the sounds of the heart "LUBB-DUPP" are produced due to the sharp closure of the valves of the heart. the first sound is produced when the auricular-ventricular valve(bicuspid and tricuspid valve)closes. the second one is produced when the semilunar valves(pulmonary and aortic valves) close.

∙ 12y agoThe sound from heart is due to opening and closing of valves. There are 4 sounds that heart makes. They are called: S1, S2, S3 and S4. The latter two if heard, are not normal and the heart beat sounds like horse's gallop. Thus, last two are called gallop rhythms.
What we can hear mostly is First and second heart sounds as lub and dub. Lub is made by closing of atrioventricular valves. It is called by closure of semilunar valves.
It is important to know that, rather than valves making sounds like a clap, the sound originates from stopping of blood flow due to valve closure.

∙ 13y agobecause its pumping so much blood at a time.
its the sound of the valves opening and closing from your heart

∙ 13y agoThe sound of the heart comes from the left ventricle and right ventricle contracting very quickly. The blood then travels to the lungs and the rest of the body.

The sound of a heart beat is usually described as a thump.
Is there any difference between the heart pumping blood and the heart beating?
Yes the "heart beat" is just the sound of the valves opening and closing, not the sound of the blood being pumped.
How is a heart beat produced?
The heart beat, also called heart sounds, is produced by the closing of the valves. The valves produce two sounds, known as lub-dub. The atrioventricular valve closing produces the first sound, or lub, and the semilunar valve closing produces the second sound, or dub.
When your heart goes bump bump is that one or to heart beats?
It really is lubb dupp and it is the sound of the 4 valves closing, two at a time. This occurs during one heart beat.
When the blood passes to the right or left ventricle a valve will close between the atrium and ventricle what sound does it create?
The closure of the atrioventricular valves causes the first heart sound. We hear this as the "lub" of the "lub DUB" heart beat.
What does the beating sound of your heart come from?
The sound of a heart beat is caused by the closing of the valves in the heart.
What creates the sound of a heart beat?

What are you hearing when you hear the heart beat?
Turbulence. Be it normal or abnormal, the "sound of blood" is always turbulence. This includes what you hear when you take a blood pressure ... which is a major source of error IF blood flow is abnormal (as in shock).
What does a healthy heart sound?
In healthy adults, there are two normal heart sounds often described as a lub and a dub, that occur in sequence with each heart beat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the AV valves and semilunar valves respectively.
What is the dupp sound of a heart contraction?
A normal heart beat generally consists of 2 distinct heart sounds, informally termed 'lub' and 'dub'. The first heart sound (lub) occurs at the beginning of the heart contraction (systole) and is the sound of the valves between the atria and ventricles closing. The second heart sound (dub) occurs at the end of the contraction, and is the sound of the valves between the major arteries and the ventricles closing.
