Component Description

The NHANES 2017-2018 audiometry examination component (variable name prefix AUX) consists of four parts:

1) Pre-exam audiometric question – a series of questions to identify conditions that would affect how audiometric testing is conducted, or how results are interpreted. Questions include whether the participant has ear tubes, a current cold or ear problem, recent loud noise exposure, and listened to music with earphones in the past 24 hours. NOTE: more extensive data relating to a survey participant’s hearing status and history of noise exposure are contained in the audiometry questionnaire (AUQ) section of the NHANES Sample Person Questionnaire.

2) Otoscopy – a brief otoscopic screening (physical) exam of the ear canals and eardrums to identify abnormalities, which would require alternate audiometric procedures or influence interpretation of test results, and to identify conditions which might require medical referral. The exam screened for excessive or impacted ear cerumen (wax), physical abnormalities, or collapsing external ear canals.

3) Middle ear testing – a measurement of eardrum compliance by placing a probe with a rubber tip into the entrance of the ear canal. It is used to identify middle ear pathologies that might contribute to a hearing loss. There are three middle ear tests: tympanometry, wideband reflectance, and acoustic reflex. The AUX_J data file consists of tympanometric quantitative measurement variables for middle ear volume, pressure, compliance, and gradient. It also includes tympanogram quality ratings and scores variables. The raw data for the participant's tympanometric curves (AUXTYM_J), wideband reflectance curves (AUXWBR_J), and acoustic reflex curves (AUXAR_J) are released separately.

4) Pure tone air conduction audiometry – a measurement of hearing sensitivity by presenting pure tone signals to the ear through earphones and by varying the intensity of the signals until a participant’s hearing threshold at that frequency is determined. Testing is performed at frequencies across the range of human hearing.

Eligible Sample

All participants aged 6–19 years and 70 years and older were eligible. There were no precluding conditions for any part of the audiologic exam. However, participants using hearing aids who were not able to remove them for testing and participants who had sufficient ear pain at the time of the exam that they could not tolerate headphones were excluded.

Protocol and Procedure

All audiometry exam sections were performed by trained examiners on participants in a dedicated sound-isolating room in the Mobile Examination Center (MEC). Hearing threshold testing was conducted on both ears of participants at seven frequencies. Children aged 6–11 years were tested in the following frequency order so that data may be obtained for more important frequencies first in case the child’s attention wanes before all frequencies can be completed: Ear 1: 1000, 2000, 1000 (repeat), 4000, 8000 Hz. Ear 2: 1000, 2000, 1000 (repeat), 4000, 8000, 6000, 3000, 500 Hz. Ear 1: 6000, 3000, 500 Hz. Adolescents aged 12–19 years and adults aged 70 years and older were tested in the frequency order 1000, 500, 1000 (repeat), 2000, 3000, 4000, 6000, 8000 Hz for ear 1 and then for ear 2. The ear tested first was varied to prevent biasing the data. However, if the participant indicated one ear hearing better than the other, the ear with better sensitivity was tested first. Testing was conducted according to a modified Hughson Westlake procedure using the automated testing mode of the audiometer. The approximate audiometer output constraints for standard and insert earphones was 100 decibels (dB) at 500 to 6000 Hz and 90 dB at 8000 Hz. Some earphones might produce slightly higher output than others. A threshold greater than 90 dB can be obtained using a manual testing mode. Observed values, therefore, varied between -10 and 110 dB. If a participant did not respond to the signal tone at any level for one or more frequencies because of deafness or severe hearing loss, a code value of 666 was entered. Manual testing was conducted on children aged 6-8 years. Manual testing was also conducted when the participant could not operate the response switch or responded too slowly for the audiometer to accurately record the response.

In some instances, if a pure tone audiometric signal is sufficiently loud, it can "crossover" and be heard by the opposite ear via bone conduction. When this occurs, it is difficult to determine if the threshold obtained is truly the threshold of the test ear, or an artifact of the non-test ear (which may have better hearing). For the NHANES hearing threshold testing, a crossover retesting protocol was performed whenever the observed threshold at any given frequency was poorer in one ear than the other by 25 dB at 500 and 1000 Hz or 40 dB at any higher frequency. Retesting was accomplished using insert earphones, which are smaller and have less direct contact with the bones of the head. Thus, a much louder stimulus is required before crossover occurs. Due to the complexity of the procedure, masking was not employed in the NHANES audiometry exam.

Quality Assurance & Quality Control

Instrumentation for the audiometry component included an Audiometric Research Tool (ART) system with standard TDH-49P headphones and Etymotic EarTone 3A insert earphones. Interacoustics Titan (middle ear analyzer) was used to conduct middle ear testing. Daily monitoring ambient noise levels was accomplished with a Quest Model BA-202-27 Bioacoustic Simulator. AUX data were entered directly into the computerized NHANES database system. Data from the ART system and Interacoustics Titan were captured electronically and uploaded into the survey information system automatically.

