Insert earphones for audiometry: applications, …
https://pubmed.ncbi.nlm.nih.gov/2692634/
The measurement of hearing sensitivity during audiometry requires precise presentation of auditory stimuli. In most cases, these stimuli are introduced to the listener via standard earphones. Technical problems associated with these earphones have troubled clinicians for years. An alternative earphone system for audiometry was introduced that uses shoulder-worn …

Background: Your letter stated that OSHA’s August 31, 1993 letter to Dr. Fredrik Lindgren provided that, with some conditions, insert earphones can be used to conduct audiometric testing under OSHA’s noise standard. Among other things, the conditions from that 1993 letter provided that the person responsible for conducting the audiological testing must …

During pure-tone audiometry, sounds delivered to the test ear may cross over to the non-test ear through bone conduction, a phenomenon known as crossover. With supra-aural headphones, pure tone signals delivered at a high level, 40 dB or more, can cause the following problem: The headphones’ vibration causes vibration in the skull bones, carrying the signal directly to the non …

https://pubmed.ncbi.nlm.nih.gov/2708692/
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 …
