A simple lung sound enhancement for automatic identification of lung pathologies

Auscultation or lung sound analysis depends on the familiarity of the physician on detecting sound patterns. However, typical environment for auscultation are performed in rooms susceptible to different sounds such as vocal sound, ventilation machines and ambient noise, which may impede the subjecti...