Beginning in the 2017-2018, the ART system was used to conduct the pure-tone air conduction hearing test on survey participants. The ART system is a comprehensive, high configurable audiometer designed for the research application. The ART system consists of a dedicated National Instruments hardware and ART software as an audiometer. The ART software has been programmed to conduct the threshold test automatically and can also be used to conduct the threshold test manually. The ART system also contains an integrated calibration system, called Trident, to measure the sound levels put out by the system. A G.R.A.S. calibration kit with couplers for each type of earphones is used in conjunction with the ART to monitor calibration. The ART calibrations include the Trident software itself check, the background noise measurement, an acoustic calibration check (to measure the output, distortion, and linearity of the audiometer through both standard and insert earphones), and a listening check (tone quality, attenuator accuracy, headphone cords, crossover, etc.). The ART calibration checks were conducted at the beginning of each survey location, daily throughout the entire exam, and at the end of each survey location to ensure that the accuracy has not shifted. In addition to these calibration checks, each ART system received an exhaustive calibration once a year or whenever unresolvable problems were discovered during the calibration checks. The calibration must be accomplished by the manufacturer or a certified laboratory to ensure that the calibrations are traceable to the National Institute of Standards and Technology (NIST).

An Interacoustics Titan was used to conduct middle ear testing. The physical volume was checked on the Titan to ensure that it was within the calibration limits. In addition, the MEC Health Technicians ran a sample test on one ear to ensure that the unit is producing clear, normal graphs for the tympanogram and wideband reflectance. The Titan calibration checks were conducted at the beginning of each survey location, daily throughout the entire exam, and at the end each survey location. The Titan also received an exhaustive NIST-traceable calibration check annually.

A Bioacoustic Simulator was used to continuously measure the background noise levels in the audiometric test room during the exam. Pure tone audiometric testing was not performed if ambient noise levels in the test booth exceeded maximum permissible levels. The microphones and sound measurement function of the bioacoustic simulator were checked by a certified laboratory annually or whenever unsolvable problems were discovered.

As an additional quality measure, all audiograms, whether conducted in automated or manual mode, tested the 1000 Hz frequency twice in each ear as a measure of the reliability of the participant’s responses. Pure tone audiograms were not accepted if there was more than a 10 dB difference between them. For further details regarding any of these procedures, analysts should consult the NHANES 2017-2018 Audiometry Procedures Manual.

The MEC health technicians who performed the audiometry examination component of NHANES were professionally trained by a certified audiologist from the National Institute for Occupational Safety & Health (NIOSH). NIOSH also monitored the performance of each health technician on a regular basis. Field visits to each MEC were conducted by the NIOSH audiologist at least three times per year. Additionally, NCHS project officers visited the MECs approximately twice per year to observe the audiometry examinations and verify that standard testing procedures were being followed. NIOSH consultants provided the MEC health technicians with annual retraining and protocol updates.

The quantitative tympanometry measurements reported in this data file represent the single best of each of the two curves obtained during middle ear testing. Subjective quality ratings for these tympanograms are the variables AUAREQC and AUALEQC. These represent a qualitative assessment of each tympanogram by the consulting audiologist. The consulting audiologist also scored these tympanograms using a common classification system developed by Liden (1969) and modified by Jerger (1970). Two variables AUATYMTR and AUATYMTL provide information about what the tympanometry results mean in terms of the participant’s middle ear status.

Data Processing and Editing

The wording of some questions asked before the audiometry exam has been simplified for children aged 6–11 years. Therefore, there are two separated sets of variables for the pre-exam audiometric questionnaire: one for children aged 6–11 years and another for adolescents aged 12–19 years and adults aged 70 years and older.

All data were captured in the NHANES computerized database system, with audiometric and middle ear analyzer data automatically uploaded. On a continuous basis, a consulting audiologist performed a clinical review of all data for each participant as it was received, checking for quality and consistency. In addition, a computerized data editing program was developed to check for logical inconsistencies in the data and technician errors, and to cross-check other issues affecting data quality (consistency in identifying potential instances where crossover effects might have occurred, assurance of randomization of the initial test ear, etc.). Back-end edits of the data were performed as needed when errors were detected.

Analytic Notes

This examination was administered to a full sample of participants in the MEC. Therefore, the NHANES MEC examination weights should be used for data analysis. For more information on the use of sample weights in current NHANES data analysis and for combining data across multiple NHANES survey years, please refer to the NHANES Analytic Guidelines and the online NHANES Tutorial for further details on the use of sample weights and other analytic issues.

Audiologic data analysis is a complex procedure and requires a thorough knowledge of the specialty content area for valid results to be obtained. If an analyst does not have professional experience in this area, it is recommended that audiologic consultation be obtained to help formulate and review the results of the analysis. Data analysts should be especially aware of the fact that the number "666" in all primary audiometric frequency data fields (AUXU1K1R through AUXU8KL) as well as in all repeat test frequencies (AUXR1K1R through AUXR8KL) is a qualitative code for nonresponse at a particular frequency and does not represent actual measured decibel hearing threshold values. These nonresponse values should be appropriately edited prior to any numerical data analysis.
