the gonorrhea test performed. 4. Analyses for pesticide residue and metabolite levels,were carried out on a subsample of examined persons ages 12-74 years, including measures of the body burdens from exposure to alkyl phosphate residues and metabolites, carbamate residues, phenolic compound residues and malathion metabolites. F. Tests on blood samples Samples of blood provide a broad range of information related to health and nutrition. The particular tests performed varied with the specific target condition and age group as described in the Series 1, No.15 program description (page 39). 1. Glucose tolerance test (GTT) This test involved collection of blood specimens while in a fasting state, as well as at one and two hours after glucose challenge. The test was performed on a specified subsample of examined adults to provide estimates of the prevalence of diabetes. 2. Tests related to liver function (a) Post-prandial liver bile acid test. This test measures the ability of the liver to remove bile acids from the blood following consumption of a food preparation which induces eventual addition of bile acids to the blood via contraction of the gallbladder. (b) Liver biochemistries performed include bilirubin, SGOT, and alkaline phosphatase tests. 3. Anemia-related laboratory tests The tests made to characterize anemia consisted of protoporphyrin,iron,total iron binding capacity (TIBC), zinc, copper, red cell folates, serum folates, serum ferritin, B12, and the determination of abnormal hemoglobin. 4. Other nutritional biochemistries These tests include albumin,Vitamin A and Vitamin C. 5. Serum lipids Because of their important relevance to cardiovascular disease, determinations were made of cholesterol, triglycerides, and high density lipoprotein (HDL). 6. Biochemistries for body burden from environmental exposures Determinations were made of body burden levels of lead and pesticide residues and metabolites.Tests were also performed for carboxyhemoglobin which reflects environmental exposure to carbon monoxide and the individual's smoking habits. 7. Hematology The hematology included determinations of hemoglobin, hematocrit,red blood cell count,white blood cell count and differential leukocyte analysis, and red blood cell morphology and hemoglobin phenotyping. 8. Kidney function The only quantitative test for kidney function performed on blood samples was the serum creatinine test. 9. Syphilis The serology determinations for syphilis included qualitative and quantitative ART, a FTA-ABS and MHA-TP. APPENDIX B - AUDIOMETRY SCREENING EXAMINATION PROCEDURES Equipment Soundproof room.

Attach connector labeled "amp. input" into channel I output of microphone power supply. d. Insert cable from 1/2" microphone into channel I input of microphone power supply. e. Connect 1/2" microphone to cable. f. Pull up black knob below indicating meter to turn the power on. Check to see that the power indicator light is flashing. g. Turn the same black knob to "Batt." position. If meter pointer falls within section marked "battery," the batteries are satisfactory for use. Otherwise, replace batteries per instrument instruction manual. Daily Field Checks - Audiometer Turn power on and switch to manual mode. Turn tone switch to "on" position to turn on the tone indicator light. 1. To check tone quality: a. Set hearing level dial at 40 dB. b. Turn channel I output control alternatively to left and right phones. c. Turn frequency dial successively from 500 Hz through 4000Hz while listening through each earphone in turn for purity of tones. d. Check appropriate spaces on the form and note any abnormalities. 2. To check the hearing level control: a. Set the Frequency dial on 2000 Hz. b. Turn the hearing level dial slowly from 20 to 60 dB and back to zero while listening for scratches, abrupt changes in loudness of tone, or for other extraneous signals. c. Check appropriate spaces on the form as each phone is checked and note any abnormal conditions in the "Remarks" section. 3. To check the wires leading to the earphones: a. While wearing the earphones and with the 1000 Hz tone on at 40 dB, shake the wire to each earphone gently and listen for scratches, interruption of the tone, or any other abnormality. b. If the tone is interrupted or changes loudness, tighten the set screws holding the earphone cord in the earphone. If this action does not correct the fault, replace the audiometer. c. It may be necessary to replace an earphone cord from time to time. This can be done by loosening the set screws in the earphone, unplugging the old earphone cord, plugging in the new cord, and finally tightening up the set screws. 4. The attenuator and frequency dials may slip on the shaft. If this happens, report it under "Remarks" and replace the audiometer. 5. Send any defective unit to EAR-CO for service. If neither audiometer works properly, contact Mr. Kenneth Stewart for instruction. Equipment Care The only care the Revox recorder and language master equipment needs on a regular basis is to keep the tape path clean. This is very important because the machine will perform its best only if all parts of the tape path are clean. A soft cotton or linen cloth is most suitable for cleaning. If necessary the cloth may be moistened with a little alcohol. Hand instruments must not be used for cleaning the tape path under any circumstances. The heads should be cleaned carefully. The capstan and pressure roller should be cleaned with a dry cloth. The recorder must never be oiled. At the beginning of the stand the Revox recorder and language master must be degaussed. 