Noise Control of Heart by Means of a Mobile Phone

The book 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 mobile phones. 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. For this purpose, obtained noise estimates are taken as symptoms and, by training, their combinations are used to form the set of reference symptoms and the bank of set of symptoms of both disease state and healthy state of the phone user, who after a certain training period can use the phone as a device for noise control of his heart and lungs health. Duplication of monitoring with application of informative attributes obtained by means of technologies for robust correlation, spectral and position-binary analysis provides validity of results.
