Comparison of TCAC and Manual Audiometry.

Abstract

Hearing threshold level was measured with Tone-Count Audiometric Computer (TCAC) audiometry and with manual audiometry on 100 subjects. TCAC yielded higher threshold at 3000, 4000, and 6000 Hz, with the average differing by about 2 dB except at 6000 Hz for the left ear, which average differed by about 5 dB. At 500, 1000, and 2000 Hz an interaction between technic and test order emerged; TCAC and manual was tested first. This same when TCAC was given first, but TCAC poorer when manual was tested first. This study established that TCAC audiometry is comparable with manual audiometry for hearing conservation and physical standards purposes. (Author)
