An electronic stethoscope is judged better than conventional stethoscopes for anesthesia monitoring

Journal of Clinical Monitoring and Computing, 1986
A prototype electronic monitoring stethoscope was constructed from readily available, high-quality components. It consisted of a conventional precordial or esophageal probe connected to a microphone by a rubber adapter. The microphone was connected by lightweight wire to an amplifier and headphones.

Clinical Comparison of Acoustic and Electronic Stethoscopes and Design of a New Electronic Stethoscope

The American Journal of Cardiology, 1998
This clinical study was performed to evaluate the advantages and limitations of 3 acoustic stethoscopes and 3 electronic stethoscopes. It shows that it is possible to design a new electronic stethoscope by considering the advantages of both the acoustic and electronic stethoscopes.

Development of an Electronic Stethoscope Using Raspberry

2021 IEEE International Conference on Consumer Electronics-Taiwan (ICCE-TW), 2021
In this study, Raspberry Pi 3B was used to develop an electronic stethoscope by embedding a condenser microphone in the traditional stethoscope head to collect heart and lung sounds. The collected signals pass through amplification and filter circuits, and then the processed signals are transmitted to the Raspberry Pi through audio cables. In addition,

Electronic esophageal stethoscope

2014 40th Annual Northeast Bioengineering Conference (NEBEC), 2014
The 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, 2019
The 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.
