一种吸声系数现场测量装置
Sound Absorption Coefficient Field Measuring Device in-situ
摘要
Abstract
To solve the defects of the existing methods for measuring the sound absorption coefficient,and to realize testing the sound absorption coefficient in-situ,an in-situ sound absorption coefficient measurement setup is developed.The in-situ measurement device was developed based on the sound reflection method,combined with the time selection window and wave elimination technology.The sound absorption coefficient wass measured by the developed measuring device in-situ,and the results were compared with those obtained by the reverberation chamber method and the standing wave tube method.关键词
