The prediction of synthesised wavefields within realistic room acoustics scenarios

This paper presents a technique to predict the output from an in-house developed 128 channel wavefield synthesis system deployed within realistic room acoustic scenarios. Based on Finite Difference Time Domain the acoustic prediction detailed here utilises ray based voxellisation and a least pth norm filter design approach to import hall data in popular formats that specify complex room geometries and the frequency dependant absorption profiles of surface materials. Using this approach the objective and subjective fidelity of wavefield synthesis within realistic deployment scenarios can be better understood.
