We developed a non-speech sound recognition system with sound source direction estimater. Ten types of single impulsive sounds are recognized at the rate of 80% in a second. A delay-sum beamformer with 16 cbannels microphone array reduces environmental noise by -10 dB and estimates source direction at 10 degree resolution. The system is made on dual pentium PC and the processing is almost realtime. Thousands of non-speech sounds recorded in an anechoic room are gathered into a RWC Database that is open for academic use.
