Design Inspiration

Project Name: Acoustic Design of Shunyi Fuzhou Theater
Project Year: 2017
Project Address: Shunyi District, Beijing
Project purpose: The main functions of the theater are small-scale song and dance performances, plays, speeches, etc., and it also needs to meet the needs of holding conferences.
Project Introduction: The theater is located near Xin Guozhan in Shunyi District, Beijing. It was previously an industrial factory and is part of a renovation project. After renovation, it will be used for artistic performances. The total construction area of the project is 5859.82 square meters, with an audience hall construction area of 222 square meters and a total seating capacity of 313. It is classified as a small theater according to the number of audience seats. The total volume of the theater is 2818m ³, with a plot ratio of 5.4 m ³ per seat. The main functions of a small theater are small-scale song and dance performances, plays, speeches, etc., and it also needs to meet the needs of holding conferences. When performing plays and giving speeches, natural sounds are mainly used. Due to the fact that the theater needs to meet both the functions of artistic performances and the requirements of language halls, the mid frequency (500Hz-1000Hz) of the full reverberation time of the theater is determined to be RT=0.9 ± 0.1s, and the empty room RT=1.0 ± 0.1s; the background noise meets the requirements of the NR-30 noise evaluation curve.
Materials used in the project: The overall side walls of the building are made of Kaufman sand seamless sound transmission system, with an acoustic requirement of NRC ≥ 0.75. The ceiling is made of gypsum board material to create reflective panels. Through sound analysis, the entire layered shaped ceiling is assembled and installed. In order to control reverberation time and meet different functional requirements, wooden decorative panels are used for the side walls under the stage, which can be opened and closed by sliding. At the same time, adjustable sound-absorbing curtains are hung. The upper side walls still use Kaufman sand seamless sound transmission system to ensure that actors can obtain the same acoustic effect as the audience during stage performances.
