For the copy of the researchers stood the violin named? Betts Stradivarius? Model. Modern computed tomography made it possible to analyze the historical instrument of 1704 without disassembling it or even destroying it. With great caution, the researchers created more than a thousand individual cross-sectional images of the violin. Violins are not just simple wooden sound bodies? As with humans, they also have a wide range of individual variations, "explains Sirr. An instrument that is more than 300 years old makes tiny cracks, wormholes, repair traces as well as changes due to environmental influences a particularly unique object.
The CT images, which reflect these details, turned the scientists on the computer into a kind of three-dimensional blueprint. On the basis of this specification, a computer-controlled machine then milled exact replicas of the individual parts of the violin from different woods. Violin makers then put them together, varnished the finished instrument and gave it the final touch, based on the details of the CT images. display
Special fine structures of legendary violins have long been regarded as a possible source of their quality. There are theories that say that the wood the master used in the construction was unusually dense. Others suspect that the sound was created by mysterious wood preservatives with which Stradivari wanted to protect his instruments against woodworms. Whatever the cause, the end product is a violin that makes emotions resonate in many people. Researchers have also been concerned with this effect. The vibrational patterns of the Stradivarii violins are similar to the human voice, showing sound analysis. Your resonant body thus amplifies vocal-like frequencies that particularly flatter our ears.Steven Sirr (Mora, Minnesota) et al.: Contribution to the Annual Meeting of the Radiological Society of North America, Chicago © science.de?
