The "Duplizitätstheorie" of Meyer zum Gottesberge (1948) states that signal processing takes place at low sound intensities on the nerve fibers of the outer hair cells, whereas at high sound intensities on the nerve fibers of the inner hair cells. The discovery of oto-acoustic emissions by Kemp (1978) makes a modification of the "Duplizitätstheorie" necessary. The outer hair cells are supposed to be motor-drives final control elements to enhance the sensitivity of inner hair cells. Thus outer hair cells do not serve for the direct transmission of information in the sense of neural coding. Signal processing takes place at all intensities exclusively on the nerve fibers of the inner hair cells.
迈耶·祖姆·戈特斯贝格（1948 年）的“双重理论”指出，信号处理在低声强时发生在外毛细胞的神经纤维上，而在高声强时发生在内毛细胞的神经纤维上。肯普（1978 年）发现耳声发射后，有必要对“双重理论”进行修正。外毛细胞被认为是运动驱动的最终控制元件，以增强内毛细胞的敏感性。因此，外毛细胞在神经编码意义上并不用于信息的直接传递。信号处理在所有强度下都仅在内毛细胞的神经纤维上进行。
