This book particularly presents basic and novel theories with practical examples of the two main topics: of Digital Processing of Acoustic Signals, such as : Speech and Heart Sounds. Namely : - Digital Room Acoustics Equalization, because in many sound reproduction systems the degradation quality of the speech signal is mainly caused by the room effect, and- Automatic Heart Sounds Segmentation, as it is an essential phase before objective analysis and diagnosis.Homomorphic standard method and its modified version for equalizing room acoustics effects on the speech signal are presented. An...
