Abstract

A model of auditory signal detection, based on a previously investigated electrical model devised by Jeffress, was simulated digitally. The model consisted of a bandpass filter followed by a demodulator comprising a half-wave rectifier and a post-detection integrator. The detection performance of the model for gated sinusoids masked by noise was studied as a function of both the duration of the signal and the time-constant of the post-detection integrator. The performance of the model agreed well with that of the electrical model for comparable conditions.
