Identification of Respiratory Diseases using Peak Energy Analysis of Acoustic Cough

Background and Objectives Cough is a common symptom of respiratory diseases and change in the cough sound can reflect a pathological condition in the lungs. Recent advancement on the analysis of the cough sound has suggested that it has the potential to be used as a non-invasive marker for screening respiratory conditions, such as Asthma, Chronic Pulmonary Obstructive Disease (COPD), Interstitial Lung Disease (ILD) and Bronchiectasis. The energy envelope is distinguishable for normal subjects versus subjects with respiratory conditions. Peak analysis of the energy envelope helps in quantifying the feature variation for these conditions.
