Both the remodeling of facade and the ingenious combination of acoustics and aesthetics of internal auditorium have won good social repercussions. The two-way curved heavy ceiling is adopted for the top of auditorium, which can not only diffuse the sound, but also hide the lighting gallery. The side wall combines the sound absorber and sound reflection body to form a highly rhythmical wall, which creates good acoustic effect while bringing pleasant visual enjoyment to people.
