Abstract

The invention herein discloses a multimedia acoustic stethoscope that has look and feel of a conventional acoustic stethoscope but allows a medical practitioner to transmit sounds from stethoscope to a recording device, and to transmit recorded sound back to the stethoscope for playback. The recording device could be a tape recorder, a digital recorder, a personal computer, a pocket PC, a handheld PC, a tablet PC, or a PDA. The data can be transmitted via a wire or wirelessly, for example using Bluetooth wireless technology.
