Where are s1 and s2 heart sounds heard?
The intensity of S1 depends upon: the position of the AV valves at the onset of ventricular systole, the structure of the leaflets themselves, and the rate of pressure rise in the ventricle. Normally, S1 is louder than S2 at the apex, and softer than S2 at the base of the heart.
