During inspiration: The second sound (S2) is made of two component sounds: Aortic valve closure (A2) which happens first. Pulmonic valve closure (P2) which happens second. A2 is heard widely all over the chest. So when you hear 'S2' at the mitral area, you are really hearing A2. Normally, P2 is soft and only heard at the pulmonic region (left ...

Their quality, however, does surpass that of M4A and MP3.
The first heart sound, or S 1, forms the "lub" of "lub-dub" and is composed of components M 1 (mitral valve closure) and T 1 (tricuspid valve closure). Normally M 1 precedes T 1 slightly. ... Pulmonary S2 (P2) will be accentuated (loud P2) in pulmonary hypertension and pulmonary embolism. S2 becomes softer in aortic stenosis.

Heart sounds. Two normally heard heart sounds are the first heart sound (S1) and second heart sound (S2). Second heart sound has two components - aortic (A2) and pulmonary (P2). Normal A2 is heard in all auscultatory areas while normal P2 is heard only in the pulmonary area. If it is heard at the apex, it can be considered as loud P2.
A high-frequency, accentuated P2 is apparent on the phonocardiogram (H_1, −32 dB) and is also audible on the sound clip. On auscultation with a stethoscope, an accentuated P2 was broadly audible from the precordium to the apex and was more easily identified during inspiration. In contrast, in healthy adults, P2 is usually not heard at the apex.

1st heart sound (S1) Clicks. S1 and the 2nd heart sound (S2, a diastolic heart sound) are normal components of the cardiac cycle, the familiar "lub-dub" sounds. S1 occurs just after the beginning of systole and is predominantly due to mitral closure but may also include tricuspid closure components. It is often split and has a high pitch.
The Second Heart Sound. The second heart sound (S2) indicates closure of the aortic (A2) and pulmonary (P2) valves. The second heart sound normally splits on inspiration and is single during expiration, and A2 (closure of the aortic valve) is louder than P2 (closure of the pulmonary valve), even in the pulmonary area.
