Noise management

Home > Risk management > Occupational safety and health

Noise-induced hearing loss is one of the most common occupational health issues. Every year thousands of workers are exposed to workplace noise hazards that result in preventable hearing loss.

Noise in the workplace can also be highly distracting. It can limit communication, affect safety, and reduce worker performance and overall productivity.

Exposure to excessive noise levels can cause permanent hearing damage that cannot be corrected by surgery or a hearing aid. Even short-term exposure to loud noise can cause a temporary change in hearing.

Short-term effects such as ringing in the ears may go away after leaving the noisy area. However, repeated exposure to noise hazards can lead to permanent tinnitus or hearing loss.

In addition to hearing damage, noise hazards can:

  • Create physical and psychological stress
  • Reduce productivity
  • Interfere with communication and concentration
  • Contribute to workplace accidents and injuries by making it difficult to hear warning signals or instruction

Reducing noise levels at the source provides the most effective way of protecting workers' hearing, as well as providing numerous other benefits.​

WA Legislation

In Western Australia, the exposure standard for noise set out in the Occupational Safety and Health Regulations 1996 is:

  • A daily noise exposure level of 85 dBA over an 8 hour period
  • A peak noise level of 140 dBC

The Workers' Compensation and Injury Management Act 1981 sets out the requirements for audiometric testing of workers who work in a prescribed workplace.  A prescribed workplace is a workplace where a worker is receiving, or likely to receive, a noise level of:

  • An L peak of 140 dB
  • A representative of 90 dB over an 8 hour period

Conducting a noise assessment will determine if work areas, or activities performed, fall into the category of a prescribed workplace.


How can LGIS assist?

LGIS have approved noise officers who specialize in conducting noise and exposure assessments in all workplace environments.

Members will receive a tailored report outlining the findings and recommendations.

In addition, at the request of the member, LGIS can assist in the development of supporting plans, policies and procedures.
