Electronic esophageal stethoscope
2014 40th Annual Northeast Bioengineering Conference (NEBEC), 2014The purpose of this project is to design and produce an electronic esophageal stethoscope to be used by anesthesiologists during operations. The device currently in use relies heavily on the interpretation of the user. With all the background noise in an operating room, it becomes difficult for the user to differentiate every sound that is received ...

Electronic Stethoscope Design, Prototyping and Testing
IEEE EUROCON 2019 -18th International Conference on Smart Technologies, 2019The design, prototyping and testing of an electronic stethoscope, to auscultate internal body sounds is presented. The microphone used is an air pressure transducer. An active, 4th order, Butterworth band-pass filter is implemented with a 1 dB ripple in the passband.

Development of an Electronic Stethoscope
2015This paper presents the development of an electronic stethoscope which acquires auscultation results and transfers them to the computer where they can be immediately processed, analyzed, and replayed. The prototype based on the redesign of already existing stethoscope supplemented with data acquisition element (electret microphone connected to the ...

Headset for electronic stethoscope
The Journal of the Acoustical Society of America, 1997The headset comprises left and right elongate ear pieces having respective first ends to receive ear tips and respective, interconnected second ends. Each ear piece includes a one-piece elongate body made of flexible and resilient material and curved outwardly to skirt round the user's head when the ear tips are applied to a user's ears.

Electronic stethoscope system and method
The Journal of the Acoustical Society of America, 1989A microprocessor based sound enhancement system in which frequencies outside of the auditory range of the human ear are translated into sound within the auditory range by translating each frequency component of the entire frequency spectrum of the input signal by a time scale compression factor.

Acoustics of Electronic Stethoscopes for Health Professionals
American Journal of AudiologyPurpose: Commercially available electronic stethoscopes for auscultation often report amplification levels and may or may not publish amplitude–frequency (spectral) response curves. Additional data may be helpful to consumers who use stethoscopes in less-than-ideal listening environments or have hearing loss ...

A High-Fidelity Electronic Stethoscope
JAMA: The Journal of the American Medical Association, 1971To the Editor.— Electronic stethoscopes have not achieved widespread popularity, despite their increasing compactness, because of distortion and high background noise. Physicians complain of the need to reeducate their ears to interpret the new and unfamiliar sounds.
