AN EXPERIMENTAL ELECTRONIC STETHOSCOPE FOR AIRCRAFT USE.

Abstract

An experimental electronic stethoscope for use aboard aeromedical evacuation flights and on flight lines was developed. Preliminary evaluation has indicated that such an instrument is both feasible and useful aboard aeromedical-evacuation aircraft and in patient staging areas on the flight line. Utilization of a noise-shielded pickup and earphones mounted in a noise-protection earmuff, plus the use of appropriate filter circuits, substantially excludes environmental noise while enhancing the audibility of desired sounds.
