Liquan Grand Theater, Xianyang City, Shanxi Province
Liquan Grand Theater in Xianyang, Shanxi province has applied a Soundbox fixing the acoustic system. During acoustic design, our principle was to place architectural acoustic treatment first, electronic system second. Based on such design, Soundbox technicians controlled not only the RT60 by frequency sound absorption, but also helped this theatre achieve curtain first reflection.
A grand theatre is supposed to have suitable sound diffusion to gain an even acoustic field without echo, sound focus, resonance, or sound fluttering. It is better if it is not disturbed by noise with suitable RT60, because of suitable sound diffusion, vivid first and side reflection, no sound defects, and low background noise.
Through our upgrade, the Liquan grand theatre finally matched the original design, working at a better national standard. After upgrading, sound in this theatre is clear and full for movie projection and video meetings.
