Because this year, many friends asked whether the installation of sound barrier is effective, so share.
As mentioned above, the effect of sound barrier is more about the noise reduction ability of sound barrier, which means that the noise can be reduced from how much to how much. The following is a simple explanation:
(1) the factory installed sound barrier effect, in this shows that there are two aspects: one is that inside the factory, if the installation is sound-absorbing factory internal effective noise reduction can reach 30 decibel noise barrier around this particular case needs to see a noise decibel level, there is distance, but the sound isolation barrier among the internal office area and production area, office area generally can be reduced to 40 db below the noise. The other is the outside of the factory, such as four-sided or single-sided sound insulation, behind the sound barrier test, noise volume is not more than 50 db.
(2) effect of highway sound barrier installation. Since highway sound barrier is generally installed at a distance of more than 50 meters from residents around the highway, it is tested at less than 40 db in the residents’ yard, and at about 50 db next to the sound barrier, while 160 db noise is directly tested in the highway after leaving the sound barrier. What is the noise reduction effect of clickable highway noise barrier? Check out the live video.
(3) after the installation of the railway sound barrier, the noise can generally be controlled below 50 db and below 40 db in the residential area. Effectively comply with the state standards. The specific live video can be shown by clicking on the effect display of high-speed railway sound barrier.
Conclusion: the above is the specific effect after installing the sound barrier. Thank you for your reading. If you need more information, please consult our online customer service.
