The curve of the ceiling follows the seating profile as closely as possible to get the best sound. Additionally, the wood ceiling slats are heavy enough to bounce back low-frequency waves. A noise-absorbing mineral fiber layer is above the wood. Ten acoustic reflectors over the stage area direct sound back down to the orchestra seats. There are 35 additional reflectors distributed over the rest of ceiling, with vibration dampers on top of each.
Every reflector is a different size, to maximize the sound dispersion.
