Parametrics

Carkit Applications

 In cars, sound is reproduced by the car’s speakers or by the speakers of a carkit. Hands Free is optimized for use in carkits and cancels the acoustical echo in full-duplex calls, so people can have naturally flowing conversations without having to repeat themselves. Hands Free also removes stationary background noise, from the engine, for example, so the words come through loud and clear.
