Abstract:

Eight males were exposed for three minutes to a 4000 cps fatigue tone at 40 dB SL. Each S was tested under four task-conditions: mental arithmetic (MA), written ling division (LD), threshold determination of a 500 cps tone (TD), and reverie (REV). Temporary threshold shifts (TTS) were computed by comparing pre- and post-fatigue thresholds, MA produced significantly more TTS than any other condition, and LD resulted in greater shifts than REV. Amount of auditory fatigue can vary with the type of mental activity performed by the S.
