An interactive computer analysis of the aortic ejection click and first heart sound
… and frequency domains from computer processed phonocardiogram data obtained from 13 valvar aortic stenosis patients and 6 normal ones. The interactive FOBTRAI program developed was capable of the following: (1) computing averages, aligned averages, power spectra of selected segments, …

A Comparison of Wavelet and Simplicity-Based Heart Sound and Murmur Segmentation Methods
… heart sounds and murmurs in digitized phonocardiogram audio files. Two separate segmentation techniques based on the discrete wavelet transform (DWT) and the simplicity transform are integrated into a MATLAB software system that is capable of automatically detecting and classifying …

Development of novel optical sensing-based digital stethoscopes and deep learning-based heart sound denoising algorithms
… produced by this activity can be recorded as a phonocardiogram (PCG) using a digital stethoscope. Cardiac auscultation using a digital stethoscope is an important method for diagnosis of cardiovascular diseases (CVDs), such as valvular heart diseases, heart failure, and congenital heart defects …

Akustisches Synchronisationsverfahren für die Magnetresonanztomographie
… of the MR-stethoscope towards capturing fetal phonocardiograms at (ultra)high magnetic fields. Further investigation is anticipated to ensure reliable performance of the acoustic synchronization approach in patients with heart or valvular diseases. Valvular defects need not be prohibitive for …
