ABSTRACT:
A mechanical system for reducing unwanted vibration of a stethoscope chestpiece, which reduces the signal components of the chestpiece output due to sources of vibration other than internal physiologic processes within the patient's body. The system includes a compliance, a mass, and a mechanical resistance element, which together increase transmission loss of external sources of vibration between their source and the chestpiece transducer. Methods of using such a system are also disclosed.
