Movies are a good place for contemporary people to entertain and date. In an excellent film, in addition to good visual effects, good auditory effects are also important. Generally speaking, two conditions are required for hearing: one is to have good audio equipment; the other is to have a good acoustic environment, both of which are indispensable. In a good acoustic environment, even if the audio equipment is not very high-end, a good hearing effect can be obtained. Conversely, without a good acoustic environment, even if the audio equipment is high-end, the hearing effect will be greatly reduced. Just like the relationship between cars and highways: no matter how good a car is, it is just as unpleasant to drive when it encounters a bumpy road.
The sound construction plan of the cinema generally has two aspects:
First, the acoustic design of the cinema wall
Make wooden keel or light steel keel on the original wall, then fill the sound insulation cotton behind the keel, and then install the sound insulation board. This can not only achieve wall sound insulation, but also ensure that the sound quality of the cinema is not affected by the outside world. Finally, install the fabric sound-absorbing soft bag or polyester fiber sound-absorbing board (choose one of the two) professionally produced by Guangzhou Lisheng Company on the surface of the sound insulation board. This is both beautiful and sound insulation and sound absorption, and finally achieves the perfect acoustic effect.
Second, the acoustic design of the cinema ceiling
In addition to the need for sound construction on the walls of the cinema, the ceiling is also very important. The ceiling can be suspended with perforated sound-absorbing panels: use wood keel or light steel keel on the original ceiling, then fill the back of the keel with sound insulation cotton, and finally install the fire-proof perforated sound-absorbing board professionally produced by Guangzhou Lisheng Company.
