Construction Noise Exposure AssessmentSydney & Greater Sydney
Sydney construction sites are among the noisiest workplaces in the country. Dense urban construction — CBD tower builds, apartment construction, road and rail infrastructure — means multiple high-noise activities operating simultaneously on constrained sites.
Sydney Local Context
Sydney's constrained urban construction sites create unique noise exposure conditions. Multiple trades work in close proximity, compounding noise levels. Night works for infrastructure projects generate sustained noise exposure for shift workers.
Major Project Types in Sydney
Key Hazards
Primary exposure hazards requiring monitoring in Sydney.
Power tool noise
Angle grinders, circular saws, concrete saws, impact drills, and rotary hammers generate impulsive and continuous noise at levels consistently exceeding 100 dB(A). Short-duration tasks can contribute significantly to daily noise dose.
Heavy plant and equipment
Piling rigs, concrete pumps, cranes, excavators, and compressors generate broadband noise that affects both operators and nearby workers. Octave band analysis is required for effective HPD selection in mixed-frequency environments.
Impulse noise
Cartridge-fired fastener tools, hammering, and pneumatic breakers produce impulse noise that can exceed the 140 dB(C) peak exposure limit in a single event. Peak noise assessment requires specific instrumentation.
Common Analytes
Substances typically included in occupational hygiene sampling proposals for this sub-category.
Typical Worker Groups
Common similar exposure groups (SEGs) assessed for this sub-category.
Regulatory Context
The WHS Regulation requires PCBUs to ensure noise exposure does not exceed the WES of 85 dB(A) LAeq,8h or 140 dB(C) peak. Where noise exceeds these levels, a hierarchy of controls must be applied. Audiometric testing is required for workers with significant noise exposure. The Managing Noise and Preventing Hearing Loss at Work Code of Practice provides guidance.
SafeWork NSW Context
SafeWork NSW includes noise as a priority hazard in construction industry campaigns. Audiometric testing providers must be NATA-accredited.
