In conclusion, the dub sound in the heart is a critical component of the cardiac cycle, caused by the sudden closure of the aortic and pulmonary valves. The dicrotic notch plays a key role in generating this sound, which serves as an important indicator of cardiovascular health. what makes the dub sound in the heart
