The dominance region and ripple noise pitch: a test of the peripheral weighting model.

An estimate of the spatial curve of pitch dominance for the repetition pitch of ripple noise was measured using the pitch strength discrimination procedure. A variety of stimulus conditions were examined. The peripheral weighting model [Yost and Hill, J. Acoust. Soc. Am. 66, 400-410 (1979)] of repetition pitch assumes a relationship between the curve of pitch dominance and the shape of the psychophysical suppression of unmasking function. Ripple noise was also used to estimate the psychophysical suppression or unmasking function. The results indicate that with the estimates of the psychophysical suppression or unmasking function the peripheral weighting model can account for the general shape of the curve of pitch dominance.
