Voice Enhancement and Noise Reduction Module

Product profile and purpose

The voice enhancement and noise reduction module is adaptive to military communication and mobile communication under various strong background noises, and by detecting enhancement of the band noise voice, it can judge whether there is someone talking at the moment under existence of background noise, and can reduce the background noise, to extract valid voice. It plays an active role in improving the voice communication capacity under strong background noise environment. The voice enhancement and noise reduction module can be applied in any part of the link from voice sender to voice receiver, and can be connected in series to the communication channel.

Main technical parameters

Main characteristics

●  Adaptive to multiple noise environments: It adopts voice digital processing technique, and its general algorithm can adapt to most of the noise environments, and it can make algorithm optimization for special application environment.

●  Anti-strong noise: Similar products have been unable to come into normal operation at 110dB, however, our product can still come into good operation under the environmental noise of 120dB.

●  Broad environmental adaptability: It can come into operation under the temperature as low as -40℃, and as high as 75℃, which is beyond the military standard.

●  Small volume, light weight: under the condition of single-channel voice enhancement and noise reduction, dimension of the module does not exceed 30mm*30mm, and its weight is less than 30 g.

●  Low power consumption: It adopts low power consumption chip, the power consumption of which is less than 500 mW.
