Abstract
In this paper we describe a sound classification method, which seems to be applicable to a broad domain of stationary, non-musical sounds, such as machine noises and other man made non periodic sounds. The method is based on matching higher order spectra (HOS) of the acoustic signals and it generalizes our earlier results on classification of sustained musical sounds by higher order moments. An efficient `decorrelated matched filter' implementation is presented. The results show good sound classification statistics and a comparison to spectral matching methods is also discussed.
