Comments on ‘‘Earphones in audiometry’’ [Zwislocki e t a l., J. Acoust. Soc. Am. 8 3, 1688–1689 (1988)]

Abstract

The Zwislocki et al. ["Earphones in Audiometry," J. Acoust. Soc. Am. 83, 1688-1689 (1988)] Letter to the Editor states that insert earphones have some unresolved technical problems, such as limited frequency response, limited dynamic range and power handling capability, intersubject variability, and hygiene safety. In evaluating circumaural earphones, Zwislocki et al. say that the lack of a standard coupler disqualifies them for audiometry. Since this letter carries the weight of a CHABA committee recommendation, these issues are commented on herein. Section I was written primarily by Mead Killion and Sec. II primarily by Edgar Villchur. For brevity throughout, the authors of the Zwislocki et al. letter will be referred to as "the authors."

Utilizing Artificial Neural Networks for Establishing Hearing-Loss Predicting Models Based on a Longitudinal Dataset and Their Implications for Managing the Hearing Conservation Program

“…In the present study, pure-tone audiometry was adopted to assess the hearing thresholds of the workers. However, pure-tone audiometry has limitations, including sensitivity to factors such as background noise, cross-hearing with loud sounds, ear canal issues, discomfort from wearing earphones, and challenges in hearing measurement [ 38 ].

Effectiveness of a New Tablet-Based Hearing Screening System Among a Cohort of Individuals With a High Incidence of Hearing Loss

“…Despite this rapid early rise in development, there has been relatively little progress since. In current practice it is recommended [12] and extremely common to use a calibrated test system that uses Telephonics TDH-39 headphones, a design that was conceived for use by the Air Force in World War 2 [13]. There is very little written evidence of the first use of these headphones in audiometry, however they are shown to be commonly used (84% in a study involving 100 audiometers, randomly selected) by 1969 [14].…”
