Talking Through Ambient Noise

Sonoware, a young Kiel firm founded by four signal processing experts, has launched in-vehicle communication software designed to facilitate conversation in a moving car. Engine and road noise, as well as the radio and other sound sources such as talking GPS can make discussions among vehicle occupants very difficult. To counter this, a series of microphones and speakers captures, modifies and rebroadcasts conversations in real time, suppressing ambient noise and amplifying speech volume. The algorithm suppresses feedback and enables conversation between front and rear seat passengers with minimal delay. The four partners hope to integrate their product into vehicle audio packages made by auto industry suppliers. Since the hardware and software of these systems vary, Sonoware has designed its product to run on a variety of platforms. It also can be adapted to specific customer needs.
