各位高手做过蓝牙车载免提测试能否赐教一下?
蓝牙车载免提要如何测试?除了蓝牙无线标准外，声学方面要如何测试呢?谢谢

通话声音够大、不失真、没回声、对环境噪声抑制能力
1. need to test the Frequency response and THD for microphone
2.need to test phase, distortion and deviation of frequency (4~8)dB@1kHz when microphon e1&2 work simultaneously.
3. need to test the echo under differents volume of speaker
4.need to test the S/N
5.need to test Frequency response and THD for speaker
and so on！
