What is the difference between systolic and diastolic pressure? What makes the “dubb” sound? These valves are deep inside the heart and are between the upper (atrial) and lower (ventricular) chambers. ; Valve regurgitation – a valve that does not close completely, allowing backward flow (a "leaky" valve). The 'lubb dubb' heart sounds heard through a stethoscope are the sounds of the atrioventricular (AV) valves and semilunar (SL) valves opening and closing. you need to get through it to get the real experience. The second part pf the lubb-dubb (the second heart tone or S2) is caused by the closure of the aortic and pulmonary valves at the end of ventricular systole. This is particularly important for differentiating between systolic and diastolic murmurs (covered separately here), as well as identifying any pathological heart sounds. S3 is the sound of blood sloshing around in … I learned from school that both the tricuspid and Mitral valve close at the same time thus creating the Lub sound and the bicuspid and aortic close at the same time thus creating the dub sound.
