VISUALISATION OF HEART SOUND

HEART SOUND ACQUISITION

Heart sound acquisition refers to the process of recording the sounds produced by the heart during its regular operation. These sounds, known as heartbeats, typically consist of two distinct tones: the lub (S1) and dub (S2), which correspond to the closing of heart valves. These sounds are crucial for assessing heart function and diagnosing various cardiac conditions such as murmurs, arrhythmias, and other abnormalities. 

WHY HEART SOUND ACQUISITION MATTERS ?

Heart sound acquisition is the first step in analyzing heart function. Without clear, high-quality recordings, it becomes difficult to detect subtle abnormalities that may indicate early signs of heart disease. By capturing these sounds electronically, it is possible to analyze them using advanced algorithms, helping to detect issues that might be missed during a manual check-up with a traditional stethoscope.

This data also forms the basis for further steps in the project, including signal preprocessing and feature extraction, which are essential for diagnosing heart conditions automatically.
