Sound for all!
The solution that Toyota and his team devised, together with the architects from Herzog & De Meuron, is based on the so-called vineyard principle, in which the audience ranks are grouped around the orchestra in the middle of the hall. No visitor sits more than 30 m away from the conductor in the Great Hall. Technology, calculations and millimetre work are the vocabulary that the physicists, engineers and electrical engineers in Toyota's team must master perfectly. With the goal of the democracy of sound in mind, the idea of the so-called "white skin" for the wall and ceiling cladding in the concert hall was born: 10,000 individually milled, flaky gypsum fibreboards, each of which weighs around 70 kilos (their production alone took one year because the corresponding machines had to be built first). The purpose of the panels: to form reflectors that break and reflect the tones played by the orchestra in the concert hall, thus providing ideal acoustics. In most concert halls, a maximum of five percent of the sound reaching the ear comes directly from the stage - the rest has been reflected at least once somewhere in the hall.