1. Procedure for Degaussing. a. Remove all ecorded material from room so as not to destroy or damage the recordings. b. Hold the degausser 3 ft. away from the head while energizing it. c. Slowly move the degausser towards the heads. Move the tip around the head, capstan, and other metal parts in the tape path. d. Slowly move the degausser away from the machine until it is 3 ft. away. At this point, deenergize. e. WARNING. Do not leave the degausser energized for more than 4 minutes. Otherwise it will overheat and self destruct. f. The degausser doesn't need to touch the head to degauss it. It just has to be close to it. Field Calibration General a. Field calibration of both audiometers will be performed at the start of each stand, weekly during the examination period, and at the end of each stand. b. The field calibration report forms give the expected reading at each frequency and the tolerance limits allowed around that reading. The expected readings were determined for each set of field calibration equipment at EAR-CO's laboratory. If a microphone requires replacement, the calibration equipment is to go back to EAR-CO for a determination of new expected readings for the new microphone. c. Reports on these field calibrations are to be made in duplicate. One copy is to be mailed that day to Miss Jean Roberts and the other to EAR-CO. d. If the calibration shows a unit to exceed the specified limits, an independent calibration is to be made by another technician. If both technicians then agree that the audiometer is in calibration, the unit will be considered for use. If the difficulty cannot be resolved, the unit is to be sent to EAR-CO for service. Pure Tone Calibration a. To prepare the sound level meter for use: (1) Screw the artificial ear coupler onto the meter case. (2) Unscrew the top half of the coupler. (3) Screw the microphone cartridge (1" diameter) with protective grid onto the bottom half of the coupler. (4) Turn the black knob above the meter to position the number 90 opposite the marker on the meter case. Turn the clear knob to place the red circle over the number 90. (5) Set the functin selector to A-Slow. (6) Remove the 1/2" adapter from the acoustic calibrator and set the calibrator firmly over the microphone. (7) Press the tone actuator (on side of calibrator) once and release. (8) The sound level meter should read 94 dB on the A scale. If not, use a screw driver (supplied with meter) to turn the adjustment screw to produce the desired reading. (If the tone has disappeared, press actuator again to bring the tone back on.) The sound level meter is now in calibration. b. To mount the earphone: (1) Remove the protective grid from the microphone cartridge and screw the adapter ring onto the cartridge. Take great care not to touch the microphone diaphragm. (2) Screw the top of the coupler back on and remove the capillary pin contained therein. (3) Set the earphone to be tested over the cavity of the coupler, making sure that the earphone rests squarely on the coupler. (4) Place the 500 gram weight on top of the earphone and reinsert the capillary pin. c. Calibration procedure: (1) Turn the black knob on the sound level meter until the number 70 on the dial is opposite the marker on the meter case and keep the red circle over 70. (2) Set the audiometer to a frequency of 500 Hz and 70 dB hearing level. (3) Turn the tone switch to "on." (4) Select the earphone under test. (5) Record the sound level meter reading (A-scale) on the report form. Example: The meter reading is determined as follows: Red Circle over 70 Meter needle at 6.5 Meter reading is 76.5 dB Since the expected reading at this frequency is 76.8 dB with a tolerance of +4 dB, the audiometer is within calibration at this frequency. (6) Continue testing at the other three frequencies indicated in the report form. In each case the report form provides the appropriate settings for the sound level meter. (7) To test the other earphone: Remove the weight and lift the earphone already tested off the coupler. Remove the capillary pin. Place the other phone and weight back on and reinsert capillary pin. Repeat steps (2) through (6). Masking noise calibration a. Set up the field calibration equipment as before. b. Set function selector on the B & K meter to "C-Slow" position. c. Turn the audiometer channel II tone switch to "on" to bring tone indicator light on. Turn the channel I tone switch "off." d. Turn the Freq. and Input dial to "N. B. Noise" and channel I frequency selector to 500 Hz. e. Set the masking level knob at 60 dB as indicated on the form. f. Select the earphone under test. g. Set the black knob and red circle on the sound level meter at 80 and obtain the reading. Example: The actual masking signal level at the selected range of frequencies is determined as follows: Red Circle over 80 Meter needle at 2.4 Masking signal level is 82.4 dB Since the expected reading is 81.7 dB with a tolerance of +4dB, the level of the masking noise is within the specifications in this frequency range. h. Repeat the procedure with the channel I frequency selector at other frequencies and other attenuator settings indicated on the form. Environmental Noise Survey A noise survey is to be done during the setup day before the start of each stand of examination. One copy of the completed form should be sent immediately to Miss Roberts and one to EAR-CO. Adhere to the following procedures. 1. Screw the 1" microphone (with protective grid in place) directly onto the connector on the B and K sound level meter. 