Headset for electronic stethoscope

The Journal of the Acoustical Society of America, 1997
The 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, 1989
A 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.

Electronic stethoscope for detecting heart abnormalities in athletes

2020 21st International Arab Conference on Information Technology (ACIT), 2020
Cardiovascular diseases (CVD) are one of the main causes of death and disability in most countries of the world. As part of the fight against high morbidity, there is a clear shift in the global health paradigm towards active prevention and prevention, rather than treatment, of diseases, and a desire to reduce inpatient care in favor of outpatient ...

Design and development of an electronic stethoscope

2017 Internet Technologies and Applications (ITA), 2017
This paper discusses the design of an electronic stethoscope which is used to listen to the heart and lung sounds. The sounds are captured from the surface of the skin, after which they are filtered and amplified to enable the signal level to exceed the audible threshold. A loudspeaker is used to clearly listen to the processed signals. The signals are

An electronic stethoscope with diagnosis capability

Proceedings of the 33rd Southeastern Symposium on System Theory (Cat. No.01EX460), 2002
A means of analyzing acoustic heart sounds is described. The system analyzes heart sound data, isolating key features of the heartbeat signatures to produce a list of possible diagnoses. The system has six major components: heart beat extraction, segmentation of the heart sound cycle, extraction of murmur data, time-frequency analysis of murmurs ...
