When the stage sound insulation cover is used, it can meet the requirements of symphony concerts, chamber music and orchestral natural sound performances. The reverberation time of the auditorium at 500Hz is1.3 0.1s. The reverberation time of the concert hall with sound insulation cover is about 1.7s, which meets the requirements of the concert. The drama performance adopts natural sound and partial effect sound, and the acoustic design is mainly based on natural sound performance, supplemented by electroacoustic system.
The walls of the auditorium and stage area with the highest sound insulation requirements in the theater are reinforced concrete walls and double-layer infilled walls. The auditorium and stage entrance and exit in and out of the theater are isolated by glottis, and two fire-proof sound-proof doors are set. The wall surface of the stage area adopts strong sound absorption structure, and the interior wall and ceiling decoration of the sound control room adopt strong sound absorption structure. The air-conditioned room near the stage area adopts floating floor, with special elastic isolation layer formed by special rubber vibration isolation gasket, and the partition wall adopts double partition wall. The level of background noise control and sound control of the whole concert hall has reached a very high level, which can be seen from the numerous praises of the performing groups and audiences who came to perform after the completion.
