Which part of the heart makes the heartbeat sound?
A heartbeat produces the familiar "LUB-DUP" sounds as the chambers contract and the valves close. The first heart sound, "lub," is heard when the ventricles contract and the atrioventricular valves close. This sound last longest and has a lower pitch. The second heart sound, "dub," is heard when the relaxation of the ventricles allows the semilunar valves to close.
How many decibels does the human heart make?
Does a heart make decibels? Never heard a heart.
What causes the lubb dupp heart sounds that are heard while taking a apical pulse?
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).
What are the heart chambers that are filled when you hear the first heart sound?
after the first heart sound is made ventricles starts emptying.
Would turbulence of blood flow through the aortic valve give rise to the first heart sound?
No. The heart sounds are caused by the closure of heart valves. The first heart sound is caused by the closure of the AV valves (tricuspid and mitral). The second heart sound is the result of the closure of the aortic and pulmonic valve after the completion of systole. Turbulence of blood flow through the aortic valve would cause a murmur (an abnormal heart sound) during systole.
Where is the s1 heart sound heard the loudest?
S1 makes a "lub" sound. It is the first heart sound in a normal rhythm. The sound is produced when the AV valves close.

How many decibels does the human heart make?
Does a heart make decibels? Never heard a heart.
What causes the sounds that are normally heard when listening to the heart through a stethoscope?
The sound is caused by the closing of valves in the heart.
What causes the lubb dupp heart sounds that are heard while taking a apical pulse?
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).
What cause the lubb-dupp heart sounds that are heard while talking an apical pulse?
The closing of the valves in the heart. The first sound is caused by the closing of the atrioventricular valves within the heart. The second sound is caused by the shutting of the aortic and pulmonary valves.
What is an abnormal sound heard when listening to the heart or neighboring large blood vessels?
heart murmur
What heart sound is stronger at the apex of the heart?
First heart sound S1-LUB
Who first heard of sound?
the first one to hear a sound is obviously the first man on the earth!
What are the heart chambers that are filled when you hear the first heart sound?
after the first heart sound is made ventricles starts emptying.
What do you call a gurgling or swishing sound heard upon auscultation of the heart?
Murmur
What valve sound heard at base of the heart?
The mitral, or bicuspid valve
