The Great Hall of the People in Beijing is 336 meters in length from north to south, 206 meters in width from east to west and 46.5 meters in height. It covers an area of 150,000 square meters and has a construction area of 171,800 square meters. CCTV is our “voice of China” and our national television station. Whether it is the Great Hall of the People in Beijing or CCTV, both have relatively high requirements of the acoustic building design, so whether in the selection of acoustic design brands or acoustic materials will be relatively rigorous.

Foshan Tiange Science and Technology Co., Ltd. is a large-scale professional manufacturer of acoustic materials in China. Since it established 10 years ago, the company has focused on the R & D, production and sales of various sound absorption and sound insulation products. The company has been awarded as Guangdong High-tech Enterprise, receiving ISO 9001:2015 certification, European Union CE Certification, and is a large-scale manufacturer in the acoustic industry.

TianGe Acoustics is an acoustic brand with high visibility and good public praise in the Industry and has developed to date to be more mature and perfect in terms of both technical design and service. Therefore, we have the honor of doing the acoustic design and offering the services for the project of the Beijing Great Hall of the People and CCTV.

This project not only needs to meet the requirement of the acoustic environment of the building but also to meet the aesthetics of the interior decoration. Therefore, TianGe Acoustics has made a series of analysis and design according to the characteristics of the project:

The acoustical design features of the Great Hall and Other Conference Halls: The difference in size (both volume and capacity) of the Great Hall of the People in Beijing is greater than that of other conference halls. Some halls are as small as a room that can only accommodate a dozen people with the volume of about 100 square meters; some halls are as large as the Great Hall of the People can accommodate over 10,000 audiences with the volume of 100,000 square meters or even larger. The gap among them is relatively large. Therefore, the corresponding reverberation time is also very different, we need to determine the reverberation time value according to the volume, usually in the range of 0.5 s ~ 1.8 s

Secondly, in the choice of materials, TianGe Acoustic makes the use of these products — Aluminium Strip Acoustic Panels, Perforated Acoustic Panels And Large-Scale Soft Sound-Absorbing Packages.

TianGe Aluminum Strip Acoustic Board is an upgrade product originated from the wood acoustic board, aluminium perforated board, composite slotted board. Its fire performance is Class A non-flammable and has the characteristics of moisture-proof, insect-proof, anti-mildew, non-methanol, not easy to deformation, impact resistance, easy to scrub, simple installation, but also has full-frequency sound absorption.

The TianGe perforated acoustic panel has better sound-absorbing performance in middle and low frequency. The perforated acoustic panel uses high-quality panel, which has a strong anti-impact ability and also has environmental protection, fireproof, waterproof and other properties. Its fire protection performance can reach Grade A2 and its environmental protection performance can achieve Grade E1.

TianGe large-sized sound-absorbing soft package has the features of environment-friendly, fire protection, no dust pollution and its construction is simple, It also has a wide selection of decorative colors and materials, which can meet the acoustic and decorative needs of various customers. It not only meets the technical requirements of acoustic architecture and national environmental protection but also has the aesthetics of the venue.

The Great Hall of the People in Beijing and CCTV are big projects that receive a lot of attention, while TianGe Acoustics has overcome numerous difficulties and pressures, completed the acoustic architectural design and construction of the project with high-standard, high-quality, high-demand, high-efficiency. What we did not only contributes our own strength for the country and the project but also adds a brilliant achievement for the development of TianGe Acoustics!
