The definition of heart murmur sounds is "any extra or unusual sound made by the heart as it beats." When listening to normal heart sounds you will hear a "lub-dub" sound when the heart beats. There should be no other sounds associated with the heart beat. If there are that means that there is something going on that is out of the ordinary and should be investigated fully.
The normal "lub-dub" is heard when the heart's valves open and close while pumping blood to either the lungs or to the rest of the body. When the valves are damaged and blood leaks through the valve or backs up in the heart is when the heart murmur sounds are heard.
