Explanation:
Two normal heart sounds come from valve closures. The first sound marks the closure of the AV valves at the start of ventricular systole, while the second marks the closure of the semilunar valves at the end of systole. The first sound is typically lower in pitch and longer, and it is usually softer to hear, especially at the apex. The second sound is higher in pitch and shorter, often perceived as louder and crisper, particularly at the base. Therefore, in most cases, the first heart sound is softer than the second.
