1. An electronic stethoscopy system comprising a plurality of stethoscopes and a remote unit which communicates with said plurality of stethoscopes, each stethoscope also communicating with each other stethoscope and including:
- a pick-up circuit including a microphone for transforming detected sound into an electric signal, an amplifier for amplifying said electric signal and filters for removing noise in said electric signal;
transmitting and receiving circuits including an emphasizer receiving, via a first switch, the amplified and filtered signal from said pick-up circuit for emphasizing high frequencies, a modulator for modulating the emphasized signal for transmission, a demodulator for demodulating an input signal received from the remote unit or another stethoscope, and a deemphasizer for deemphasizing high frequencies in the demodulated signal; and
a binaural earpiece having speakers selectively connected, via a second switch, to the amplified and filtered signal from said pick-up circuit or to the deemphasized signal from said receiving circuit, wherein the detected sound from one stethoscope may be received by another stethoscope communicating therewith so as to enable co-listening by one or more users of said one and another stethoscopes.

Abstract
A diagnostic system comprising one or more stethoscopes and a diagnostic unit. Each stethoscope is used to pick up a sound, which is then transmitted in radio form via an antenna after amplification through an electric/audio transducer. The sound, after being received by the diagnostic unit, is compared in a computer for diagnosis of the symptoms. The result of the diagnosis is then transmitted through an antenna and received by the stethoscope for reference by its user.
