During the physiological activities of some organs of human body, some sounds are generated, such as heart sound of heartbeat, respiratory sound of air flowing in respiratory tract, bowel sound of intestinal peristalsis and the like. These sounds may be collectively referred to as body sounds, which are called physiological body sounds when the organ structure and function are normal, and pathological body sounds when the organ structure and function are changed. Therefore, by monitoring the changes of these body sounds, the health condition of the corresponding organ structure functions of the human body can be known. Auscultation therefore becomes an important component of the physical examination performed by clinicians for patients.
Currently, the auscultation tool commonly used by clinicians is a stethoscope. The traditional stethoscope was invented in 1816 by the french physician Ren Laennec raney.
