资料介绍

为获得定量化的听诊结果,设计了一种基于听诊音频谱分析的数字听诊系统。该数字听诊系统由硅麦克风传感器接收人体器官发出的声音,经过运算放大、滤波和模数转换,将模拟信号转换为数字信号传送至专用集成电路芯片进行后续处理,再由终端设备输出详细、准确的听诊音频谱分析结果,达到帮助精确记录和科学分析听诊结果的目的。

A digital auscultation system based on auscultation audio spectrum analysis has been designed to provide quantitative evaluation of auscultation results. This auscultation system receives sound signals from human body organs using the embedded silicon microphone sensor first. After processed by the operational amplifier,the filter circuit and the analog to digital converter,the original analog signals are converted to digital ones and sent to the application specific integrated circuit module for further processing. The final device output the detailed and accurate auscultation audio spectrum for auxiliary diagnosis. The proposed digital auscultation system provides convenience for recording and analyzing the auscultation results.
