Project Name: "Dream Back to Ba Country" in Bashan Grand Canyon
Project Overview: The theater is located in the "Dreaming Back to Ba Country" scenario theater in Bashan Grand Canyon, Xuanhan County, Dazhou City, Sichuan Province. The building area of the auditorium is 927 square meters, the total volume of the theater is 15239 cubic meters, and the total seating capacity is 736. Yushi Technology provided a comprehensive acoustic decoration solution for the theater, including deepening of acoustic design schemes, production and construction of acoustic materials.
Detailed explanation of the plan: The main function of the "Dream Back to Ba Country" theater is to perform situational song and dance dramas, requiring high language clarity and sufficient loudness, uniform sound field, fullness and familiarity, and no sound defects such as echoes. Therefore, we adopt sound absorption and diffusion treatment measures to reduce indoor reverberation time and ensure indoor sound quality.
In the acoustic design scheme, a reinforced fiberglass sound-absorbing ceiling is used for the ceiling, and the lifting angle is installed according to the computer sound ray diagram, forming an arc-shaped shape to uniformly reflect sound energy to the audience hall. The upper part of the side wall is installed with 25mm AGG aggregate sand sound-absorbing board flat pasted on the curved base board. This is a seamless sound-absorbing material with a wide sound-absorbing frequency band, which can meet any shape. Effectively control indoor reverberation time and eliminate sound defects. The lower part uses 20% perforated aluminum plate to achieve the requirement of a "suspended" sensory audience seat and meet the acoustic effect. The sound quality effect of the theater design is 500Hz. The reverberation time in the empty space is RT60=1.50 ± 0.1s, and the noise meets NR-35; Under natural sound source conditions, the unevenness of the sound field in the hall is ≤+4dB, and the maximum and minimum sound level difference is ≤ 8dB.
