Abstract

Most models of pitch perception assume three basic stages of processing: cochlear filtering, haircell/neural transduction, and pitch extraction. In temporal models of pitch processing the pitch extraction stage is often based on autocorrelationlike processes. This talk will review our work using regular interval stimuli to study temporal models of pitch perception. Work with regular interval stimuli suggests that temporal models of pitch processing can account for the pitch and pitch strength of complex sounds with both resolved and unresolved harmonics. The pitch and pitch strength of regular interval stimuli appears to be based on the temporal properties of the waveform fine structure. Human and animal psychophysical results, physiological recordings from the cochlear nucleus, and model results will be presented. [Work supported by NIDCD and AFOSR.]
