Why is the noise when the fingers are shaken?

_100641023__100610091_gettyimages-532125424.jpgThe attention of the scientists is on one of the most awkward habits of people – why do the voices on the fingers get shaken?

Researchers from the United States and France say that the reason for this can be explained with the help of three equations of mathematics. From their model it proves that these sounds occur due to the bubbles in which the fluid is formed in the joint of the bones.

Surprisingly, the process has been debated for a whole century.

Vineet Chandran, a science student in France, was trying to get his fingers in Suja Class when he thought of finding out about it.

He created a series of mathematical equations with his teacher Dr. Abdul Barkat, with the help of which to explain why and why the voices of fingers and wrists jumped.

Burst bubbles
They told the BBC, “The first equation revealed that when we pick our fingers, there are different pressures in our bones’ joints.”

“The second equation shows that the size of the bubbles is also different with different pressures.”

“In the third equation, we added different sized bubbles with the size of the bubbles that sound.”

Chandran Sooja said that from all these equations one has become a complete mathematical model which tells about the sound of the finger-twisting. Chandran is currently postgraduating at Stanford University in California.
When we take our fingers, we are pulling our joints together. And when we do this then the pressure is less. The bubbles are in the form of liquid which is called the sinoclique fluid. The pressure of the joints changes in the process of twisting the fingers and the bubbles also increase rapidly and the sounds start to rise.

Opposite principle
From this model, there seems to be a connection between two opposite theories. The sound of the bubble burst arises, this thing first came out in 1971.

But after 40 years it was challenged after new experiments in which the bubbles were told that the fingers remained in Fluid even after a long time.

After this new model, this issue seems to be resolved, because according to this, the burst of some bubbles creates a sound. Therefore, even after cutting fingers, small bubbles remain in the liquid.

This study has been published in the Scientific Reports Journals, which suggests that the pressure caused by the bubble burst creates the wave, which can be understood by mathematical equations and measured.

It also shows why some people do not click their fingers. If the fingers of your fingers have more space in the bones then the pressure is not enough to create the sound
