Silicon modeling of pitch perception.
We have designed and tested an integrated circuit that models human pitch perception. The chip receives as input a time-varying voltage corresponding to sound pressure at the ear and produces as output a map of perceived pitch. The chip is a physiological model; subcircuits on the chip correspond to known and proposed structures in the auditory system. Chip output approximates human performance...
متن کاملPitch perception.
Pitch is one of the primary auditory sensations and plays a defining role in music, speech, and auditory scene analysis. Although the main physical correlate of pitch is acoustic periodicity, or repetition rate, there are many interactions that complicate the relationship between the physical stimulus and the perception of pitch. In particular, the effects of other acoustic parameters on pitch ...
متن کاملCoincidence Detection in Pitch Perception
Pitch plays a critical role in the perception of speech prosody, melody of music, and in organizing the acoustic environment into different sources. Like timbre, pitch refers to many distinct percepts with a host of confusing terms. They include “spectral pitch” evoked by sinusoidal signals, “residue pitch” associated with unresolved (high) harmonics, very slow click trains, and envelope of amp...
متن کامل6 Pitch perception models
This chapter discusses models of pitch, old and recent. The aim is to chart their common points – many are variations on a theme – and differences, and build a catalog of ideas for use in understanding pitch perception. The busy reader might read just the next section, a crash course in pitch theory that explains why some obvious ideas don’t work and what are currently the best answers. The bra...
