As a method to extend the efficiency of scale model experimant of room acoustic, the hybrid simulation technique has been developed, in which impulse responses are measured in a 1/10 scale model auditorium and they are convolved with arbitrary anechoic source signals like music and speech by the digital convolution technique. Through these processes, the "hall tones" can be heard in advance of construction of the real auditorium. A spark discharge sound source with high repeatability and broad band spectra has been developed for the impulse response measurement, and a simple model dummy head was used for binaural recording. As the result of various contrvances for computer programming, considerably fast convolution calculation has been realized.
