The ear introduces spectral components which are not present in the stimulating sound. These components are commonly attributed to nonlinearities in the inner ear. In this paper it is shown that the sum product of f1 + fh and cubic sum product 2f1 + fh, perceptively measured, do behave as predicte d by the conventional distortion theory of a power series nonlinearity and that they are most likely masked by the d.c. component generated by the same nonlinearity. We present a model in an attempt to explain the data.
耳朵会引入刺激声音中不存在的频谱成分。这些成分通常归因于内耳的非线性。本文表明，经感知测量，f1 + fh的和积与立方和积2f1 + fh的表现正如幂级数非线性的传统失真理论所预测的那样，而且它们很可能被同一非线性产生的直流分量所掩盖。我们提出一个模型以试图解释这些数据。
