Hearing Protection Standards

Guide to Hearing Protection Australian Standards

AS/NZS 1269 Series – Occupational Noise Management

This range of standards outlines general requirements for managing occupational noise. It includes guidelines for measuring and assessing noise emissions and exposure, implementing control measures, developing hearing protector programs, and conducting auditory assessments.

AS/NZS 1270:2002 – Acoustics: Hearing Protectors

This standard specifies the design, material, and performance requirements for conventional hearing protectors. It also includes guidance on specialist hearing protectors and outlines physical and acoustic testing procedures for compliance.

SLC80 Rating

The SLC80 rating indicates how well a hearing protector reduces noise in a controlled lab setting. However, real-world results can vary due to factors such as ear size, hearing protector size, and how well it’s fitted. Therefore, selecting a product that fits properly and is easy to use is key for effective protection.

Workplace Noise Assessments

Employers in Australia have a legal obligation to protect employees from harmful noise levels. This requires conducting a workplace noise assessment—also known as a noise survey or test—using specialised monitoring equipment to measure sound exposure and duration.

Each Australian state and territory follows its own WHS laws. Typically, these require a qualified professional to perform the assessment to ensure noise exposure remains within safe, legal limits.
