Abstract

A survey on the architectural acoustic performance of diverse facilities in Aomori prefecture was carried out and mutual relations of various acoustic indicators were investigated. As the results of the survey, the followings were revealed. The value of STI sufficiently corresponds to Reverberation-time, Clarity and Deutlichkeit. The tendency that STI converges a constant value in the range of its small value was not observed.
