In the main room of this concert hall, previously there were acoustical problems in certain performances. The sound production was strongly reflected by some solid parts in the room, resulting in a bad sound experience in some places and even perceived as disturbing. To solve this problem, Texacoustic® 955.001/N00 has been used to make covers, which can be placed over the strongly reflective parts of the room. The high absorption capacity of the covers, has pleasantly improved the sound experience in the entire room.
