TYMPANOMETRY Tympanic membrane compliance was tested for all examinees aged 6-19 years by a trained examiner in a soundproof room in the mobile examination center (MEC). A screening questionnaire administered before audiometry testing also determined tympanometry test exclusions and can be used to assess factors that might have affected tympanometry results. If an examinee reported that either ear had a tube (AUPA9) or drainage (AUPA10), tympanometry was not performed, and all tympanometry variables are blank. Analysts should refer to the Audiometry section of the examination data file for information on the screening questionnaire. In addition, questions on hearing status, including ear infection history and the use of hearing aids, can be found in the Household Youth Data File (ages 2 months-16 years). Because this examination was administered in the mobile examination center, the MEC examination sample weight (WTPFEX6) should be used for data analysis. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). The tympanometer (Model TA-7A Automatic Impedance Meter, Teledyne Avionics, Charlottesville, VA) produced a paper tympanogram output and was connected to a personal computer for electronic data collection. Tympanometer function was checked daily. If a unit did not meet specifications, it was sent for service, and a backup unit was used for examinations. Laboratory calibration on each unit was performed approximately twice a year. For details of equipment maintenance procedures, analysts should consult the Audiometry and Tympanometry Manual (U.S. DHHS, 1996b). Training for tympanometry was combined with that for audiometry. At the time of hire, examiners received extensive instruction from the audiometry consultant, and the examiners' performance was monitored on a periodic basis. Hearing evaluation, which included audiometry and tympanometry, was a priority component at three of four annual MEC team retrainings. The variables containing equivalent volume at various pressures (TYPC000L-TYPC120L, TYPC000R-TYPC120R) can be used to create tympanogram plots of compliance as a function of pressure. To do so, the analyst must rearrange the data to have 121 observations per examinee (one for each pressure value at which compliance was determined from -400 to 200 daPa in 5 daPa increments) and create a variable to record the associated pressure values. An example of SAS programming code to perform this rearrangement is included in the note for TYPC000L-TYPC120L and TYPC000R-TYPC120R. This data file includes 242 variables with equivalent volume data for pressure values between -400 and 200 daPa. Many examinees have data for pressure values of -200 daPa or greater but have no data (blanks) for pressure values from -400 to -205 daPa. This is due to variability in a software setting on the tympanometer that toggled an option for continuing readings to -400 daPa or stopping the pressure at -200 daPa if a compliance peak occurred before -175 daPa. There are data for pressures between -400 and -205 daPa for 1156 left ear observations and 1166 right ear observations. Of these observations with data for pressures lower than -200 daPa, only 192 left ear observations and 200 right ear observations had pressure at peak compliance values of -175 daPa or lower. When plotting tympanogram data, analysts may want to include data points for pressure values between -400 and -205 daPa. However, in most cases, this pressure range will not add useful tympanogram information. Early in the survey, electronic data collection was not fully operational, and sporadic equipment problems led to data loss throughout the survey. In these cases, the tympanogram data points (TYPC000L-TYPC120L, TYPC000R-TYPC120R) are not available. However, the values for peak compliance (TYPCMPLL, TYPCMPLR), pressure at peak compliance (TYPPRSPL, TYPPRSPR), canal volume (TYPVOLL, TYPVOLR), and acoustic reflex (TYPRFXL, TYPRFXR) were entered into the data from the hard copy tympanograms if they were available. Data processing and editing were performed to ensure internal consistency of data. Notes have been provided for variables requiring additional explanation.
