  • Abstract
    A denoising method using computational auditory scene analysis (CASA) for a wearable stethoscope is proposed in this paper. The denoising method imitates human ears to analyze the ambient auditory scene so that it can separate the heart sound signal from unwanted ambient noise. Simulation results show that the method greatly improves the signal noise ratio of the heart sound signal after denoising.
