Research on Improving Room Sound Field of Exhibition Building

Abstract

Generally, there is a high background noise and long reverberation time and poor speech intelligibility in exhibition space due to its big crowd and often commercial promotional activities so that communication is very hard, commercial activities broadcasting system is also difficult to ensure that customers can clearly hear the propaganda content. In this paper, through measured background noise of the new exhibition center in Chengdu, we found the acoustic problem in exhibition space, then we did simulation analysis in some exhibition building and took some acoustical process to get a good sound field.
