Abstract

In this paper, selected acoustical parameters were used to evaluate the acoustical qualityof an indoor open space. The parameters included the sound pressure level, reverberationtime, and speech transmission index. The selected parameters were also used to calibrateand verify the accuracy of an indoor acoustic model. Next, room treatment measureswere incorporated into the model, for the purposes of improving the test space’sacoustical quality. The revised acoustic model showed the room treatments were effectiveat improving the space’s acoustical quality and confirmed the effectiveness of using thecalibrated acoustic model process. The playback of the convolved audio signaldemonstrated a reduction in the reverberation time and improvement with speechintelligibility. This paper demonstrates that the acoustical model can be used in themodelling of other spaces such as open-plan offices and industrial facilities. Acousticaltreatments, if required, can be verified in the model.Keywords: room acoustics, impulse, reverberation, speech transmission index, CadnaR.
