Abstract

The experiment for sound absorption of microforated absorbers is based on maa's heory. The microforated absorbers are used in the gynmasium and its indoor acoustic design with Alsimin panel can satisfy the requirements of large-scale rallies and recreational activities and the requirement of Making TV broadcast relay. Fulfilling acoustical perpormance of the gymnasium has thus beed achieved.
