We propose a system for recognizing horn and siren sounds. We calculate the degree of harmonic structure from the amplitude spectrum and search its peaks. The peak frequency corresponds to the fundamental frequency of warning sounds. The experimental results show the method can detect warning sounds in SNR of 0dB.
