摘要
An electronic stethoscope emulates the frequency response of a standard acoustical stethoscope in both bell and diaphragm modes, while providing additional features attainable only with an electronic stethoscope, such as signal amplification, noise reduction, wider bandwith, and mode selection. The electronic stethoscope includes spectrally separate idealized diaphragm and idealized bell modes. The idealized diaphragm mode and the idealized bell mode each include emphasized passbands and de-emphasized passbands. The emphasized passbands are spectrally separate. In addition, the electronic stethoscope also includes a wideband mode, which permits the user to hear high frequency sounds such as those associated with mechanical heart valves, lung sounds, and the like.
