Nonlinearity in the human ear can cause audible distortion not present in the original signal. Such distortion is generated within the ear by intermodulation of a spectral complex, itself containing possible masked components. When psychoacoustic codecs remove these supposedly masked components, the in-ear generated distortion is also removed, and so our listening experience is modified. In this paper the in-ear distortion is quantified and a method is suggested for predicting the in-ear distortion arising from an audio signal. The potential performance gains because of incorporating this knowledge into an audio codec are assessed.:
