Description

The purpose of this report is to clarify the effects of sound insulation achieved by installing partitions on a counter. From the results of numerical experiments, the following aspects were clarified. When two parallel partitions are installed on both sides of a speaker and a listener, the sound pressure level at the waiting area is raised. When some booths are compartmentalized on a counter using parallel partitions, the sound insulation to other booths cannot be achieved in the case of partitions with a low absorption coefficient but can be achieved in the case of partitions with a high absorption coefficient.
