Acoustics of a Japanese Buddhist temple is investigated. We have measured listening levels, subsequent reverberation times, inter aural cross-correlation functions with various sound source positions following the traditional rites of Buddhism and found several characteristics, especially the long subsequent reverberation time BEHIND speakers. Much would be expected also in measurements with symmetry-breaking sound source positions, in Christian churches, concert halls and opera houses.

Key words: Buddhism, temple, wood, stress, violin, sound post, ACF, IACC, broken symmetry
