Acoustic Design Project of Yunding Poly Cinema in Hengyang, Hunan

1. Project Overview

Project address: Hengyang, Hunan

Project scale: 1000㎡

Material used: TianGe Fabric Acoustic Panel

2. Analysis of acoustic design:

The average sound pressure level in the auditorium of the cinema can reach 80 ~ 85dB, sometimes it can be even higher. The noise standard in the hall is usually lower than concert halls, theaters and conference halls’. For ordinary theaters, the noise level is 40dBA, and the noise evaluation curve is NR-35; for multi-channel stereo theaters, it is 35dBA, and the noise evaluation curve is NR-30.

In principle, the reverberation time of the auditorium of the movie theater, regardless of the type of theater, should adopt strong sound absorption short reverberation and straight reverberation frequency characteristics, in order to make the film recording true. However, taking it into account that the different requirements for reverberation of mono-channel ordinary theaters and multi-channel stereo theaters, as well as the difference in the volume of the auditorium. Therefore, the reverberation time should have different standards with the volume. Considering the practical difficulties of controlling the low frequency reverberation time, it is usually allowed to have a certain improvement (relative to the intermediate frequency 500 ~ 1000Hz); while the high frequency reverberation time, due to the sound absorption in the air, and the audience and sound absorbing materials on the high frequency The actual situation is too strong and low.

3. Material advantages

TianGe fabric acoustic panel for cinema is made of Owens Corning fiber. It has the characteristics of environmental protection, fire-retardant, wide sound absorption frequency, good decoration, simple construction, no dust pollution, etc., and rich color chart for finish materials to choose, which will well meet the customers’ diverse acoustic and decorative needs.
