Non-Contact Heart Sound Measurement Using Independent Component Analysis

open access: yesIEEE Access, 2022
A non-contact heart sound measurement method using independent component analysis (ICA) was successfully developed, and the measured heart sound was quantitatively evaluated with the signal-to-noise ratio (SNR). There have been recent developments in the

Classification of Heart Sounds Using Convolutional Neural Network

open access: yesApplied Sciences, 2020
Heart sounds play an important role in the diagnosis of cardiac conditions. Due to the low signal-to-noise ratio (SNR), it is problematic and time-consuming for experts to discriminate different kinds of heart sounds.
