Noise Obligations

Our Residential Noise Obligations flowchart provides a quick, and easy to use, one page guide to what you need to do to comply with residential noise requirements under OHS/WHS regulations around Australia.

How DDEG Can Help

Our Residential Noise Assessment will help you ensure the health and safety of tenants exposed to noise. It will determine how loud the noise is and how long tenants are exposed to it by using the latest noise monitoring equipment.  We use dosimetry as standard for all Residential Noise Assessments as this ensures a more accurate result and less work for building management authorities. Without dosimetry, residential noise exposures need to be calculated by determining where the tennants are throughout their stay.


Noise Assessment Includes:

  • Personal sound exposure measurements (dosimetry)

  • Individual noise measurements at tenant positions and of equipment

  • Octave-band analysis of noise sources to verify if the hearing protection utilised is appropriate

  • Colour-coded noise maps of your building

  • Compliance audit of signage, hearing protection and implementation of noise controls

  • Measurement of noise exposure levels and comparison to legislative requirements

  • Recommendations for appropriate hearing protection

  • Suggested engineering noise controls

  • Comprehensive report and action plan with practical control measures

The Benefits

  • Awareness of noise hazards and actions required by state law

  • Safe work environment with the correct PPE for employees

  • Peace of mind that legal risks are minimised

  • Long term hearing protection for your tenants

  • Compliance and the avoidance of penalties

Your Duty in Relation to Residential Noise Assessments

As a building management authority you must identify, assess and control the noise risk to your tenants and landlords. OHS/WHS Regulations stipulate that building management have a duty of care to ensure that:

  • Tenants/ Landlords are not exposed to noise which can harm their health and safety

  • Hearing protection and signage is provided if noise is over the Noise Exposure Standard

Once a noise risk has been identified, you must carry out an Occupational Noise Assessment within the building, and every 5 years at a minimum.

Your Duty in Relation to Residential Noise Assessments

If changes are made to your building that can affect noise exposure, you’re required to carry out another assessment to determine how the noise risk has changed. Changes may include;

  • New machinery

  • Alterations to procedures and shifts

  • Building renovations
