NOISE ANALYSIS OF HEART AND LUNGS SOUNDS BY MEANS OF LAPTOPS AND SMARTPHONES
The paper offers noise technologies for monitoring of the beginning of cardiovascular and respiratory diseases, considering the possibility of listening to the sounds of heart and lungs by means of microphones of laptops and smartphones. Such estimates of the sounds of heart and lungs as noise variance, value of noise correlation, cross-correlation function between the useful signal and the noise and coefficient of correlation are used as informative attributes for identification of the beginning of the latent period of diseases.
Keywords: Noise analysis, noise variance, value of noise correlation, cross-correlation function, heart diseases
