What are the minefields in selecting sound absorption materials for movie theaters?

It is inevitable that there will be some minefields in the selection of products, and the same is true in the selection of sound absorbing materials for movie theaters. Let's discuss what minefields there are in the selection of sound absorbing materials for movie theaters.
 
A brand is an important part of measuring the credibility of a product. In this respect, consumers should pay attention to identify the manufacturer's qualification, credit and goodwill when choosing sound absorbing materials for the cinema, so as to avoid being deceived as far as possible.
 
Next, the installation that should see sound-absorbing board when choosing cinema sound-absorbing material is simple. In order to achieve good sound insulation effect, the installation method of sound insulation board must be very critical, otherwise it is difficult to achieve the ideal sound insulation effect. It is well known to professional acoustic engineers that if a wall can be tested in the laboratory, it can only sound x-2 decibels in practice, or even lower. There are two main reasons why the sound insulation value of the wall in the actual project is lower than that of the laboratory test value: lateral sound transmission in the actual project, and the installation quality of the wall panel in the actual project is not as good as that of the professionals in the laboratory. Therefore, the theater sound absorption material installation must be simple, otherwise the site installation personnel will certainly make mistakes, resulting in the wall sound insulation value can not reach the sound insulation target.
 
Cinema sound-absorbing material installation must be simple, for example, elastic bar used in the United States is more, it itself is a kind of very good sound insulation methods and products, in the laboratory using elastic stripes lightweight gypsum board wall sound insulation effect can be increased 5-10 decibels, however in the practical engineering, installation workers often cannot install plank accurately on the elastic bar, wall actual sound insulation effect is very limited. Therefore, the installation of sound absorbing materials must be taken into consideration in the selection of sound absorbing materials.
