Noise Absorption Office Acoustic Soundproof Panels is an ideal sound-absorbing decorative material. It has the advantages of sound absorption, environmental protection, flame retardant, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, parquet, simple construction, good stability, good impact resistance, good independence, and high cost performance. It is rich A variety of colors are available to meet the needs of different styles and levels of sound-absorbing decoration.
As people's requirements for a quiet environment are getting higher and Noise Absorption Office Acoustic Soundproof Panels are also used more in the decoration industry. So what principle does the Noise Absorption Office Acoustic Soundproof Panels use to absorb sound?
The first thing to talk about is the sound-absorbing material. The material of the sound-absorbing board is divided into two types: microporous type and fiber type. There is no difference in essence between these two materials. The principle of sound absorption is to leave sound in the material itself. Channels, these channels are made up of countless tiny holes that are connected together, and some channels are made up of countless fibers that are crossed and mixed to form gaps. It is precisely because these gaps are too long and chaotic that once the sound enters it is like a maze, once the sound enters, it cannot come out, but once the sound enters, it cannot come out. Because the passage is too messy and too long, the sound burrows through. Clashing left and right, gradually consuming energy in the process, playing a sound-absorbing role.
In order to achieve a good sound insulation effect, the installation method of the sound-absorbing panel must be very simple, otherwise it will be difficult to achieve the ideal sound insulation effect. Professional acoustic engineers know that if a kind of wall can be soundproofed by X decibels in the laboratory, it can only be soundproofed by X-2 decibels in actual engineering, and the sound insulation effect is even lower. There are two main reasons why the sound insulation value of the wall in the actual project is lower than the laboratory test value: including the lateral sound transmission problem in the actual project, and the installation quality of the wall panel in the actual project is not as good as the installation quality of the professional in the laboratory. of. Therefore, the installation of sound-absorbing panels must be simple, otherwise the on-site installers will definitely make mistakes, resulting in the sound insulation value of the wall not reaching the sound insulation target. For example, elastic horizontal strips have been used frequently in the United States. It is a good sound insulation method and product. Using elastic horizontal strips in the laboratory can increase the sound insulation effect of lightweight gypsum board walls by 5-10 decibels. However, in actual projects, installation workers often cannot accurately install the panels on the elastic crossbars, resulting in a very limited improvement in the actual sound insulation effect of the wall.
