“…Mahomed et al (2013) provides a detailed systematic review and meta-analysis of the literature comparing automated pure-tone air-conduction threshold audiometry with the gold standard of manual threshold audiometry. The researchers conclude that automated audiometry provides an accurate measure of hearing threshold using air-conducted pure-tones as stimuli.…”

Objective To assess the test-retest variability of hearing thresholds obtained with an innovative, mobile wireless automated hearing-test system (WAHTS) with enhanced sound attenuation to test industrial workers at a worksite as compared to standardized automated hearing thresholds obtained in a mobile trailer sound booth. Design A within-subject repeated-measures design was used to compare air-conducted threshold tests (500 to 8000 Hz) measured with the WAHTS in six workplace locations, and a third test using computer-controlled audiometry obtained in a mobile trailer sound booth. Ambient noise levels were measured in all test environments. Study sample Twenty workers served as listeners and 20 workers served as operators. Results On average, the WAHTS resulted in equivalent thresholds as the mobile trailer audiometry at 1000, 2000, 3000 and 8000 Hz and thresholds were within ±5 dB at 500, 4000, and 6000 Hz. Conclusion Comparable performance may be obtained with the WAHTS in occupational audiometry and valid thresholds may be obtained in diverse test locations without the use of sound-attenuating enclosures.

“…A series of validation studies demonstrated that the method produces thresholds with average values that are equivalent to those obtained by experienced audiologists (Margolis et al 2010; Margolis & Moore 2011; Margolis et al 2011). An independent assessment of AMTAS (Eikelboom et al 2013) replicated the finding of equivalence between AMTAS and manual audiometry and a meta-analysis showed good agreement between mean values obtained with automated and manual test procedures (Mahomed et al 2013). AMTAS employs masking based on rules that are consistent with those used in manual audiometry.…”

Objective Five databases were mined to examine distributions of air-bone gaps obtained by automated and manual audiometry. Differences in distribution characteristics were examined for evidence of influences unrelated to the audibility of test signals. Design The databases provided air- and bone-conduction thresholds that permitted examination of air-bone gap distributions that were free of ceiling and floor effects. Cases with conductive hearing loss were eliminated based on air-bone gaps, tympanometry, and otoscopy, when available. The analysis is based on 2,378,921 threshold determinations from 721,831 subjects from five databases. Results Automated audiometry produced air-bone gaps that were normally distributed suggesting that air- and bone-conduction thresholds are normally distributed. Manual audiometry produced air-bone gaps that were not normally distributed and show evidence of biasing effects of assumptions of expected results. In one database, the form of the distributions showed evidence of inclusion of conductive hearing losses. Conclusions Thresholds obtained by manual audiometry show tester bias effects from assumptions of the patient’s hearing loss characteristics. Tester bias artificially reduces the variance of bone-conduction thresholds and the resulting air-bone gaps. Because the automated method is free of bias from assumptions of expected results, these distributions are hypothesized to reflect the true variability of air- and bone-conduction thresholds and the resulting air-bone gaps.

“…The threshold of the lowest level was defined when the participants responded to 50% of the pure tone. The reliability and validity of the automated hearing test was good, as compared to the manual test 1112). When the subjects heard the tone, they were instructed to push a button.…”

BackgroundThe prevalence of hearing impairment is increasing and an association between hearing impairment and mental health has been reported. Our study aimed to determine the association between hearing impairment and mental health in Korea.MethodsThis was a cross-sectional study of data from the Korean National Health and Nutrition Examination Survey 2010–2013, with a sample size of 18,563 individuals (6,395 with hearing impairment and 12,168 without hearing impairment), aged ≥20 years.ResultsThe female group with hearing impairment tended to have a higher rate of stress (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.11 to 1.56). The association between hearing impairment and depressive symptoms was higher in elderly males (OR, 1.60; 95% CI, 1.10 to 2.32), while the association of hearing impairment with suicide ideation was higher in elderly females (OR, 1.32; 95% CI, 1.00 to 1.75).ConclusionElderly individuals with hearing impairment are easily susceptible to poor mental health status. Early targeted intervention to address mental health problems is recommended for people with hearing impairment.

Validity of Automated Threshold Audiometry

Abstract: Automated audiometry provides an accurate measure of hearing threshold, but validation data are still limited for (1) automated bone conduction audiometry; (2) automated audiometry in children and difficult-to-test populations and; (3) different types and degrees of hearing loss.
