原始语种摘要: The problem of isolating breath and cardiac sounds in the total signal registered on a human thorax has been of interest to physicians and researchers in the last two decades. Many algorithms have been developed to address this issue. In this paper we propose a new technique for isolating respiratory sound from a combined signal registered on the chest wall. The method is based on a hybrid algorithm using a mathematical morphological approach and spectral subtraction technique. This approach has been tested both on the artificially simulated data and on real auscultative sounds. Evaluation of efficiency by means of auditory, visual and numerical analysis shown that the proposed strategy is a promising alternative to existing technologies of separation of auscultative signals on its...
