Abstract

Contemporary objective room-acoustic indicators are based on the capture and subsequent analysis of room impulse response but subjective criteria are also influenced by the spatial distribution of sound energy. The spatial distribution of sound energy is usually not considered due to lack of an efficient, accurate and easy to perform measurement procedure. This study introduces three dimensional sound intensity measurement for obtaining spatial information of the sound field in an enclosure. The measurement technique is described and its merits and potential are identified. Specular and diffuse sound field quantification is also introduced
