dB Acoustics Pty Ltd design and manufacture metal acoustic barriers for road and rail systems, screening of roof top air-conditioning equipment and industrial plants.

The barriers are very effective in minimising traffic noise. In many instances this enables freeways to be built through the center of densely populated urban centres, in situations where road and the dwellings may be only metres apart.

Metal barriers are preferable to traditional concrete barriers in a number of ways:

• Being lighter than other forms they avoid costly footings and settlement.
• Heavy and costly foundations not required cranes to install or replace if damaged.  Installation is fast and less expensive.
• With a wide range of anti-graffiti and durable paint finishes and patterns they are more aesthetically pleasing and maintenance free.

dB Acoustics produce noise barriers for the reduction in noise from:

• Road transport
• Rail transport
• Airports

Barriers are built up with dB Modulock panels constructed with galvanised steel with high-grade powdercoat finishes and anti-graffiti treatment. Barriers are either absorptive or reflective and available in a range of weather resistant materials including galvanised or stainless steel and aluminium.

Users of these barriers include NSW Roads Authority, the Victorian Roads Authority, Transfield Corporation (builders of Melbourne’s Citylink project), Thiess Contractors, Baulderstone Hornibrook, John Holland and Leighton Contractors.

• Being lighter than other forms they avoid costly footings and settlement.
