Abstract: The present invention is directed to an assembly used for modifying an ordinary acoustic stethoscope to an electronically amplified stethoscope. This assembly is mechanically married to a conventional stethoscope's tubular structure. An earpiece unit which replaces the standard earpiece on the earpiece-end of the ordinary acoustic stethoscope, is positioned so the standard air column response of any ordinary acoustic stethoscope is picked up by a microphone placed inside this special earpiece unit, thus capturing the acoustic output of the parent stethoscope and transmitting it back to a preamplifier/amplifier and frequency equalizer unit (graphic equalizer). The electronic signal is then directed to a speaker located in the special earpiece unit for monitoring by the operator, or alternatively, such signal is directed to a number of other remote units for the purpose of facilitating teaching and learning.
