AES Convention 144 · Paper 9960 · May 2018

Abstract

Comparison of static multi-microphone measurements are made to moving microphone measurements for the purposes of determining room response and for application of appropriate equalization. Several benefits of moving microphone measurements are shown in this paper including consistency of measurements and the ability to measure interaction of correlated signal from multiple sources without the obfuscation of combing artifacts. It is also shown that moving microphone measurement is consistent with multiple microphone spatial average of sufficient resolution. This paper focuses on the moving microphone technique in the cinema application and experiments conducted were done in a medium sized cinema auditorium.
