Abstract
20 guinea pigs were exposed to a broad band noise (120-140 dB SPL) for short durations. The conditions of stimulation were strictly identical for all animals. Cochlear microphonic responses (CM) were recorded with conventional differential electrodes after each exposure, from the first turn of the cochlea. Variations were observed in the degree of CM depression and also in the alteration of the CM transfer function. The origin of this variability is discussed.
摘要
20只豚鼠短时间暴露于宽带噪声（120 - 140 dB SPL）。所有动物的刺激条件严格相同。每次暴露后，用传统差分电极从耳蜗第一圈记录耳蜗微音响应（CM）。观察到CM抑制程度以及CM传递函数变化存在差异。讨论了这种变异性的起源。
