“Removal of Heart Sound from Lung Sound using LabVIEW 8.6”

By R. M. Potdar and Nishi Shahnaj Haider

Abstract

Abstract- It has been found that while analyzing Lung sound using stethoscope Heart sounds are intermixed with Lung sound. Heart sound interference with lung sound is one of major problem, as actually it affects the potential of lung sound which often effects the proper detection and diagnosis of disease. The aim of this proposed work is to implement a VI which can detect and separate out the HS segments from LS sound using Advanced Signal processing toolkit of LabVIEW 8.6. The method we will use is the multiresolution analysis of the wavelet approximation coefficients of the original signal to detect HS-included segments. Once the HS segments are identified, the method after detection removes them from the wavelet coefficients and estimates the created gaps by using TSA ARMA modeling and prediction
