S1: The first heart sound, a low-pitched sound caused by the closing of the mitral and tricuspid valve. S2: The secound heart sound, caused by closing of the aortic and pulmonary valve. S3: An extra heart sound. S3 is a ventricular gallop, a low-pitched sound that can follow S2.

WebDefinition. Heart sounds are discrete bursts of auditory vibrations of varying intensity (loudness), frequency (pitch), quality, and duration. The first heart sound (S 1) is composed of several high-frequency components; only the first two are normally audible.These two sets of audible vibrations are temporally related to closure of the mitral and tricuspid valves.
