Recovery of psychophysical tuning curves following noise exposure. 1987

G D Chermak, and J E Dengerink

Psychophysical tuning curves (PTCs) at 2 kHz and auditory thresholds (2 kHz and 4 kHz) were obtained from 18 normal-hearing listeners before and after exposure to a 5-min 110 dB SPL white noise. PTCs were quantified on five dimensions (Q10 tip, Q10 probe, d1oct, tip level and tip frequency). PTCs revealed continued cochlear effects beyond the time when TTS at 2 kHz demonstrated complete recovery.
