Occupational Noise Assessments
Our occupational noise assessments use state-of-the-art equipment to map your site's noise levels accurately, identify where your workers are most at risk, and give you the clear, actionable recommendations you need to manage that risk effectively. Conducted on-site at your workplace, anywhere across NSW.
Understanding Occupational Noise Assessments
An occupational noise assessment measures noise levels across your workplace to identify where workers may be exposed to hazardous noise. Using professional sound level meters and personal noise dosimeters, we assess worker exposure, compare the results against Australian Standards and provide practical recommendations to help you manage the risk.
Our reports identify areas requiring action, determine whether hearing protection is required and provide the information you need to support compliance with workplace health and safety requirements.
What to Expect
1
Before we arrive on site, we'll discuss your workplace with you — understanding your layout, the types of machinery and processes involved, the number of workers and their roles, and any areas of existing concern. This scoping conversation helps us plan the assessment to cover all relevant noise sources and exposure scenarios.
2
Our technician arrives at your workplace and conducts systematic noise measurements across your site using calibrated sound level meters. Measurements are taken at different locations, at different times of day, and under different operating conditions — capturing both continuous and intermittent noise sources accurately.
3
For a complete picture of individual worker exposure, we attach personal noise dosimeters to selected workers for the duration of their shift. Unlike static measurements, dosimeters follow the worker — capturing their actual cumulative noise exposure as they move between areas, operate different equipment, and complete different tasks throughout the day.
4
Back in the office, our noise assessment expert analyses all measurement data against regulatory exposure standards and Australian Standards requirements. This analysis identifies which areas and roles exceed the exposure standard, quantifies the level of risk, and determines what controls are required.
5
You receive a detailed, clearly written assessment report covering all measurement findings, a comparison against regulatory limits, identification of high-risk areas and roles, and tailored recommendations for noise control — spanning engineering controls, administrative controls, and fit-for-purpose hearing protection requirements for each zone of your workplace.
6
This is where we go beyond just handing over a document. Our occupational noise expert Callum will personally walk you through the report, answer your questions, and make sure you leave the conversation with a clear understanding of your obligations and a practical action plan. We're here to help you act on the findings, not just document them.
How We Work
Why NSW Businesses Choose Hayden Health & Safety for Occupational Noise Assessments
Our occupational noise assessments are led by Callum, our dedicated noise assessment specialist. Every report is personally reviewed, and every client gets a direct conversation with Callum to walk through findings and recommendations. You're not getting a data dump — you're getting expert guidance.
Many providers offer one or the other. We conduct both static area measurements and personal dosimetry monitoring to give you the most complete and accurate picture of noise exposure across your site. This dual approach means nothing gets missed — and your recommendations are based on how your workers actually experience noise, not just how loud your machines are.
We don't stop at measurement. Our reports include practical, prioritised recommendations for noise control — from engineering solutions through to the specific class of hearing protection required in each area of your site. You'll know exactly what to do, in what order, and why.
Noise assessments and audiometric testing are two sides of the same coin. One tells you what your workers are exposed to; the other tells you what effect it's having. Many of our clients book both together, and our reporting is designed to support both programs — giving you a complete, integrated noise management picture.
We travel to your workplace, anywhere in NSW — whether you're running a manufacturing plant in Newcastle, a council depot in Tamworth, or a civil construction site in regional Western NSW. No need to send your team anywhere or pull them off the job for longer than necessary.
Our occupational noise assessments are conducted in accordance with Australian Standards and NSW WHS legislation. Using calibrated equipment and recognised assessment methods, we provide accurate, audit-ready reports you can rely on to support compliance and protect your workers.
Compliance & Regulations
Under the NSW Work Health and Safety Regulation 2025, employers must identify and manage the risks associated with hazardous workplace noise. Where workers are exposed to noise at or above the exposure standard, or there is a reasonable likelihood they may be, a noise assessment helps determine the level of risk and identify the most appropriate control measures. It also supports related obligations, including providing suitable hearing protection, conducting audiometric testing where required, and maintaining appropriate records.
We provide complete assessment documentation that satisfies your compliance record-keeping obligations and supports any future audit or regulatory review.
Conducted as soon as practicable once noise-generating work commences, or when a noise hazard is identified
A full compliance noise assessment is required at least every five years under the NSW Code of Practice
New machinery or equipment is introduced; work processes change significantly; workplace layout is altered; or audiometric testing results suggest existing controls may be insufficient
