Design Inspiration

Project Name: Zhangjiakou Overseas Theater
Project Overview: The theater is located at the Yuanxiang Campus of Haidian Foreign Language Experimental School in Beijing, and is the 3rd Overseas Theater. The building area of the auditorium is 686.54 square meters, the total volume of the theater is 6881.9 cubic meters, and the total seating capacity is 796. Yushi Technology provided professional acoustic design solutions for the theater.
Detailed explanation of the plan: The main functions of the overseas theater of the theater are the activity center, lecture hall, multi-functional hall, etc., and it also needs to meet the needs of song and dance performances, drama, and speeches. The main function of the theater is language, requiring high language clarity and sufficient loudness, uniform sound field, fullness and familiarity, and no sound defects such as echo.
In the acoustic design scheme, a dedicated GRG acoustic ceiling is used for the ceiling, and the lifting angle is installed according to the computer sound line diagram, forming an arc-shaped shape to uniformly reflect sound energy to the audience hall. Wooden sound-absorbing panels are used on the side walls to effectively control reverberation time, while a strong sound-absorbing composite sound-absorbing soft package is used on the back wall to reduce sound feedback and eliminate microphone whistling. After the completion of the theater, the sound quality effect is 500Hz. The reverberation time in the empty space is RT60=1.21s, 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.
