GRG wall, with concave convex treatment of different scales, can play the role of acoustic diffusion and balance the pressure between the rear sound field and the front sound field. GRG wall often also affects the acoustic effect, because arc reflecting surfaces are made on both sides of the entrance, so that the near reflected sound focuses on the VIP seat, and some side walls are broken line treatment, so that the sound is reflected to the pool seat audience seat. Good acoustic effect, which is also the reason why GRG ceiling and GRG wall are becoming more and more popular.
The viewing platform breast board of the auditorium is a place where reflected sound or echo is often generated. In order to avoid sound quality problems such as echo and sound energy focusing, the viewing platform breast board of GRG material is usually treated by arc diffusion. Short time delay near reflection sound is very beneficial to improve sound quality.
The top of the theater building is the main sound reflecting surface. The curved ceiling separated from the wall of the auditorium is suspended above the auditorium. In order to broaden the effective diffusion frequency as much as possible, we often design GRG ceiling materials into blocks of different sizes. In this way, when hanging the GRG material ceiling, the acoustic reflector is composed of arcs with different widths and lengths, so as to ensure uniform sound field distribution. So as to achieve excellent acoustic effect.
