Performance Evolution of Heart Sound Information Retrieval System in Multicore Environment

The most difficult and problematic task for cardiology specialists is the interpretetation of heart sounds. It requires special skill and clinical experience along with detailed and expensive tests. However, while detection of heart disease heart sound is proffered for the first step of diagnosis . Recently, many Computer aided auscultation has emerged as a cost-effective technique to analyze and interpret the heart sounds. In this study we propose a feasible technique for developing a heartbeat sound information retrieval system using sound wave matching useful towards automated heart disease detection. The feasibility of these text based retrieval approaches are shown from retrieval experiments with around 23 digital heart sound recordings which are repeatedly matched with the database heart sound and the corresponding disease is given. The sound information retrieval is carried out parallel for better performance. Keywords— Heart sounds, auscultation, MIDI, pitch tracking
