Nowadays, the use of sound-absorbing panels is more and more widely used. There are more and more sound-absorbing panel manufacturers, sound-absorbing panel brands, sound-absorbing panel types, sound-absorbing panel specifications, and sound-absorbing panel prices. Expected and desired results. So how can we choose sound-absorbing panels correctly? From what aspects should I judge whether it is what I need?
(1) Check whether the sound-absorbing panel has relevant test reports
According to scientific theory, any material has sound insulation properties, so there are many sound-absorbing panels made of messy materials on the market, including some gypsum boards, magnesium boards, calcium silicate boards, wood boards, etc. Many consumers do not understand this. So it is easy to be deceived. One of the most important factors in choosing sound-absorbing panels is to see whether the sound-absorbing panels have relevant test reports. At present, the most authoritative testing units in China are the Institute of Building Acoustics of Tsinghua University and Tongji University. At present, many businesses on the market boast about how good their products are, but they can’t actually produce any formal test reports. If a sound-absorbing panel advertises how good its sound insulation is, but can’t produce an authoritative report, this is the consumer. Be sure to choose carefully. Also need to pay attention to whether the sound-absorbing panel sold by the manufacturer and the sample submitted for inspection are the same product. If the received goods do not match what was seen at the time, then it is obvious that the physical object cannot reach the sound insulation value indicated in the test, so the manufacturer’s qualifications, credit, and goodwill are also very important.
(2) See if the sound-absorbing panel is easy and convenient to install
The simpler the installation method of the sound-absorbing panel, the better its sound insulation performance. Professional acoustic engineers know that if a 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. If the installation method is cumbersome, the installer will definitely make a mistake, resulting in the sound insulation value of the wall not reaching the sound insulation target.
(3) Look at the thickness and weight of the sound-absorbing panel
At present, many people in the market increase the thickness and weight of wall panels in order to improve the sound insulation effect. Although this method improves the sound insulation effect to a certain extent, it brings many disadvantages. For example: the thicker the wallboard, the more space it takes up; the heavier the wallboard, the more difficult it is to install; the thicker and heavier the wallboard, the more raw materials used to produce the wallboard, the higher the price of the wallboard and the installation cost The higher it is, and the loss of the spatial value of the living environment.
