“…Recent analyses of the NHANES 1999 -2004 dataset showed that diabetes and heavy smoking were associated with increased hearing loss (Agrawal et al 2008;Bainbridge et al 2008). This effect has been seen in other studies (Arlinger 1991;Lutman & Davis 1994) and has been attributed to an error in the reference value for audiometric zero when calibrating TDH-39 headphones on an NBS-9A (6 cm 3 ) acoustic coupler (Robinson et al 1981;Lutman & Qasem 1998;Lawton 2005). Unquestionably, our population smokes far less today than in 1962.…”

For men and women of a specific age, high-frequency hearing thresholds were lower (better) in 1999-2004 than in 1959-1962. The prevalences of hearing impairment were also lower in the recent survey. Differences seen at 500 Hz may be attributable at least in part to changes in standards for ambient noise in audiometry. The National Health and Nutrition Examination Survey 1999-2004 distributions are offered as a possible replacement for Annex B in ISO-1999 and ANSI S3.44.

“…It is seen that apart from at 6000 Hz there is a good agreement between the DD 45 and TDH 39. It is well known and often discussed that the calibration value (RETSPL) for TDH 39 may be incorrect (Robinson et al, 1981;Fearn & Hanson, 1983;Lawton, 2005). Experience has shown that audiometry on normal-hearing persons often shows a probably fake hearing loss of about 5 dB at 6000 Hz if a TDH 39 earphone has been used for the audiometry.…”

This paper describes the determination and results of pure-tone equivalent threshold sound pressure levels for the Interacoustics DD 45 audiometric earphone equipped with standard Model 51 cushions. The size and shape of the DD 45 transducer resembles the classic Telephonics TDH 39 earphone. Pure-tone hearing threshold measurements were performed for both ears of 29 test subjects. All audiometric frequencies from 125 to 8000 Hz were used. The data are intended for inclusion in future standardized reference equivalent threshold sound pressure levels. The results show that the DD 45 may be a good substitute for the THD 39 without the traditional 5-dB problem at 6000 Hz.

“…It is also possible that those with higher executive function were faster to learn the hearing threshold measurement procedure during the test than those with poorer executive function. There are indications suggesting that pure-tone hearing thresholds improve with exposure to the test (Robinson, Shipton, and Hinchcliffe 1981). Furthermore, pure tone hearing thresholds are influenced by several within-subject factors such as physiological noise, adaptation, habituation, temporal integration, ability to participate, willingness to participate, instructions and learning effects (Arlinger 1993).…”

Objective: Pure tone audiometry may seem to be a relatively easy task for the participant but it may involve cognitive as well as sensory abilities. The aim of this study is to examine the relationship between hearing thresholds in the frequency range 0.125-8 kHz and the core executive function cognitive flexibility in healthy individuals with normal hearing. Design: Experimental study measuring correlations between different pure-tone hearing threshold measures and cognitive flexibility. Pure tone air conduction audiometry (frequencies 0.125-8.0 kHz) and two tests of cognitive flexibility (information updating and shifting ability) were conducted. Study sample: Seventy-two subjects (aged between 21 and 36) with normal hearing (<20 dB HL) for the tested frequencies.Results: Four measures of average pure tone hearing thresholds were negatively correlated with cognitive flexibility. Conclusions: Pure-tone air conduction hearing thresholds seem to be related to cognitive flexibility in healthy individuals with normal hearing. ARTICLE HISTORY
