摘要
主要介绍AWA6122+型双通道电声测试仪配合有源耦合腔和实验室标准传声器用于测试电容传声器频响的测量。同样也可按IEC61672-3:2006将它作为连续频率的声校准器,测量声级计的声频响。实验表明,用该方法可快速实现测试电容传声器频响测量和驻极体传声器(咪头)的频响测量以及声级计声频响的测量。
The measurement of Model AWA6122^+ dual-channel electroacoustic test system cooperate with active acoustic coupler and laboratory standard microphone on condenser microphone frequency response is introduced. The dual-channel eleetroacoustie test system can be applied to measure sound-signal frequency response of sound meter according to IEC 61672-3:2006 Eletroacoustics-soungd Level Neters-Part 3:Periodic Tests. The experimental results show that this method can measure the condenser microphone frequency response, back eleetret microphone frequency response and sound-signal frequency response of sound meter quickly and effectively.
