Scientists managed to reproduce the sound of the Tsar Bell
Listen to these "royal" sounds now anyone can
As is known, the largest of all known bells - the Tsar Bell, never sounded in reality. For hundreds of years the bell and its breakaway part have been put on display. Naturally, everyone who saw the Tsar Bell or read about it, I would like to know how this giant should have sounded in reality.

Modern experts have already decided to model the bell itself and its sound using computer systems. Representatives of the University of Berkeley led by Greg Niemeyer did this. In order to tell about their work, the scientists also created a website where there is a large amount of information about the bell and its sound modeling technology.
Initially, scientists set out to find out how the “tongue” of a bell would deform the walls of the system if the Tsar Bell were whole. For this, it was decided to use the finite element method . The finite element method (FEM) is a numerical method for solving partial differential equations, as well as integral equations arising in solving problems of applied physics. The method is widely used for solving problems of deformable solid body mechanics, heat transfer, hydrodynamics, and electrodynamics.
Understanding how the bell walls were subjected to deformations, the project participants were able to calculate the acoustic waves generated by these deformations. It is clear that the technique required verification, so it was decided to simulate the sound of existing bells, and compare the model with reality. This was done:
On Friday, the first demonstration of the sound of the Tsar Bell was held. Audio files can be found on the project website .
The giant bell was cast in 1735 by decree of Empress Anna Ioannovna. In 1730, the empress ordered to pour the broken Grigoriev bell with the addition of metal and bring the weight of the bell to 10 thousand pounds (the actual weight is about 200 tons). The bell was cast by Russian craftsmen Ivan Motorin and his son Mikhail Motorin in 1733-1735 at the Cannon Yard.
