一种人体生理声音分析系统的设计

Design of a human physiological sound analysis system

介绍了一种人体生理声音信号采集／分析系统的软、硬件设计：系统应用PC机声卡作为数据采集卡，在MATLAB环境中，通过在图形窗口中加入菜单及控制，实现了直接对窗口对象的操作；建立了一个实时人体生理声音信号采集／分析处理平台。指出其具有实现简单、性价比和灵活度比较高的优点。

The paper introduces software and hardware design for a human physiological sound acquisition/analysis system, which is based on PC sound card and can make the real time physiological sound acquisition/analysis. The software can manage the objects by adding menus and controls to MATLAB figure windows; a platform is built for real time physiological sound analysis in MATLAB environment. The system has the characteristics of simple realization, high cost performance and high flexibility.
