Core hints:Application of glass fiber sound absorbing ceiling: sound absorption and sound insulation.

Sound waves in the process of transmission, run into a homogeneous shield, because of the change in two interfacial resistance to reflect in that part of the sound waves are blocked, and part is absorbed by the shield, a division of the sound waves can only through the shield to another space. This phenomenon is known as sound insulation.
When the sound is transmitted by the sound wave, some sound waves can be reflected by the boundary surface, and some of the sound waves can be absorbed by the boundary surface or directly projected onto the other side of the boundary. In addition to the reflected sound waves reflected in the original space, the rest of the energy is seen as being absorbed by the boundary surface.
When people are choosing the glass fiber sound absorption ceiling, it is important to distinguish the difference between the two. The main function of the fiberglass ceiling is the sound absorption.
For a single material, the sound absorption capacity and sound insulation effect are often not considered. Such as brick wall or steel sheet can serve as a good sound insulation materials, but sound-absorbing effect is poor, on the contrary, sound-absorbing materials, with good effect on sound insulation effect is relatively poor, such as glass fiber sound-absorbing board, main function is sound-absorbing, it can absorb sound waves, but at the same time, it will be a part of the sound wave through it, and spread to another space. Therefore, it is not accurate for people to refer to the sound absorbing material as the sound insulation material, and people should distinguish clearly when buying.
There are many kinds of sound absorbing materials and sound insulation materials in the market, and they have their own characteristics in terms of performance and appearance. Such as glass fiber sound-absorbing ceiling, light weight, sound-absorbing the effect is good, beautiful modelling, color is rich, has sound-absorbing function not only, still have strong decorative effect, as a ceiling in the modern architectural decoration application, loved by the people.
