The main aim of this book is to study the applications of signal processing techniques for human lung sounds. Telemedicine is an emerging topic in the field of healthcare. In developing countries like India where patients to doctor ratio is poor, telemedicine applications if applied effectively can immensely benefit the rural population. Due to recent advances in technology and widespread penetration of the cellular network, it is now possible to auscultate basic human body sounds and send the recording to the healthcare server for analysis and diagnosis report generation. This book is an attempt towards exploring some popular signal processing algorithms for the detection of abnormalities from human lung sound, especially the pediatric population.
