Acoustic barriers are a type of acoustic insulation that blocks undesired sounds rather than absorbing or muffling them. Being known as sound barriers or noise blockers, these products are made of thick rubber materials and are used at the sound source along its path.
Keep reading to know more about how sound barriers work, the way they are made, and the different kinds of products available.
In this contemporary society, getting peace and serenity is hard but still vital. An acoustic barrier can assist to block away undesired noise and makes places more peaceful.
There is a wide range of sound barriers to select from, so that you can get that works best for your project.
In this post, we will discuss about the different types of acoustic drapes and fencing available. 
What exactly are acoustic barriers?
Acoustic barriers, also called noise barriers or sound barriers, ...
... are privacy barriers designed to lessen sound transmission from one area to another.
Acoustic barriers work by reflecting, absorbing or diffusing sound waves, thereby lessening the noise effect or nearby residents or specific areas.
Different types of noise barriers available
Concrete noise barriers
 Also addressed as sound barriers, concrete noise barriers are generally made of precast or poured concrete, though other materials like metal or wood might also be used.
Acoustic panels
Acoustic panels are diverse and can be made from materials like fabric, fiberglass or foam. These panels absorb sound energy, lessening noise and echo.
They can be used in different applications, including concert stadiums and construction sites.
Timber acoustic fencing
Soundproof fencing or timber acoustic fencing is a special type of fencing designed to lessen noise pollution. Designed from top quality timber, these panels have specific design attributes to assist in deflecting or absorbing noise.
Not only do they ensure excellent security, privacy and work as an acoustic barrier, they are also quite aesthetically impressive, with a natural timber wood outlook.   
These barriers are designed           to reflect, absorb or diffuse sound waves, thereby lessening the noise that reaches the nearby areas. They are generally constructed alongside transportation corridors.     
Where is noise barriers used in buildings?
Sound barriers may come with a PSA tape with a removable liner or backing. The PSA tape supports installation for either permanent or temporary fastening.
Is there any kind of noise control standards?
Noise barriers have a STC that measures the amount of sound that is blocked from getting through. Noise reduction is measured in decibels (dB) and used to calculate the efficiencies of products. There are also regulatory needs regarding maximum decibels in the workplace.  
Some of the places where you can use noise barriers
Along with railcars, buses and buildings, sound barriers are used in military land systems. When acoustic insulation is used as flooring in a car, a wear resistance and non-slip surface might be necessary.
