School Gymnasium Acoustics - Part 2

Stage 1: Initial Measurement

On first measurement the reverberation time was a whopping 3.8 seconds. (This was done using an RT60 reading which is the time required for reflections of a direct sound to decay by 60dB). During school assembles this was akin to making yourself understood in an aircraft hangar – very frustrating!

RT60 test result prior to acoustic treatment showing a reverberation time of 3.8 seconds.

1.5 seconds is considered an acceptable reverberation time for multi-purpose Gymnasiums, Halls & Events Centres, however, this can only be attained with significant acoustic treatment...
