Subjective spatiotemporal matrix as a new measure of sound field distribution in a room

Abstract

A new approach for representing the acoustic quality of classroom is presented in this paper. The subjective spatiotemporal measure was developed from a 3D scanning plane by using a dedicated scanning gear to measure the subjective volumetric sound field of a listener inside the room. Calculated coherence matrix is derived from spectral comparison on the appropriate scanning planes. It then could be used for indicating the subjective perception of a listener which is may differ to another listener at adifferent position inside the rooms.
