Stethoscope acoustics
… invaluable diagnostic tool. For over 200 years, stethoscopes have been used to listen to these sounds. Despite this, the physics of how stethoscopes work remain poorly understood. While the stethoscope itself is a simple device, its performance depends on how it is coupled to both the patient and …

Design, Characterization and Application of a Multiple Input Stethoscope Apparatus
… possible applications of a multiple transducer stethoscope apparatus were investigated. The multi-transducer sensor array design consists of five standard stethoscope diaphragms mounted to a rigid frame for a-priori knowledge of their relative spatial locations in the x-y plane, with compliant …

The Use of a Tuning Fork and Stethoscope Versus Clinical Fracture Testing in Assessing Possible Fractures
… of a possible fracture. The tuning fork and stethoscope method relied purely on a subjective assessment from the examiner. The purpose of the study was to determine if the use of a 128Hz tuning fork and stethoscope were effective evaluation tools in the assessment of possible fractures as …

The problem of the stethoscope: an enquiry, experimental and philosophical, into the properties of this instrument and the physics of auscultation
My interest in Stethoscopy dates back to the time when I first entered the class of Clinical Medicine. I had previously, while on war service, been interested in the propagation of sound in sea water, and finding that acoustics played so important a part in the diagnosis of pulmonary and cardiac …

Development of novel optical sensing-based digital stethoscopes and deep learning-based heart sound denoising algorithms
… of novel optical sensing-based digital stethoscopes and deep learning-based heart sound denoising algorithms. Cardiac auscultation is the act of listening non-invasively to the sounds of the heart. It provides insights into the mechanical activity of the heart, and the sounds produced by …

A data mining approach for acoustic diagnosis of cardiopulmonary disease
… listening skills make diagnosing a patient via stethoscope based auscultation problematic. Doctors have now turned to more advanced devices such as x-rays and computed tomography (CT) scans to make diagnoses. However, recent advances in lung sound analysis techniques allow for the auscultation …

Development of Ionic Polymer Metallic Composites as sensors
… toward the development of an electronic stethoscope for digital auscultation. The sensors were characterized both geometrically and electrically to determine their effectiveness in resolving a signal from sub 1 Hz to 2 kHz. Impedance spectroscopy was used to interrogate the sensing …

Automated auscultation : using acoustic features to diagnose mitral valve prolapse
… physician listens to the heart using a stethoscope to assess the condition of the heart muscle and valves. This process, termed cardiac auscultation, is the primary means of diagnosing cardiac disorders, the most common of which is Mitral Valve Prolapse (MVP). Yet, the practice of …

MIT Automated Auscultation System
… annual exam, the primary care physician uses a stethoscope to listen for cardiac abnormalities. This approach is non-invasive, inexpensive, and fast. It is also highly unreliable. Over 80% of the people referred to cardiologists as suffering from the most commonly diagnosed condition, mitral …

Quantifying crackles in the lung of smoking and non-smoking young adults
… these differences, if present, using a digital stethoscope and computer aided lung sound analysis (CALSA). Sixty male subjects (30 smokers and 30 non-smokers) with an average age of 26.6 years (SD ± 4.7) were recruited, drawn from students at the University of Southampton in the United Kingdom. …

Carotid collar : a device for auscultory detection of carotid artery stenosis
… stroke. This device consists of three electronic stethoscopes that record heart and carotid artery sounds and an electrocardiograph. A software application, ccrec, was written to make the device easy to use by displaying real-time waveforms and storing the recorded signals in files for later …

Comparability of an innovative Doppler ultrasound fetal heart rate monitor to a pinard fetal stethoscope using cardiotocography as a standard to assess the fetal heart rate in singleton pregnancies during labour at Mowbray Maternity Hospital
… that accompany the use of a Pinard Fetal Stethoscope (PFS) which include user-dependence and lack of evidence based standardisation in taking measurements with it. Although intermittent fetal heart monitoring is as effective as continuous electronic monitoring in low risk labours (Banta DH …

Bayesian models for screening and diagnosis of pulmonary disease
… a mobile toolkit that consists of an electronic stethoscope, an augmented reality peak flow meter, and an electronic questionnaire. Previously, logistic regression has been used for modeling pulmonary disease.

A framework for automated heart and lung sound analysis using a mobile telemedicine platform
… performance under field conditions, a low-cost stethoscope attachment is constructed and data is collected using a mobile phone. Finally, a telemedicine infrastructure and work-flow is described, in which these algorithms can be deployed and trained in a large-scale deployment.

Assisted auscultation : creation and visualization of high dimensional feature spaces for the detection of mitral regurgitation
… auscultation, listening to the heart using a stethoscope, often constitutes the first step in detection of common heart problems. Unfortunately, primary care physicians, who perform this initial screening, often lack the experience to correctly evaluate what they hear. False referrals are …

Classification of Auscultation Sounds Using a Smart System
… Lung sound classification and using a digital stethoscope can be used to provide an immediate diagnostic for respiratory-related diseases. The International Conference on Biomedical and Health Informatics (ICBHI) created a sound data base in 2017 that is annotated with a classification of the …
