摘要

This paper introduces a new approach for extracting authentic heart and lung sounds when auscultated sounds contain interference and noise corruption. Unlike traditional signal separation methods that rely on frequency band separation or statistical independence, this methodology utilizes the unique feature of time-split stages in breath and cardiac cycles. By reconfiguring signal transmission channels during different phases of breath and heart cycles, this technique is capable of identifying channel dynamics in real time, removing noise effectively, and separating heart and lung sounds. Consequently, computer-assisted analysis and diagnosis of heart and lung sounds can become more accurate and reliable. Applications of this technique to wheeze diagnosis are discussed.
