What does an acoustic consultant do?
An acoustic consultant assesses, measures, and manages noise and vibration to ensure compliance with regulations and improve comfort in buildings and environments.

A Noise Impact Assessment (or Acoustic Report) is a mandatory technical document required by most local councils as part of a Development Application (DA). It proves that your proposed project, whether it’s a new café, a home renovation, or a commercial warehouse, will not create “offensive noise” for the surrounding community.

Councils have strict noise limits based on whether your area is residential, commercial, or industrial. We measure the “background noise” and offer acoustic recommendations for your project to stay within those legal limits.
For businesses like gyms or childcare centers, an acoustic report often determines your allowed opening hours. Without a favourable report, Council may restrict your operation hours.
If our testing shows a potential noise issue (like a loud kitchen exhaust fan), we provide “mitigation strategies” such as acoustic screens or silencers to ensure your DA is approved without delays.

While product catalogs provide data on individual materials, they don’t account for your specific “built environment.” A consultant looks at flanking paths (how sound travels through joints, ducts, and floor gaps) and the specific geometry of your space. We provide unbiased advice to ensure you don’t overspend on unnecessary products that might not solve your noise issue.
Ideally, during the initial design or planning phase. It is significantly more cost-effective to design a space with the correct partitions, layouts, and materials from the start than to retroactively “fix” a noise issue once the building is finished. Early involvement ensures compliance with local council regulations and building codes without expensive mid-construction changes.

Yes. Most Strata Schemes and Owners Corporations require a formal acoustic certificate before and after the installation of hard flooring (such as timber, hybrid, or tile). This process ensures your new floor won’t disturb the residents living below you.

 

Every building has specific “Ln,w” (impact sound) ratings that your flooring must meet. An acoustic consultant ensures your chosen underlay and floor finish are compliant with your specific building’s rules.

 

If a neighbor complains about noise after your floor is installed and you don’t have an acoustic compliance certificate, the Strata Committee can legally force you to remove the floor and reinstall carpet at your own expense.

 

We provide “Before and After” impact noise testing (tapping tests) to give you and the Strata Committee evidence of the floor’s acoustic performance
