Overview

275m of 3.5m-high Jakoustic Commercial and Highway acoustic barriers and double-leaf acoustic gates were installed to reduce noise at a new housing development being built close to a multi-purpose stadium.

Challenge

With the potential to hold a range of sporting events, it was imperative that noise mitigation measures were installed prior to the completion of the housing development to reduce as much noise as possible and create a peaceful living environment for residents.

Solution

Over 275m of 3.5m-high Jakoustic® Commercial and Highway reflective acoustic barriers were installed around the perimeter of the stadium. Due the stadium's shape, the installation followed a gradient. To provide strength and correct wind loading, acoustic barriers over 3m tall are installed with steel I-beams. These are galvanised as standard but, in this case, the customer wanted green powder coating to further increase aesthetic appeal.

A matching 4m-wide double-leaf acoustic gate was also installed for access.

Jacksons acoustic barriers are provided with a 25 year guarantee against rot, insect attack, rust and corrosion, providing a low lifetime cost.

Outcome

The installation of the acoustic barrier and gates will not only reduce noise, but also provide homebuyers with the reassurance of knowing that noise mitigation solutions are in place.

About acoustic barriers

Installing an acoustic barrier involves careful planning and research and, ideally, the use of experienced acoustic consultants. There are multiple factors to consider: height of the barrier; distance from noise source; type of acoustic barrier (reflective or absorptive), and there are strict principles to follow for a fence to be an effective acoustic barrier. Mass density, sound impenetrability, height, thickness, material and installation are all key factors that must be correctly executed for best performance.
