Fabric Acoustic Panel|Sound-absorbing Treatment in Cinema

What is the Purpose of Sound-absorbing Processing in Cinema?

As people's entertainment needs increase, various large-scale cinemas continue to appear. In addition to eye-catching interior and exterior decoration, cinemas also need good acoustic decoration.

The cinema will play multiple movies at the same time. If the sound insulation of the cinema is not handled properly, interference will inevitably occur between the broadcasting halls. The sound insulation effect of the cinema will directly affect the enjoyment of the audience watching the movie.
 

Features of Fabric Acoustic Panels

(1)Use flame-retardant grade A high-quality glass fiber sound-absorbing cotton.

(2)The decorative surface includes fabric, leather, etc., and there are also many colors to choose from.

(3)wide sound-absorbing spectrum and the high sound-absorbing coefficient.

(4)Good sound absorption effect for low, medium, and high-frequency noise.

(5)It has the characteristics of environmental protection, a wide range of sound absorption, easy installation, no dust pollution, etc.

(6)With high-efficiency sound absorption and noise reduction performance, it is suitable for places with high acoustic performance requirements.

Precautions for Sound-absorbing Treatment in Cinema

(1) Some sound-absorbing materials have good mid-and high-frequency sound absorption performance, but low-frequency sound absorption performance is poor. If such materials are selected in a movie theater, the reverberation time of the middle and high frequencies will be short, while the reverberation time of the low frequency will be longer, and the speech intelligibility will be insufficient.

(2)The sound-absorbing of the cinema should not be too small. Among the 6 sides of the cinema, at least 5 sides need to be treated with strong sound-absorbing.

(3)For a cinema with a rectangular auditorium, it is recommended to tilt the sound-absorbing wall and ceiling at a certain angle to eliminate vibration and echo.

(4) For movie theaters with an arc or hemispherical auditorium, it is recommended to use full-frequency sound-absorbing materials as sound-absorbing diffusers to eliminate sound accumulation.

(5)When applying for metal perforated plates as sound-absorbing structure-facing materials, take measures to prevent the metal plates from resonating.

Conclusion

For the sound-absorbing treatment in the cinema, we must first make a good acoustic design plan, including the selection and determination of the best reverberation time and its frequency characteristics, the combination of sound-absorbing materials, and the design of appropriate reflecting surfaces. Then to choose the right acoustic material and use the right material to get twice the result with half the effort.
