Wearable Auscultation Device Design

Auscultation is a treatment method frequently used by physicians in terms of giving general information about the body. By listening to the sounds of breathing, the physician can have a general knowledge of the patient's body. In addition, respiratory distress occurs in many diseases such as COPD and asthma. The development of biomedical device technology makes it faster and easier to diagnose and treat. In this study, an electronic equipment has been prepared for the auscultation process. It has 4 channels in the hardware, and two of the channels listen to the heart. Of the remaining 2 channels, one performs listening to the left and the other the right lung. A filter is designed for the heart, which decays between 20-500 Hz. Since breathing sounds can be heard at a wider frequency, a filter has been prepared that passes between 100-1000 Hz.
