REVERBERANCE OF AN EXISTING HALL IN RELATION TO BOTH SUBSEQUENT REVERBERATION TIME AND SPL

Abstract The reverberance of sound fields was evaluated by psychological tests in a multi-purpose hall with 400 seats. Both the subsequent reverberation time ( T sub ) and sound pressure level ( SPL ) were changed, and the scale values of reverberance for both the music and speech signals were obtained by using the paired comparison method. This study found that T sub and SPL have an independent influence on the scale value of reverberance. The reverberance increases when both T sub and SPL are increased.
