ABSTRACT:
An electronically amplified, recording, stereophonic stethoscope, EARSS, utilizes binaural phase effect from two probes held in one chestpiece with amplifier. Skin contacts in probes are small, to localize, pliable, to fit body curves, shaped for acoustic amplification, spread for wide pickup. Connecting tubes are flexible, with dimensions and properties that protect, isolate, reinforce and adapt skin contacts to microphones. Adapters for multiple stereophones, listeners, recorders, videocameras and imaging of induced sound, facilitate teaching, consultation and sharing with patients. More sensitive and specific detection and recognition of diseases and functions stimulate more careful auscultation by physicians, new uses and tests, and increased lay use of a classic professional symbol.
