Lyon (J Acoust Soc Am 130:3893-3904, 2011) has described how a cascade of simple asymmetric resonators (CAR) can be used to simulate the filtering of the basilar membrane and how the gain of the resonators can be manipulated by a feedback network to simulate the fast-acting compression (FAC) characteristic of cochlear processing. When the compression is applied to complex tones, each pair of primary components produces both quadratic and cubic distortion tones (DTs), and the cascade architecture of the CAR-FAC system propagates them down to their appropriate place along the basilar membrane, where they combine additively with each other and any primary components at that frequency. This suggests that CAR-FAC systems might be used to study the role of compressive distortion in the perception of complex sounds and that behavioural measurements of cochlear distortion data might be useful when tuning the parameters of CAR-FAC systems.
里昂（J Acoust Soc Am 130:3893-3904, 2011）描述了如何使用一连串简单的不对称谐振器（CAR）来模拟基底膜的滤波，以及如何通过反馈网络操纵谐振器的增益来模拟耳蜗处理的快速作用压缩（FAC）特性。当压缩应用于复音时，每一对主分量都会产生二次和三次失真音（DT），而 CAR-FAC 系统的级联结构将它们沿基底膜传播到适当的位置，在那里它们彼此相加，并与该频率的任何主分量相加。这表明 CAR-FAC 系统可用于研究压缩失真在复杂声音感知中的作用，并且当调整 CAR-FAC 系统的参数时，耳蜗失真数据的行为测量可能是有用的。
