A Perceptual Criterion for Loudspeaker Evaluation

Authors: Kates, James M.

Abstract

A new criterion for evaluating loudspeaker performance is presented. It is based on a monaural model of the human auditory system that accurately predicts the perception of coloration in filtered Gaussian noise. The evaluation procedure produces a single perceived frequency-response curve, termed the central spectrum, that represents the activity of the auditory nerve for a steady-state input. The central spectrum calculation includes both the direct sound from the loudspeaker and the effects of room reflections. The results of using this technique indicates that the early reflections from the floor and from the walls behind and adjacent to the loudspeaker may have an important effect in the perceived frequency response.
