Abstract
This paper presents the development of an electronic stethoscope which acquires auscultation results and transfers them to the computer where they can be immediately processed, analyzed, and replayed. The prototype based on the redesign of already existing stethoscope supplemented with data acquisition element (electret microphone connected to the computer sound card) as well as dedicated software for data acquisition and processing is presented. The developed device has an advantage over a commercial product used for the comparison, i.e., it allows for simultaneous auscultation and monitoring the recorded signal with time–amplitude plot or spectrogram as well as enables sound acquisition with much higher sampling frequency, which can be essential in detailed heart and lung analyses.
