Heart Sounds. Heart sounds are generated by the turbulance created by blood flowing through the heart, specifically when the heart valves close. Normal heart sounds can be characterized by a lub dub that occurs with a heart beat. The first heart sound (lub) occurs when the atrioventricular (AV) valves close and the second heart sound (dub) is heard when the semilunar valves close.
The closing of the mitral valve and the tricuspid valve constitutes the first heart sound (S1), which can be heard with a stethoscope. It is not the valve closure itself which produces the sound but the sudden cessation of blood flow, when the mitral and tricuspid valves close.
