Spherical harmonics based generalized image source method for simulating room acoustics

Samarasinghe, Prasanga; Abhayapala, Thushara; Chen, Hanchi; Dickins, Glenn


Allen and Berkley's image source method (ISM) is proven to be a very useful and popular technique for simulating the acoustic room transfer function (RTF) in reverberant rooms. It is based on the assumption that the source and receiver of interest are both omnidirectional. With the inherent directional nature of practical loudspeakers and the increasing use of directional microphones, the above assumption is often invalid. The main objective of this paper is to generalize the frequency domain...[Show more]