2. Check the battery condition and calibration per previous instructions. 3. Set the selector knob to "Ext. Filt. Slow" position. 4. Set weighting switch on the octave filter set to "off." 5. Close both doors to the audiometer room. 6. Turn off all hearing test equipment. 7. Set the black knob to 70. 8. Rotate the frequency knob to 31.5. 9. Adjust the red circle knob to obtain a meter reading which is somewhat above 0 dB on the meter scale. Read the red circle number and add to it the meter reading. Example: Red Circle on 60 db Meter reading 4 db Environmental noise level 64 db at 31.5 Hz 10. Record the reading on the appropriate form. NOTE: The meter reading will fluctuate considerably. Try to estimate an average reading after having observed the meter for a moment. 11. Turn the frequency knob to 63. 12. Turn the red circle knob to obtain a meter reading as in instruction 9. 13. Proceed through each octave band 125 Hz ... 8,000 Hz. 14. Under "Comments" explain circumstances, if possible, where the environmental noise levels exceed ANSI allowable levels. Audiometric Testing Procedures General At the beginning of each examination session turn on the audiometer at least 10 minutes before performing the daily field check. At the completion of testing, perform a second field check. Both doors to the audiometric room should be closed while testing. a. Recording Use the left side of form first when the sample number is even and the right side first when the sample number is odd. Enter the beginning time, audiometer number, and technician number on control record. Indicate which ear will be tested first by circling right ear or left ear on the form. This will check for any bias. b. Audiometric testing Perform air condition tests for both ears in the sequence indicated on the recording form. If any part of the test cannot be completed, enter "X" in the appropriate space and indicate the reason under "Condition Affecting Test Results." If other than physical conditions of the examinee have affected any of the audiometric results, explain in the space provided at the right of this section. If any thresholds of 30 dB or greater are obtained, be sure to question the examinee about physical conditions which might contribute to the results and check the appropriate box or boxes under "Condition Affecting Test Results." For a 15 to 19 year old with a 40 dB or greater threshold at 4000 Hz in one or both ears, ask if he has listened to a large amount of amplified music. Please note under number 8 "Other." If the examinee does not respond to 100 dB at any test frequency, record "100+" in the appropriate space. c. Instructions to examinee Detailed instructions should be given the examinee to stress the following points: * Once the earphones are placed by the technician, they must not be touched by the examinee. The technician should ask if they are comfortable and readjust if necessary. *Tell the examinee that he will hear tones that are high and low and will become softer and softer until he will have difficulty hearing them. When he hears the tones, he should depress the response button and release it when the tone is no longer heard. Remind him to concentrate very hard when the tones are soft. * Eyeglasses, earrings, chewing gum, wigs, and hair ornaments should be removed if they interfere with proper placement of the headset. (1) Example of verbal instructions for 7 to 19 year olds. (a) We are going to see how well you hear some tones from these earphones. (b) You will hear short tones that are both high and low. They will become softer and softer. (c) Each time you hear a tone, please press this button (technician demonstrates with response button) and when you no longer hear the tone let the button up. (d) Listen carefully when the tone starts to get softer but even if you think you hear it, press the button and I will be able to tell if you hear it. (e) First you will hear the tones in your right/left ear (point) and then in your other ear. (f) If the tone seems to be in this ear (point to nontest ear), please tell me. (g) Remember to press the button when you hear a tone and let it up when you no longer hear it. (h) Do you have any questions? (If so, clarify as necessary.) (2) Example of verbal instructions for 4 to 6 year olds. (a) (Bring the child into position to face the audiometer. With a 50 dB 1000 Hz tone in one phone, hold it to the child's ear.) We are going to see how well you can hear some tones from these earphones. Listen to this one. (b) Every time I play a tone, the red light goes on. Do you see it? (Demonstrate) (c) If you listen carefully and hear the tone, you can turn it off by pressing this button and making the white light on on. (Indicate by depressing response button.) (d) (Hand the response button to the examinee and present tone, encouraging the child to press the response button. When he does, release the stimulus tone. Repeat the sequence at least once or until you feel that the child understands his task. Reinforce the child's performance with a positive comment.) Good. Now we will play this game while you sit in that chair. (Indicate the chair and hand the child the response button.) (e) (Place the headset on child.) First you will hear the tones in this ear (indicate right or left) and then you will hear them in your other ear. (f) Are you ready? (3) Examples of verbal instructions when masking of the better ear is required (when the difference between hearing levels of the two ears is 40 dB or greater at any frequency). (a) Now you will hear the tone in your right/left ear (point). (b) At the same time you will hear a noise, like wind, in your other ear (point). (c) The noise is to keep you from hearing the tone in that ear so don't pay any attention to it. (d) I want you to listen for the tones in your right/left ear (point) and press the button whenever you hear them. (e) Do you understand? (If not, clarify as necessary.) d. Conduction of air condition hearing test (1) Take the examinee into the test room and set him opposite the examiner but facing away so that he cannot see the examiner's movements or the equipment being operated. (2) Close the test room doors. (3) Ask the examinee if he has any problems which might affect his hearing -- colds, earache, etc. Record these under "Condition Affecting Test Results." (4) Repeat the instructions briefly. (5) Make sure the ears are not obstructed with cotton before placing the earphones. (6) Place the earphones on the examinee and make sure the earphone opening is over the ear canal and that it has a good seal against the examinee's ear. The red earphone is placed on the right ear; blue on the left. Hair should be pushed away from ears before the headset is placed. (7) Make sure that the audiometer is ready for the test by checking that it is set in the following manner: Air Conduction Setup Channel I Machine dials Correct Setting Channel I monitor Off unless using Channel I output Right/left ON/OFF toggle switch ON AUTO/manual toggle switch Manual Frequency 1000 Hz. Decibels 20 dB Masking Setup Channel II Machine dials Correct Setting Channel II output Off* Channel II monitor Off unless using ON/OFF toggle switch Off* AUTO/manual Manual Frequency and Input N.B. Noise Decibels 60 dB *When masking is required, channel II output should be right/left and the on/off toggle switch is "ON." NOTE: Dials SISI and Speech-Input have nothing to do with either Air Conduction or Masking testing. (8) The 1000 Hz tone is introduced to the first ear to be tested at a level of 20 dB for about 1 second. This should be well within the range of audibility for most examinees and will serve as listening practice. If the tone is not heard at 20 dB, increase the level in 10 dB steps until he responds to it. (9) When the examinee responds, set the intensity dial 10 dB below the previous stimulus intensity (10 dB) and present the tone for 1 or 2 seconds. (10) The procedure for decreasing the level of the tone in 10 dB steps with at least one presentation per level should be continued until no response is obtained. (11) Then increase the intensity dial 5 dB and present a stimulus. (12) If a response is obtained at this level, the intensity is reduced by 10 dB. If no response is obtained, increase the intensity 5 dB. Always descend 10 dB and count the number of responses at the lowest level while ascending in intensity in 5 dB steps. (13) The threshold recorded is the lowest dial reading at which 50 percent or more of the responses are obtained to ascending presentations--that is, 2 out of 3 or 3 out of 5 trials. Below this leel, less than 50 percent response is obtained and above this level, 100 percent response is approached. (14) Enter the proper two-digit entry on the test form. Test the remaining frequencies in the order indicated on the form. (15) Repeat the procedure presenting each successive frequency in the order listed on the examination form to the test ear and then shift to the other ear as indicated on the test form until the pure tone air conduction test has been completed for all frequencies in both ears. e. Masking procedure--(when the difference in thresholds between the two ears is 40 dB or greater at the same frequency.) At any frequency, when the threshold of one ear is poorer than the other ear by 40 dB or more, you must retest the poorer ear using a masking noise in the better ear. When this is necessary, use a masking level of 60 dB no matter what the difference in thresholds is between the two ears. Record these results in the appropriate spaces on the audiometry form. f. Procedure necessary for threshold accuracy (1) Avoid rhythmic presentation of signals to the examinee. The examinee may respond to the rhythm rather than to the sound. This is especially true of younger persons. (2) Avoid a long, drawn-out search for a threshold which tends to lessen the interest and cooperation of the person being tested and to produce fatigue. If necessary, shift to another frequencyand test, then return to the problem frequency later. Note at the bottom of the form any change in the order of the test on the test form. (3) Avoid giving visual or auditory cues when the tone is presented; for example looking at the person each time a tone is presented, making a click with the interrupter switch, or clicking in the intensity dial. (4) Double check the dial reading. (5) Check whether the interrupter switch was at "off" position. (6) Avoid activity which will distract the examinee. (7) Check the response of the examinee occasionally by leaving the tone off for several seconds and then presenting the tone to see if he is responding consistently. (8) Avoid presentation of the test tone for longer than 3 seconds. This may lead to a false response. (9) Count only the ascending responses in determining the threshold. (10) Avoid being influenced by the threshold obtained for the first cycle tone when obtaining the threshold for the second presentation of this tone. (11) Make sure all forms are complete. Record the time the test is finished and the technician number on the control record. When the test is not done or incomplete, record the reason.
