Abstract
Using 110 male albino guinea pigs, and applying electrophysiological m ethods, we investigated the effects of 4 kHz tone at moderate sound pr essure level on the inner ear at different exposure times (6, 12, 24 a nd 48 h). Longer than 12 h exposure to 4 kHz tone had a considerable e ffect on the hearing, inducing a decrease in the maximum output voltag e of cochlear microphonics and an increase in the K+ concentration in the endolymph.
