The Russian scientist Piotr Ufimtsev invented the original stealth fighter in the 1950's. The only problem was it did not fly.
In the late 70's American scientists made the technology work with computer help. The stealth fighter had been created and was invisible for radar waves.
In the 90's, Voxativ transferred this non-reflecting technology into the musical band to optimize housing resonances. Acoustic Stealth Technology was born.
