Microphone Response in a Closed-Loop System

Authors: Pincus, Michael S.

AES Convention 116 · Paper 6158 · May 2004

Abstract

A closed-loop audio system can be defined as one in which the loudspeaker is in the same space as the microphone. As such, some sound from the loudspeaker will mix with the source creating an interference pattern. The interference is dependent on the path length from the loudspeaker back to the microphone, the amplitude of the interfering signal, and the latency of the forward-fed signal. This paper will investigate this interference and its effect on the output response of the microphone.
