The familiar 'lub-dub' sound of the heartbeat is caused by the rhythmic closing of the heart valves as blood is pumped in and out of the chambers.

What is the difference between heartbeat and heart sound?

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut.

What sound does a heartbeat sound like?

Two distinguishable sounds can be heard during the cycle of the beating heart when listened to with a stethoscope. The heart sounds are usually described as a lup-dup sound. These sounds are due to the closing of the valves of the heart. Unusual heart sounds are called murmurs.
