Analytical method for estimation of audio properties of stethoscopes

Acoustic bulletin, Vol. 3 ¹ 3, (2000) p.10-16
The problem on sound propagation in traditional medical stethoscope is solved on base of analytical method of partial domains considering the air viscosity, and the expression for its transmisson function is obtained. The influence of geometrical dimensions of the stethoscope elements on its transmission function is investigated in details. Comparative analyses for theoretical and experimental data is carried out. Initial data for rational design of stetoscopes are received.
KEY WORDS:
