Wavelet-based denoising method for real phonocardiography signal recorded by mobile devices in noisy environment
We show that the noise occurring during PCG signals measure has variable character. We adapt a wavelet denoising algorithm for the filtration of real PCG signal. The algorithm denoise PCG signals recorded in noisy environments by mobile devices. The performance of the algorithm was also tested on pathological heart sounds.
