In combat casualty and civilian environments, an unmet need exists for a stethoscope that can hear heart and especially breathing sounds while inside helicopters, fixed-wing aircraft, or ambulances where noise levels preclude auscultation with standard stethoscopes. Without this capability, patients can suffer from unidentified collapsed lungs or loss of intubation integrity with the threat of ...

Cardiac auscultation is the examination of heart by listening to sound produced through a stethoscope. Heart sounds can provide information about functioning valve condition as well structural abnormalities heart. However, it needs intensive training for mastering. The objective work was develop an algorithm signal classification applied computer-assisted digital in order identify pathological ...

T HERE are no reliable acoustical data to aid physicians in their selection or use of a stethoscope. Yet, the sole medical utility of any stethoscope is derived from its acoustical performance. It is the purpose of this paper to provide clinicians with objective acoustical performance data on intact and current stethoscopes. Frederick and Dodge' first recognized that the stethoscope was deservi...

Training in cardiac auscultation is a core element of undergraduate teaching but recent studies have documented a remarkable decline in auscultatory skills. Therefore there is an interest in new ways to teach cardiac auscultation. In analogy to phonocardiography, an electronic system for simultaneous auscultation and visualisation of murmurs was sought. For this purpose, an electronic stethosco...
