• A number of investigators" have recently studied liow heart sounds and murmurs spread through the various tissues of men and dogs. For instance, Magri et al. studied the transmission of heart sounds over the surface of the exposed human heart. Ken and Harp, Iverr et al. and ourselves"' investigated the velocity and the damping with which sound is transmitted through arteries, and showed that ...

This paper presents the design and testing of a wireless sensor system developed using a Microchip PICDEM developer kit to acquire and monitor human heart sounds for phonocardiography applications. This system can serve as a cost-effective option to the recent developments in wireless phonocardiography sensors that have primarily focused on Bluetooth technology. This wireless sensor system has ...

Heart sounds classification plays an important role in cardiovascular disease detection. Currently, deep learning methods for heart sound with heavy parameters consumption cannot be deployed environments limited memory and computational budgets. Besides, de-noising of signals (HSSs) can affect accuracy classification, because erroneous removal meaningful components may lead to distortion. In th...

A new method and application is proposed to characterize intensity and pitch of human heart sounds and murmurs. Using recorded heart sounds from the library of one of the authors, a visual map of heart sound energy was established. Both normal and abnormal heart sound recordings were studied. Representation is based on Wigner-Ville joint time-frequency transformations. The proposed methodology ...
