The opening and closing of the heart valves.
Such questions will continue to come from senior doctors. When you listen some abnormal heart sounds, you should go for ecocardiogram of the patient. With Doppler study, you will get complete information of the defects and blood flow of the heart. You have to listen heart sounds very routinely to know the 'normal' heart sounds. There is no short cut for the same.
Heart sounds are created primarily from turbulence in blood flow created by the closures of the valves.
Audible patterns are the heart of music.
The heart is caused by severe heart problems that eventually can lead to inificant heart beats
Your heart beat of course.
Normal heart sounds are caused by the heart beating. This is the process of the heart muscle contracting and relaxing as blood flows through the various chambers.

Mummur's are pathologic heart sounds that are produced as a result of turbulent blood flow that is sufficient to produce audible noise. Most murmurs can only be heard with the assistance of a stethoscope.
lub and a dub (or dup)
The closure of mitral and tricuspid valves causes the first heart sound. The second heart sound is produced by the closure of semilunar valves (pulmonic and aortic valves).
That sounds like heart disease of some kind; it might be atrial fibrillation. In any event, consult your doctor.
