Abstract
In a partial replication of a previous experiment by Wojnarowska, 12 normal-hearing adults between the ages of 18 and 26 were given oral 50- or 10-mg doses of atarax or either of two placebos prior to an 8-min exposure to a 1500-Hz tone at 105 dB SPL. Three control and four experimental sessions were conducted. Comparison of pre- and post-exposure thresholds for these indicated that neither the drugs nor the placebos had a significant effect on either the amount or duration of auditory fatigue.
