چکیده

During the COVID-19 outbreak, auscultation of heart and lung sounds has played an important role in comprehensive diagnosis real-time monitoring confirmed cases. With clinicians wearing protective clothing isolation wards, a potato chip tube stethoscope, which is secure flexible substitute for conventional been used by Chinese medical workers first-line treatment COVID-19. In this study, optimal design simple cylindrical stethoscope proposed based on fundamental theory acoustic waveguides. Analyses cutoff frequency, sound power transmission coefficient, wave propagation uniform lossless provide theoretical guidance selecting geometric parameters stethoscope. A basic investigation into auscultatory performances original with dimensions was conducted both semi-anechoic chamber quiet laboratory. Both experimental results front-line doctors' clinical feedback endorse optimization.
