不同时程条件声暴露对豚鼠听力和耳蜗噪声损伤的影响(英)
Effects of different duration of conditioning exposure on hearing loss andcochlear damage following noise trauma in guinea pigs
篇首:Recent studies have shown that the degree of noise-induced hearing loss depended not only on the totalamount of energy received by the listener, but also on thesubject' s previous history of noise exposure. Two phe-nomena known as "toughening" have been observed: ①the progressive resistance to temporary threshold shift(TTS) produced by repetitive exposures to a low levelnoise, and ②the protection against permanent thresholdshift(PTS) produced by being exposed to a nontraumatic"conditioning" noise administered before a higher levelnoise exposure. The present study is to indicate the ef-fects of different period of conditioning exposure on guineapig's hearing loss and cochlear damage from noise trau-ma.
