In this study, we first developed a prototype of auscultation cloth which is easy to wear and to collect good quality heart sound even by general users. The heart sounds both from the normal persons and heart disease patients have been collected by using the auscultation wear. The collected sound signals including their feature parameters obtained by analysis have been made in the heart disease sound database. To improve the resolution both in time and frequency domains analysis, a novel time-frequency analysis, called as Frequency Slice Wavelet Transform(FSWT), was proposed. By using this method, it is possible to extract more accurate heart sound feature parameters both in the frequency and time domains. By applying the data clustering method(SVM) to these parameters, the results shown that the heart disease can be identified with high accuracy.

在这项研究中，我们首先开发了一种听诊布的原型，它易于佩戴，即使是普通用户也能收集到高质量的心音。用听诊器采集了正常人和心脏病患者的心音信号。将采集到的声音信号及其分析得到的特征参数存入心脏病声音数据库。为了提高信号的时频分辨率，提出了一种新的时频分析方法--频率切片小波变换。该方法可以在时域和频域上提取出更准确的心音特征参数。通过应用数据聚类方法（SVM）对这些参数，结果表明，心脏病可以识别与高精度。
