Analysis and classification of heart sounds with spectral analysis

Abstract

Hearing the heart sounds is an important clinical examination for all doctors, and it is used to detect the possible health problems of the heart, and thus training on this is considered an important element in the field of medical diagnosis, and in light of the developments of the rapid technology and the emergence of the computerized devices, the analysis of the frequency of the heart sounds has become a distinctive sign of the heart activities in the activities of the heart, this paper is an analysis and classification of natural and abnormal hearts, in order to determine the advantages that Through which some heart disease can be judged. The treatment of the heart sounds was carried out using ((Matlab Simulink, where special frequency spectra was calculated using some sports analysis models, and through this it was reached that when comparing regular and abnormal sounds, natural signals features appear from high energy levels, while low energy levels dominate other frequency components, the analysis model used achieved a accuracy rate of 90% by using the evaluation methods used in the processing processing
