Use of an auditory model to explain the mechanism of pitch discrimination

摘要

The number and nature of the mechanisms of pitch discrimination in the human ear is not clearly understood. To deepen our understanding of the mechanism involved in perceiving pitch, we have used the auditory model of Meddis and Hewitt (1991). We optimised the parameters and measured the jnd of the model for sinusoidal stimulus. Comparison of our experimental findings on the mechnism of pitch discrimination, reported earlier, and the performance of the model indicates the single mechanism operating in discriminating pitch.
