Design Criteria and Basis:
1. National Standard of the People’s Republic of China GB3096-2008 Sound Environment Quality Standard ;
2. The National Standard of the People’s Republic of China GB22337-2008 Social Living Environment Noise Emission Standard ;
3. National Building Standard Design Atlas 08J931 Building Sound Insulation And Sound Absorption Structure ;
4. National Standard GB /T 50356-2005 Code For Architectural Acoustics Design of Theaters, Cinemas and Multi-Purpose Halls ;
5. Effective feedback from Party A and various professional designers.

Acoustic Design Idea:
According to the acoustical design of the banquet hall, it is required that the sound should have enough loudness, clear hearing, no echo and no vibrating echo. In addition, due to the high requirements of the interior decoration of the banquet hall, the acoustic design should maintain the original designer’s luxurious and elegant decorative design concept as far as possible. The acoustic design should take the acoustic effect of the banquet hall into account in order to achieve a unified decorative effect and acoustic effect.

Note: The above is the minimum required reverberation time.

Acoustic Design:

1. According to the above requirements, it is necessary to install TG-75 mm thick decorative soft sound absorption panels, sound-absorbing glass cotton should be less than 1,228 m³, slotted acoustic material with 90 mm thickness should be less than 830 m².

2. Because the distance between the front wall and the back wall is as long as 67 meters and the free sound field is too long to form Echo easily. It is suggested that the back wall should be made of sound absorbing and diffusing material: 90 mm thick curved aluminium slotted acoustic panels 300 square feet.

3. Attach a 25 mm thick soft sound absorption panels with an aluminium frame to the partition panel.

4. In terms of sound insulation, the walls of the banquet hall must be plastered on both sides, and the thickness of the plastering surface should be more than 20 mm.

5. Considering the banquet hall roof is the Color Steel Plate metal roof, the rain will seriously interfere with the normal use of the function in the hall when the rain knocked on the metal roof. Therefore, the ceiling installed TR32 series sound insulation board, built-in 50 mm sound-absorbing cotton, Keel surface damping materials, to reduce indoor background noise.
