Prediction of sound levels in rooms with local- and extended-reaction surfaces

M. Hodgson, A. Wareing

Abstract


A new wave-based model which predicts steady-state sound-pressure levels in rooms bounded by extended-reaction surfaces has been developed and used to study the effect of modeling room surfaces as of extended or of local reaction.
