Different types of evoked otoacoustic emissions (EOAEs) such as stimulus frequency emissions, tone burst and click EOAEs, were investigated in the guinea pig. Their correlates on cochlear microphonic potential were also recorded. Although it was confirmed that click EOAEs are difficult to detect in the guinea pig, partly because their delay (2 to 3 ms, measured on tone burst EOAEs) is much shorter than in man, other types of OAE were found in the interval (1.5-5 kHz) for almost every normal animal. Many of their properties were quite different from man, for instance their small number, low level, and the wide frequency range of some of them (up to 500 Hz), suggesting that they represent a sort of continuum. It is proposed that these particularities may not arise from different generating mechanisms but should be correlated with the well-known differences in hair cells patterns.
在豚鼠身上研究了不同类型的诱发耳声发射（EOAE），如刺激频率发射、短纯音和短声EOAE。还记录了它们与耳蜗微音器电位的相关性。虽然已证实短声EOAE在豚鼠中难以检测到，部分原因是其延迟（在短纯音EOAE上测量为2至3毫秒）比人类短得多，但几乎每只正常动物在1.5 - 5千赫兹的频率区间内都发现了其他类型的耳声发射。它们的许多特性与人类有很大不同，例如数量少、强度低，以及其中一些的频率范围很宽（高达500赫兹），这表明它们代表了一种连续体。有人提出，这些特殊性可能并非源于不同的产生机制，而是应与毛细胞模式中众所周知的差异相关。
