要約

A problem on sound propagation in traditional medical stethoscope is solved on the basis of analytical method of partial domains accounting for air viscosity. An expression for stethoscope's transmission function is obtained. The influence of geometric dimensions of stethoscope elements on its transmission function is investigated in details. Comparative analysis of theoretical and experimental data is carried out. Initial data for rational design of stethoscopes are obtained.
