Noisebarriers generally prevent sound from passing through floors, walls, ceilings and other structures. It is because sound travels in waves, and these waves can bounce off hard, smooth objects like a rubber ball bounces off the ground.
What is noise barriers made of?   
Noise barriers are generally made of vinyl, a dense rubber material that also provides durability, strength and res     istance to moisture and humidity. Some of the sound barriers are made of MLV rather. MLV contains sand, salt or tiny metal particles for extra mass that propels sound blocking.
Can you combine noise barriers and other materials?
MLV and vinyl can be laminated to foams that absorb sound vibrations. Melamine, acoustical foam, is frequently used due to its flame-resistant, flexible, and lightweight.
How is noise blockers manufactured?
Noise blocking materials are supplied as rolls or sheets in different widths, lengths, and ...
... density. Water jet cutting is utilized to convert these stock materials to size and without tooling. If the noise barrier is used with a sound dampener or sound absorber, all these materials are laminated and then cut.
What exactly does these laminated products look like?
Noise blockers that are laminated to foams come with a sandwich style structure. When you hold the finished product from the side, you can notice the individual layers. Depending on the application, different kinds of acoustic materials might be used.
How are noise barriers applied or mounted?  
Noise barriers can be supplied with pressure-sensitive adhesive tape with a removable backing or liner. This PSA tape supports peel and stick installation for either permanent or temporary fastening. Generally, sound blockers are applied to the surfaces of vehicles, ceilings, walls or equipment.
Places where sound barriers are used in buildings
Sound blockers for buildings are installed between walls or underneath carpeting or flooring. Frequently, the barrier material is sandwiched between a layer of acoustic foam and a decoupler. Decoupling makes the acoustic foam and sound blocker to vibrate without each other. These are the things you have to keep in mind.
Are there any specific noise control standards?
Noise barriers have a STC that measures how much sound is blocked from passing through. Sound reduction is measured in decibels and used to calculate the efficiency of the products. They are also regulatory needs about maximum decibels in the workplace.  
What about flame resistance?
Tamer products are an instance of an FST standard.   
What are the different kinds of applications for noise barriers?
Along with railcars, buses and buildings, noise barriers are used in military land systems. When acoustic insulation is used as flooring in a vehicle like a personal transport, a non-slip surface and wear resistance might be necessary.  
Who provides custom noise barriers?     
O’Neill Engineered Systems provides noise barriers in USA. We can find noise blocking materials with a flame-laminated facing, and we can also laminate and water jet cut sandwich style structures.
