The method of purchase of acoustic board

An acoustic board is very common in our life, do you know how to distinguish a good acoustic board from a bad one? How does the acoustic board change to choose and buy? Today takes you to understand how to buy an acoustic board.

See if the installation of the acoustic board is simple

To achieve a very good sound insulation effect, the installation method of the acoustic board must be very simple, otherwise, it is difficult to achieve an ideal sound insulation effect. Professional acoustic engineers know that a wall with X decibels of sound insulation tested in the lab is often X-2 decibels of sound insulation, or even less. There are two main reasons for the wall sound insulation value in the actual project to be lower than the value measured in the laboratory: 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 that of the professionals in the laboratory. Therefore, the installation of the acoustic board must be simple, otherwise, the installation personnel on-site will make mistakes, resulting in the wall insulation value will not reach the sound insulation target. Elastic bar, for example, used in the United States is more, it 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.

Look at the thickness and weight of the acoustic board

There are some common acoustic boards on the market, to improve the sound insulation effect, it is to increase the thickness and weight of wall panels to achieve, this method can improve the sound insulation effect to a certain extent, but it brings a lot of shortcomings: sound insulation efficiency (that is, the improvement of sound insulation volume) is low because according to the laws of physics, the plate surface density increases twice, the isolation volume can only increase 6 decibels in theory; Four times the density of the wall panels increases the volume at most by 12 decibels. The thicker the wall panels, the more space they take up, and the more valuable living space people lose. The heavier the wall panel, the more difficult it is to install; And the wall panel is too heavy, but also need to consider the floor can bear the problem. The thicker and heavier the wallboard is, the more raw materials are used to produce the wallboard, the higher the price of the wallboard is, the higher the installation cost is, and the higher the value of the lost living space is, leading to the higher the comprehensive cost of the final project. The acoustic board is a kind of based on the completely new principle of sound insulation material, its sound insulation effect is not significantly improved by increasing the weight and thickness, in fact, only 18 mm acoustic board thickness, can even thinner, but made up of the light steel keel wall sound insulation effect can reach 53 decibels, adopt appropriate wall combination plan, the sound insulation of the walls can even reach 80 decibels. This kind of acoustic board is in the acoustic board product of the same thickness and weight on the market at present, not only sound insulation effect is best, but the sound-absorbing effect of the acoustic board that compares any same thickness and weight is better than a lot of times.

See how long the sound insulation lasts

A few acoustic boards on the market are to install rubber layer between two boards, reduce vibration material or sound insulation felt to wait for making it, use this kind of method, can raise sound insulation effect on a certain level in short term, but its sound insulation effect can be reduced gradually as time. As we all know, rubber and other materials will slowly be aging in the air, resulting in its gradual hardening and loss of elasticity, resulting in the sound insulation effect gradually reduced over time. On the other hand, the construction cost of installing rubber or soundproof felt between the two panels is also very high. The acoustic board is in the middle of two boards through special technology compound a layer of molecular new material, the performance of the material is unchanged for life, sound insulation effect at least maintain 50 years of more than not reduced. The acoustic sealant used to seal gaps in walls also remains viscoelastic throughout life, never cracking or deforming, and never reduces sound insulation.
