The decoration of a multifunctional hall requires consideration of many factors, including acoustic standards. In addition to perforated sound-absorbing boards and polyester fiber sound-absorbing boards, there are also other materials to choose from.

We can also choose from soft package sound-absorbing boards, slot wood sound-absorbing boards, aluminum sound-absorbing boards, glass magnesium sound-absorbing boards, etc. for wall sound-absorbing materials.

Ceiling sound-absorbing materials can be selected: space sound-absorbing body, fiberglass ceiling sound-absorbing board, etc., all suitable for places with high safety, fire prevention, and environmental requirements such as multi-functional halls.

The acoustic design of a multifunctional hall needs to consider many factors, including reverberation time control and indoor sound field control. The allowable noise level of a multifunctional hall should be determined based on the main function of the hall and the level of the building. Generally, NC-15 or NR-20 can be used, but at most, it should not exceed NR-25. The lower limit is for high-level multifunctional halls, while the upper limit is for less important halls.

The NC value is a noise standard used to evaluate indoor noise levels. NC-15 and NR-20 both refer to standards for indoor noise levels. For example, NC-20-30 represents very quiet and is suitable for important meeting rooms or large meeting rooms.

The above are some decoration suggestions and standards for the multi-functional hall. If they cannot fully assist you, you can send us a private message or leave a message for Chuangya Acoustics.
