Interaural attenuation for Sennheiser HDA 200 circumaural earphones.

Brännström, Jonas LU and Lantz, Johannes (2010) In International Journal of Audiology 49(6). p.467-471
Abstract
Interaural attenuation (IA) was evaluated for pure tones (frequency range 125 to 16000 Hz) using Sennheiser HDA 200 circumaural earphones and Telephonics TDH-39P earphones in nine unilaterally deaf subjects. Audiometry was conducted in 1-dB steps using the manual ascending technique in accordance with ISO 8253-1. For all subjects and for all tested frequencies, the lowest IA value for HDA 200 was 42 dB. The present IA values for TDH-39P earphones closely resemble previously reported data. The findings show that the HDA 200 earphones provide more IA than the TDH-39P, especially at lower frequencies (<or=500 Hz). It is concluded that contralateral masking should be applied during pure-tone audiometry with the HDA 200 earphones when the... (More)

It is concluded that contralateral masking should be applied during pure-tone audiometry with the HDA 200 earphones when the level at the test ear is more than 40 dB above the threshold of the non-test ear.
