Scientific work published in the pages of a specialized journal Scientific Reports, reports Rus.Media.
Relaxation of the metacarpophalangeal joint, located at the base of each finger, produces a characteristic sound. At this point there is an expansion joint and the fluid that fills it, and appear active bubbles. Experts analysed this situation and found out that one joint is physically unable to crunch several times within twenty minutes.
The research used mathematical modeling for accurate treatment of the information received. The final model demonstrates the motion of air bubbles in the fluid when there is relaxation. Thus defined, the characteristic sound that accompanies the various stages of the process. Loudness and frequency the sound provocava explosion of bubbles, is almost identical with the crunch of the joint itself.
