摘要： A digital electronic stethoscope includes an acoustic sensor assembly that includes a body sensor portion and an ambient sensor portion, the body sensor portion being configured to make acoustically coupled contact with a subject while the ambient sensor portion is configured to face away from the body sensor portion so as to capture environmental noise proximate the body sensor portion; a signal processor and data storage system configured to communicate with the acoustic sensor assembly so as to receive detection signals therefrom, the detection signals including an auscultation signal comprising body target sound and a noise signal; and an output device configured to communicate with the signal processor and data storage system to provide at least one of an output signal or information derived from the output signal. The signal processor and data storage system includes a noise reduction system that removes both stationary noise and non-stationary noise from the detection signal to provide a clean auscultation signal substantially free of distortions. The signal processor and data storage system further includes an auscultation sound classification system configured to receive the clean auscultation signal and provide a classification thereof as at least one of a normal breath sound or an abnormal breath sound.

摘要： An electronic stethoscope includes an acoustic sensor assembly having a plurality of microphones arranged in an acoustic coupler to provide a plurality of pick-up signals. The electronic stethoscope also includes a detection system to communicate with the acoustic sensor assembly and to combine the plurality of pick-up signals to provide a detection signal. The electronic stethoscope also includes an output system to communicate with the detection system. The acoustic coupler uses a compliant material that forms an acoustically tight seal with a body under observation.
