录音传声器隔声罩的设计

摘要

Through insulating acoustic noise and increasing the sound path difference, we designed an acoustic insulation which covered with circular lid. Experimental results show that, this acoustic insulation could improve the directivity of a microphone and restrain the environmental noise effectively.%采用隔声降噪和增加声程差的方法设计了一款圆形加盖隔声罩。实验结果表明，此款隔声罩可以改善传声器的指向性，有效抑制传声器周围的噪声。
