| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | While heart disease is one of the three major diseases, only well-qualified doctors can evaluate phono- cardiographic signals. However, phonocardiographic signals are not always used in healthcare because only a few professionals are experts in evaluating phonocardiographic signals. This calls for an easily available system that can automatically diagnose phonocardiographic signals. But, everyday noises such as lung and breath sounds, environ- mental noises, and blood flow noises may contaminate these signals and hinder analysis. When recording in a room, suppression is required as these signals are heavily contaminated by noise from various sources. In this study, we examine the appropriate parameters of various wavelet functions and multiplicative threshold rescaling for various phonocardiographic signals, and compare between the proposed method and spectral subtraction in diagnose rate. |
