Noise Exposure Calculator, Australia Safe Work
Free workplace noise exposure calculator. Enter noise levels in dB(A) and exposure durations to calculate your daily personal noise exposure (LEP,d), percentage of daily dose, and compare against OSHA PEL (90 dB), UK HSE (85 dB), and EU Directive 2003/10/EC (80/85 dB) limits.
Calculate workplace noise exposure against Safe Work Australia's model Work Health and Safety Regulations. Australia uses an 8-hour equivalent continuous sound level (LAeq,8h) of 85 dB(A) as the exposure standard.
Australian WHS Regulations set the noise exposure standard at LAeq,8h of 85 dB(A) and a peak noise level of 140 dB(C). This aligns with the UK/EU standard and uses the 3 dB exchange rate. The model regulations have been adopted in most Australian states.

Frequently Asked Questions, Noise Exposure Calculator in Australia Safe Work
What is Australia's noise exposure standard?↓
Safe Work Australia's model WHS Regulations set the noise exposure standard at an LAeq,8h of 85 dB(A), which is equivalent to an 8-hour average sound level. The peak noise standard is 140 dB(C). Employers must manage noise risks if exposure could reach the standard. Engineering controls must be used before hearing protectors where practicable.
Which Australian states have adopted the model WHS Regulations?↓
The model WHS Act and Regulations have been adopted by: Commonwealth (federal workplaces), NSW, Queensland, South Australia, Tasmania, ACT, and Northern Territory. Victoria and Western Australia have their own separate WHS legislation, though the underlying noise standards are broadly similar. Each state has its own WHS regulator (e.g. SafeWork NSW, WorkSafe Queensland).
Does Australia require audiometric testing for noise-exposed workers?↓
Yes. Under the model WHS Regulations, employers must ensure audiometric testing is provided to workers who are frequently required to use hearing personal protective equipment in noisy environments. Testing must be done within 3 months of first being required to use hearing PPE and thereafter at least every 2 years.
