TIME-DOMAIN MODELING OF PERIPHERAL AUDITORY PROCESSING - A MODULAR ARCHITECTURE AND A SOFTWARE PLATFORM

A software package with a modular architecture has been developed to support perceptual modeling of the fine-grain spectre-temporal information observed in the auditory nerve. The package contains both functional and physiological modules to simulate auditory spectral analysis, neural encoding, and temporal integration, including new forms of periodicity-sensitive temporal integration that generate stabilized auditory images. Combinations of the modules enable the user to approximate a wide variety of existing, time-domain, auditory models. Sequences of auditory images can be replayed to produce cartoons of auditory perceptions that illustrate the dynamic response of the auditory system to everyday sounds.
