Reduction of Heart Sounds from Lung Sounds

Master Thesis

Research Areas


Lung sound signals are produced in the airways of a human being during inspiration and expiration cycles. The lung sound signals propagate through lung tissues in the parenchyma and can be recorded over the chest wall. An incessant noise source occurs due to heart sounds. This noise source severely contaminates the lung sound signal. For the analysis of lung sounds it necessary to reduce heart sounds.
