Sound field reproduction around a scatterer in reverberation
Terence Betlehem, Mark A. Poletti · 2009
We devise a method for sound field reproduction (SFR) around a solid object in a reverberant room. Until now, work have focussed on reproducing sound in an empty listening space and, for the most part, in non-reverberant environments. However, in a reverberant, room as soon as a listener steps into the space he alters his acoustic environment, generating a sound component which is body-scattered and successively reverberated throughout the room. Building on the model of the sound field around a solid sphere in free space, we extend to reproduction around a human head in a reverberant room. In doing so, we show the relationship between the pressure matching and mode matching approaches of SFR.
