Convention Paper

Selection of Loudspeaker Positions for Reverberation Time and Sound Field Measurements

Authors: Prokofieva, Elena

AES Convention 126 · Paper 7694 · May 2009

Abstract

According to the various Building Standards, the source loudspeakers and receiving microphones during the internal noise level measurements can be placed “in any convenient position”, with just some distance restrictions from the nearest reflecting surfaces. In rooms of different shapes and volumes the location of the source and receiver microphone may significantly affect the measured results. If the difference between the reverberation times or noise levels measured for two positions in the same room exceeds 10%, they cannot be averaged. The simulation program is created to recommend the most suitable locations for microphone and loudspeakers in tested room for reverberation time measurements. The results of series of tests are analyzed to confirm the results of the simulation.
