B
S1 is loudest, and therefore best heard, in the mitral area. S1 is heard the loudest in the mitral area and is caused by the closure of the mitral and tricuspid valves. S1 corresponds to the "lub" sound in the phonetic "lub-dub" representation of heart sounds. S1 is louder than S2 at this landmark. S1 in the tricuspid area is softer than S1 auscultated in the mitral area because the pressure in the left side of the heart is greater than that in the right. S1 is louder than S2 at this landmark. The midprecordial area is where both aortic and pulmonic murmurs can be auscultated. S2 is louder than S1 at the aortic area.
