Modelling Acoustic Room Interaction for Pistonic and Distributed-Mode Loudspeakers in the Correlation Domain

Document Thumbnail

AES paper 5732 presented a mesh-less, analytic 3-D solution to the problem of an acoustic source located in a nonanechoic room. By applying the inverse Fourier transform, temporal data was extracted to form a complete time and frequency domain description. This paper uses the same model to investigate the correlation properties of the acoustic radiation. Maps are produced, showing how the correlation varies with position in space. Statistical analysis suggests a possible objective classification of the diffuseness of acoustic fields by scalar quantities such as mean and standard deviation of correlation coefficient values. The distribution of correlation values is seen to follow the beta distribution quite closely.
