Topographic organization is essential for pitch perception.

P itch is the perceptual attribute we associate most with melodies in music, patterns of bird songs, and the distinctions between speakers’ voices. It plays a key role in the organization, segregation, and identification of sound sources in cluttered auditory scenes because it is derived from acoustic cues that closely reflect the material and geometric properties of resonating objects. Pitch h...

Correct tonotopic representation is necessary for complex pitch perception.

The ability to extract a pitch from complex harmonic sounds, such as human speech, animal vocalizations, and musical instruments, is a fundamental attribute of hearing. Some theories of pitch rely on the frequency-to-place mapping, or tonotopy, in the inner ear (cochlea), but most current models are based solely on the relative timing of spikes in the auditory nerve. So far, it has proved to be...

Pitch 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 ...

6 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...
