Simulation of sound in rooms

Abstract

Computer modelling of room acoustics was proposed during the 1960s by Schroeder et al. (1962) and used in practice by Krokstad et al. (1968) and Schroeder (1973). Although room-acoustic scale model experiments are still a powerful tool today, computer simulations are increasingly taking over the part of scale models in consulting. Commercial software became more user-friendly, more accurate and, last but not least, cheaper than scale models. As soon as the architectural plan is transferred into a computer file and the wall data, source and receiver locations are defined, the sound propagation in the room can be simulated quite fast, and modifications can be tested without large effort.
