About Betta Acoustic Barriers
The Betta Reflective Acoustic Barrier has evolved from the Berkshire Reflective Noise Barrier, the latter was one of the first to be designed for and approved by, the Department of Transport in the 1970's.
The Company has continued to improve the product and through demand developed the Betta Absorptive Acoustic Barrier. The Reflective and Absorptive Barriers both use the principal of steel universal beams with stress graded timber rails fixed through the web of the posts. This gives an easy flexibility for designing and building to any height, slope, step or differing top and bottom datum levels. The construction also allows different materials to be used on either face of the absorptive barrier. Security topping or earth retaining features may be included in the barrier design.
The Barriers are based on the Department of Transport Memorandum H14/76 including Amendment No. 1 and the more recent Highway Agencies HA 65/94 part 1 'Design Guide for Environmental Barriers' and HA 66/95 Part 2 Volume 10 'Environment Design'. The timber and steel components comply with the Specification for Highway Works (MCHW1) clauses 304, 310 and 311, these systems offer a 15 and 30 year life expectancy.
As with all Acoustic / Noise Environmental Barriers, they work on the principal of providing as large as an acoustic shadow as possible and therefore for maximum noise reduction barriers should be as long, as high and as close to the noise source or receiver as possible.
The Betta Absorptive Barrier is particularly important in applications where noise bounces back from reflective surfaces, so increasing the noise nuisance to neighbours.
What do we do?
The Betta Group offer a design, supply and installation service for the Betta Absorptive and Reflective Acoustic Barriers throughout the UK mainland.
In conjunction with our Consulting Engineer, we have the ability to design and manufacture to suit any height and ground conditions, including tapering to suit differing heights or ground levels. The Company also has the expertise to interpret and design to Sound Consultants specifications or complying with planning request on noise reduction or environmental impact.
