Periodicity Pitch and Related Auditory Process Models

Abstract

Schouten's (34-38) residue and other phenomena call for extension of place theory to account for the role of periodicity in determining subjective pitch. This paper examines several mechanisms that might be used by the auditory system to recode the information carried by the time pattern of the output of the cochlear frequency analyzer. A distinction is made between mechanisms that involve ordered arrays of components and mechanisms that involve unordered arrays. The relation of periodicity mechanisms to „property filters” is examined, and periodicity pitch is discussed in relation to „sharpening” and binaural interaction.
