Noise Assessments

What are Noise Assessments for?

Noise Assessments are conducted by Attune Workplace Hearing, and performed in accordance with AS 1269 standards, WHS and OHS Regulations, and the Code of Practice for Managing Noise and Preventing Hearing Loss at Work.


Attune Workplace Hearing’s qualified Noise Officer will visit your site, conduct the noise measurements, and provide a detailed comprehensive report to your company highlighting the below objectives.

In accordance with Section 4.1 ‘When should a risk assessment be conducted?’ in Code of Practice for Managing Noise and Preventing Hearing Loss at Work:

Noise Assessments will help you:

  • Identify which workers are at risk of hearing loss
  • Determine what noise sources and processes are causing that risk
  • Identify if and what kind of noise control measures could be implemented
  • Check the effectiveness of existing control measures

The objectives of a Noise Assessment report are to:

  1. Identify all people likely to be exposed to noise above the exposure standard for noise. This will involve the evaluation of ‘LAeq,8h (A-Weighted)’ and measurements of peak noise levels ‘LC,Peak (C weighted)’.
  2. Obtain information on noise sources and work practices that will help your workplace decide what measures should be taken to reduce noise.
  3. Check the effectiveness of measures taken to reduce exposure to noise (ie: engineering noise control measures and administrative noise control measures)
  4. Help in the selection of appropriate personal hearing protection.
  5. Delineate hearing protection level areas.


Types of Noise Assessments:

Preliminary and Detailed Noise Assessment – Conducted if no previous noise assessment has been carried out, or previous assessments are more than 5 years old. A detailed assessment is required in areas where there is a likelihood of exposure to excessive noise.

Follow-up Noise Assessments:

  1. Five Year Noise Assessment – A follow-up noise assessment shall be carried out at least every five years to monitor changes in noise exposure (ie: from deterioration of equipment, changes in work procedures, introduction of new production processes, and effectiveness of engineering noise controls).
  2. Supplementary Noise Assessment – In areas where new plant has been introduced, where work practices have changed, and in areas where regular monitoring is required to check changes in noise exposure due to seasonal or workload related factors, a supplementary noise assessment shall be carried out on only part of the workplace.
