Image methods have been successfully used in the analysis of the acoustic properties of enclosures for the purpose of architectural design. In this paper we disuss use of image techniques for simulating the impulse response between two points in a small room. The resulting response is then convolved with any desired input signal and the reverberated output used for signal processing or psychoacoustic studies. The entire process is carried out using a digital computer so that bide ranges of parameters ran be simulated with perfect control over experimental conditions.
