Abstract
In this paper, we developed a digital auscultation system which provides a useful tool for users to measure the heart sounds and to see the waveform of sounds such as phonocardiogram. This system includes an ARM-based digital stethoscope with a USB port for data transmission and a PC-based graphic user interface for waveform and heart rate display and data recording. The functions of this digital stethoscope include play back, filtering, volume adjustment of sounds, and data transmission. Besides, the digital stethoscope can measure the sounds and then forward the data to the PC via the USB interface. On the PC, user can easy to see the waveform of sounds on the graphic user interface. For heart sounds measurement, we also implemented a heart rate detection algorithm so that heart rate can also be shown on the graphic user interface. This system would be useful for aiding the auscultation diagnosis and telemedicine applications.
