A psychophysical study of spectral hyperacuity.
Frequency modulation (FM) of primary tones is transposed to FM of distortion products which are lower in frequency. Since the auditory system is more sharply tuned at low frequencies there is an increase in sensitivity to FM via this transposition. The increased sensitivity is reduced when distortion products are masked.
