The Effect of a Hearing Loss on Signal Detection and Frequency Discrimination Performance.

Abstract

Currently applicants for sonar operator must be classified H1 - hearing level not greater than 30 dB between 500 and 6000 Hz in both ears. It is difficult to find a sufficient number of applicants that meet this requirement, and if possible, the CF would like to lower it to H2 (hearing level not greater than 30 dB between 500 and 3000 Hz). For this reason a study was conducted to compare the performance of individuals with moderate hearing losses and those with normal hearing on auditory tasks similar to those carried out by a sonar operator. The results indicated that individuals with high frequency losses (above 3000 Hz) and with moderate conductive impairments, could successfully do such tasks. Personnel classified H2 should be able to carry out the required tasks. (Author)
