Heart sound is one of the significant bio-signals to diagnose certain cardiac anomalies. Aiming to provide an automatic heart sounds analysis to medical professional, we present a method of heart sound segmentation based on simplicity and strength. The method has two phases: first phase identifies the timings of S1 and S2 sounds’ start and end using simplicity and strength in wavelet domain, and the second phase determines the S1 and S2 using high frequency information. The method incorporates an adaptive approach for thresholding simplicity and strength profile in timings of the sound components detection, as well as main heart sounds components S1 and S2 in presence of abnormal sound, so called murmur. A comparable result to the state-of-the-art methods has been yielded.
