Acoustic Report for NSW Development Applications
An acoustic report, also called a noise impact assessment, shows council that your project will not unreasonably disturb its neighbours, or that your building will be quiet enough inside for the people who will live or work there. It is one of the most common reasons a DA is held up with a request for more information.

Two types of acoustic report
The first deals with noise your project makes, such as air conditioning and plant, patrons, music, deliveries, car park movements and industrial processes. The second deals with noise coming onto your site, such as traffic, trains and aircraft, which matters for apartments, boarding houses and childcare centres on busy roads or near rail corridors. Some projects need both.
What the report is measured against
For noise from commercial and industrial sources, assessors work to the NSW EPA Noise Policy for Industry (2017), which sets limits for the neighbours' nearest homes. Construction noise follows the Interim Construction Noise Guideline. For roads, the NSW Road Noise Policy applies. For housing near busy roads and railways, the Transport and Infrastructure SEPP and the Department's guideline for development near rail corridors and busy roads set internal limits, commonly 35 dB(A) in bedrooms at night and 40 dB(A) in living areas. Childcare centres have their own acoustic assessment guidance, and venues also have to deal with the licensing authority.
Which projects need one
Cafes, restaurants, bars and function venues, gyms, childcare centres, schools, medical centres with plant, industrial and warehouse uses, car washes, and residential buildings near busy roads or rail. Council can also ask for one when a neighbour objects to noise.
What affects the price
Fees start from $1,800 + GST. The price depends on the number of noise sources, whether noise monitoring on site is needed, how many receivers are nearby, and whether the report must include mitigation design. We coordinate an acoustic consultant suited to the use and fix the fee after a free scope check.
Why concept stage is cheaper
A consultant can often solve a noise problem with a plant location, a wall, a setback or an operating hour change before the plans are drawn. After lodgement, the same fix means redrawing. We check your operating hours against the assessment so you are not approved for hours you cannot actually trade.
How it works
Sensitivity and criteria check
2 to 3 days
Confirm the background noise environment and the applicable EPA criteria for the site.
Assessment
1 to 2 weeks
Noise sources modelled against the criteria, with mitigation identified where needed.
Report and integration
3 to 5 days
Findings integrated with the operating hours and plant selection proposed in the DA.
What we take off your hands
What EHUP handles
- Coordinating an acoustic consultant suited to your specific use
- Assessing noise from plant, patrons, deliveries or industrial processes against EPA criteria
- Advising on mitigation (setbacks, hours, acoustic treatment) before it becomes a condition of consent
- Cross-checking acoustic findings against operating hours proposed elsewhere in the DA
What you don't have to deal with
- A noise condition that makes the approved operating hours unworkable
- An acoustic assessment that ignores how quiet the surrounding area already is
Frequently asked questions
Which projects need an acoustic report?
Venues, childcare, plant heavy uses, industrial sites, and housing near busy roads or rail.
Why does the surrounding area matter?
The limits are set by the nearest homes and the existing background noise, so a quiet street has stricter limits than a main road.
Can an acoustic report change my operating hours?
Yes. If the assessment shows late hours cannot meet the criteria, council may limit them in the consent.
Can we fix a failed report?
Often. Plant relocation, enclosures, setbacks and hours changes are the usual fixes.

Specialist Reports
Most applications of any size need reports from specialists outside town planning.
Contaminated Land Assessment
If your site has any history of industrial, agricultural chemical or waste-related use, council will likely require a staged contamination assessment before development can proceed - starting with a Preliminary Site Investigation (PSI), which escalates to a Detailed Site Investigation and a Remediation Action Plan only if contamination is actually confirmed.
Arborist Report
An arborist report assesses the health, significance and structural condition of trees on or near your site, and recommends which should be retained, removed or protected during construction.
Geotechnical Report
A geotechnical report tells you what is under your site and what that means for your footings, retaining walls and excavation.
Construction Management Plan
A construction management plan, or CMP, is the document council reads to decide whether your build will disrupt the street.
