Abstract :
In this paper we present a subband scheme to decrease the computational complexity of simulating room responses to acoustic signals, important for instance in microphone array systems. Besides, the new method offers added flexibility to the well known image method by allowing to choose the reflection coefficients of every frequency subband independently of each others. The efficiency of this method is tested experimentally
