In a local stethoscope unit, acoustic auscultation sounds picked up by the stethoscope chest piece assembly of a local stethoscope unit are converted to analog electrical signals and then converted to digital signals. The digital signals are conveyed to a data communications system, having data communications device and a data communication channel. The digital signals are transmitted over the digital communications system to a remote stethoscope receiving unit. The remote stethoscope unit converts the digital signals back to the original analog signals suitable for listening.
