Acoustic Environment of Large Terminal Airside Concourse in China

Abstract

This study uses the model of the airside concourse of a certain terminal building in China, which is under construction, and compares the indoor reverberation time with six different indoor heights and different situation of unoccupied and occupied indoor field. The results of the study show that due to the narrow design of the airside concourse and the large number of glass curtain walls, the insufficient indoor sound absorption will result in - in the case of unoccupied field - the reverberation time of the 500Hz at 20m height terminal lasts as long as 7.2 seconds. With each 1m lower in height, the reverberation time increases by 0.16 seconds. The conclusion of this study is that, in the case that the indoor sound absorption cannot be increased and the number of indoor people is fixed, reducing the height of the terminal building helps to reduce the indoor reverberation time.
