Abstract: In one aspect, an auscultation system utilizes a digital filter to obtain a sound profile similar to a sound profile of a mechanical stethoscope. In another aspect, an auscultation system utilizes a digital filter to provide diagnostic filtering. In yet another aspect, an auscultation system utilizes a digital filter to compensate for a characteristic frequency response of a headset.

Abstract translation: 在一个方面，听诊系统利用数字滤波器来获得类似于机械听诊器的声音轮廓的声音简档。 在另一方面，听诊系统利用数字滤波器来提供诊断滤波。 在另一方面，听诊系统利用数字滤波器来补偿耳机的特征频率响应。

Abstract: An electronic stethoscope includes a housing configured for hand-held manipulation, a transducer supported by the housing and configured to sense auscultation signals at a first location, and a headset coupled to the housing and configured to deliver audio corresponding to the auscultation signals through earpieces on the headset. The electronic stethoscope further includes a processor disposed in the housing and configured to convert the auscultation signals to first digital signals representative of the auscultation signals and to wirelessly transmit the first digital signals from the electronic stethoscope via a secure digital network to a second location such that the audio corresponding to the auscultation signals is provided to headsets of one or more additional electronic stethoscopes at the second location in substantial real time with the sensing of the auscultation sounds at the first location.
