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

The reverberance of sound fields was evaluated by psychological tests in a multi-purpose hall with 400 seats. Both the subsequent reverberation time (Tsub) 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 Tsuband SPL have an independent influence on the scale value of reverberance. The reverberance increases when both Tsuband SPL are increased.
