The spatial coherence of noise fields evoked by continuous source distributions

Buerger, M; Abhayapala, Thushara; Hofmann, C; Chen, H; Kellermann, W


In this work, analytic expressions for the spatial coherence of noise fields are derived in the modal domain with the aim of providing a sparse representation. For this purpose, the sound field in a region of interest is expressed in terms of a given pressure distribution on a virtual surrounding cylindrical or spherical surface. According to the Huygens-Fresnel principle, the sound pressure on this surface is represented by a continuous distribution of elementary line or point sources, where...[Show more]
