Abstract
Pregnant guinea pigs were exposed to loom room noise at 115 dBA SPL for 7.5 h per day for various periods during the last trimester of pregnancy. When the hearing of their offspring was tested by brain stem evoked response techniques at 6‐dB intervals, 5th peak latencies of exposed pups were found to be significantly longer than those of otherwise similar control pups. The latency differences corresponded to some 5 dB at medium levels and 10–12 dB near threshold. The results indicate that it is possible for noise‐induced hearing loss to occur in utero in mammals whose auditory maturation process is complete, or nearly so, before birth.
