Important things to take into consideration when designing or building walls of noise, "noise barriers," there are 2:1) Insertion Loss of Barriers Is designed to act as noise walls object that allows the volume of the sound wave frequency and the district from the origin of the sound and to coordinate each other (because it occurred in the same area where a sound wave can be both compatible) The level of sound reduction or a summary description of "making waves audio turn turn around from the source to the destination, or the recipients themselves."2) Transmission Loss of BarriersIs designed to reflect sound, noise walls are removed along with part of the sound absorption values taken part? Before allowing a sound wave traveling through a hole to the other side. Which, according to the General rules of the wall material of the selected audio. Must reduce the sound has no less than 6-10 dBA, or if the material is appropriate to the problem in the source, and the seal very well. There is no sound through channels. The walls of noise, it may reduce the sound up to 20 dBA.
