Managing noise risks

The source path receiver model

We’ve produced a series of resources to help you understand your duties around managing the risks of noise, including using the source path receiver model, providing workers with hearing protection if risk remains, and making sure your workers are trained.

Elimination

The most effective way to reduce noise levels at your work is to eliminate the noise source.

Isolation

Isolation involves blocking the noise source or the noise path so it doesn’t reach the worker.

Absorption

Absorption is used to reduce levels of reflected sound or sound created at a source.

Acoustic enclosures

Use enclosures fitted around all or part of a machine to reduce noise.

Reducing impact noise

Impact noise happens when objects hit a hard surface, such as when they are dropped from height or when they hit against another object.

Damping

Damping lowers noise levels by reducing air turbulence and mechanical vibration. If used correctly, damping is one of the most effective ways of reducing noise levels.

Vibration noise control

Machines mounted on large hard surfaces can generate noise when they vibrate. Use these strategies to help you reduce noise levels caused by vibration.
