The ceiling is made of fiber gypsum molding board, a heavy material that can effectively prevent low-frequency absorption and enhance the hall's low-frequency reverberation time, so that the bass effects (such as organ, tubas, cellos, etc.) are more powerful and infectious.
In order to achieve the perfection of the sound effect, in the roof of the following also hangs a tortoise back shape of the centralized antiphonal plate, commonly known as the "tortoise back antiphonal plate", its role is to scatter the sound in all directions.
