Sound Barriers (also known as Noise Walls, Noise Barriers, Noise Fences or Sound Barrier Walls) have been made of a number of different materials over the years. Noise barriers are solid obstructions built between noise sources, be it highway noise or air conditioning equipment,that are designed to be “line of sight” interruptions between the noise source and the receiver.

FAQ
1.What is a highway acoustic barrier and how does it reduce traffic noise?
A roadside structure placed between the traffic and the receiver that blocks the direct sound path, absorbs or reflects energy at its surface, and forces sound to travel a longer diffracted path over the top.
2.What insertion loss can be expected from a highway barrier?
Achievable insertion loss depends on barrier height, distance, terrain and source spectrum; performance is normally verified by calculation (for example ISO 9613-2) and stated as D_LR per EN 1793-2.
3.How is barrier height decided for a highway project?
Height is derived from the source-to-receiver geometry and the required reduction at the nearest sensitive receptor, then checked against structural and sight-distance constraints.
4.Should a highway barrier be absorptive?
Absorptive facings are usually preferred where barriers face each other or where a sensitive receptor sits opposite the barrier, because they limit the build-up of reflected noise.
