Prototype electronic stethoscope vs conventional stethoscope for auscultation of heart sounds
Journal of Medical Engineering & Technology, 2014In an effort to decrease the spread of hospital-acquired infections, many hospitals currently use disposable plastic stethoscopes in patient rooms. As an alternative, this study examines a prototype electronic stethoscope that does not break the isolation barrier between clinician and patient and may also improve the diagnostic accuracy of the ...

Design and development of an electronic stethoscope
2017 Internet Technologies and Applications (ITA), 2017This 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
