HIGHLIGHTS

SUMMARY

Hadjileontiadis and Panas and Liu et_al used wavelet transform techniques to denoise heart sounds from lung signals and, conversely, filter out lung sounds from heart sounds. In, EMD was used to separate heart sounds from lung signals;, EMD was used to capture heart murmurs; and, EMD was used to segment and capture the underlying heart sounds (S1, S2). As the two processed heart/lung signals and noise signals need subquencies of the two processed processed heart/lung signals and noise signals need subquenciesthe of sound. sound. Two microphones were used in Models 1~2 . . .
