Occupational Noise Assessment

Don’t let excessive noise
become a deafening problem

No matter what size your workplace is or what activities are carried out there, excessive noise can be a major issue leading to hearing loss. If a noise is continuous and intrusive, if employees need to raise their voices to speak to each other or if workers use noisy power tools or machinery then noise could be a safety hazard at your workplace.

OHS/WHS regulations require you to assess and control the risk of noise induced hearing loss and to monitor it at a minimum of every five years once a noise risk is identified. Our Occupational Noise Assessment will help you to ensure the health and safety of your employees exposed to noise by determining how loud the noise is and how long they are exposed to it by using the latest noise monitoring equipment. The assessment will use noise measurement to provide information on the risks and an action plan for controlling the noise.

JTA Noise employs the use of dosimetry as standard for all occupational noise assessments. This ensures a more accurate result when determining noise exposure over a period of time, rather than basing assessments on assumptions of exposure.

Our on-site Occupational Noise Assessments are conducted with no impact on productivity and include:

Personal sound exposure measurements (dosimetry)
Individual noise measurements at worker positions and equipment
Octave band analysis (where appropriate)
Prescription of hearing protection
Suggested engineering noise controls
Full written report
Colour-coded noise map

Once identified, noise risks can often be controlled with simple measures such as:

Providing hearing protection
Introducing different or quieter processes and equipment
Using engineering controls like isolating equipment or fitting silencers
Erecting barriers and screens to block the direct path of sound
Reducing vibration (damping)
Reducing time spent in noisy areas
Positioning noise sources further away from workers
Using absorptive materials within the building to reduce reflected sound

JTA Noise has conducted thousands of noise assessments Australia wide, ranging from owner-occupied small businesses to large multi-nationals. Sites assessed through noise monitoring include mines, quarries, construction sites, distribution centres, packing halls, food manufacturing, engineering/fabrication, maintenance/workshops, major hazard facilities, printing halls, road works and slaughterhouses.

JTA’s team of acoustic consultants service all Australian cities including Melbourne, Sydney, Canberra, Brisbane, Adelaide, Perth, Darwin and Hobart, also now servicing New Zealand.

If you require training for your staff, we provide Noise Training on a regular basis and can customise an in-house training program to suit your business. JTA also provides Audiometric Testing in mobile booths at your premises.
