Abstract:Using the self-adaptive noise reduction technology, the capture couldstudy the room’s noise structure model,and then using theLMS algorithm to limit the filter factors。Product’s Features: The speech pick-up use the double precision floating DSP, including the noise reduction block, equalizer blocks and feedback canceler block, and it can improve the speech signal to noiserate. Usually apply at the speech acquisition
and monitoring.*Adjustable noise attenuation depth from 0-20dB.*Supported external phantom power supplymicrophone such as the boundary microphone, hyper-cardioid microphone and so on. The capture’ssource would switch from internal electret microphone to the external plugging microphone
immediately if inserting the device.Application environment: The Banks, The Courtroom, The Jail, The government’s public service hall, The hearing site and so on, All those need to be monitored.
