PCG signal recordings are so complex and non stationary signal, they are also affected by different kinds of noise the segmentation method followed by the time and frequency domain analysis characterization of some phonocardiogram (PCG) signals. The paper using the Discrete Wavelet Transform (DWT) in decomposition signal. In the segmentation technique, we calculate the signal to noise ratio and peak signal to noise ratio and energy of the details coefficients at each level and threshold it in order to detect the murmur of heart sound signals. The results of the method illustrate clearly the detection of the main components S1, S2, S3, S4 Pathological murmurs and the identification of the valves disease.
