Source Directivity Simulation in Numerical Time Domain Methods
Research Student: Jonathan Sheaffer
Modelling directive sources in virtual acoustic environments is key to successful auralisations and accurate room impulse responses. Especially in non-statistical soundfields, such as in small rooms for sound reproduction, source-boundary interactions have a major effect on sound colouration and localisation of phantom images. In this project we are studying various methods for modelling directive sources in numerical time domain methods such as the FDTD and DWG. Particularly, we are looking for efficient ways to model the radiation patterns of real loudspeakers in real rooms.
