1. A medical device, comprising:
a case having a front surface that is configured to be brought into contact with a body of the living subject, wherein the front surface comprises a membrane which is configured to vibrate in response to acoustic waves emitted from the body;
a microphone which is contained in the case and configured to sense the acoustic waves emitted from the body and to output an acoustic signal in response thereto;
a proximity sensor which is configured to output a proximity signal indicative of contact between the front surface and the body;
at least one speaker configured to output audible sounds;
a motion sensor which is contained in the case and is configured to configured to sense the motion of the membrane and output a motion signal in response to the motion, and
processing circuitry which is configured to
receive the output proximity signal,
detect, in response to receiving the proximity signal, that the front surface is in contact with the body, and,
in response to the detected contact, process the acoustic signal so as to generate an audio output and to convey the audio output to the at least one speaker, and
process the motion signal in order to detect an infrasonic component of the acoustic waves;
wherein the proximity sensor comprises at least one emitter which is configured to emit optical radiation, including infrared radiation, toward the body, and a detector which is configured to sense the optical radiation reflected from the body,
wherein the proximity signal indicative of contact that is output to the processing circuitry is responsive to the reflected radiation sensed by the detector, and the processing circuitry is also configured to measure a level of oxygen saturation in blood of the subject responsively to the reflected radiation sensed by the detector.
