Workplace Audiometric Testing or Hearing Testing – NSW Legislation
PCBUs (persons conducting a business or undertaking) must provide audiometric testing to any worker frequently required to use personal protective equipment (PPE) for hearing protection. This applies when workplace noise levels exceed:
- LAeq,8h of 85 dB(A) – the eight-hour equivalent continuous A-weighted sound pressure level
- LC,peak of 140 dB(C) – the C-weighted peak sound pressure level
These levels are the workplace exposure standards as defined by the WHS Regulation.
Why Your Business Needs Workplace Audiometric Testing & Hearing Screening
Workplace audiometric testing is essential for protecting your workers’ hearing and staying compliant with WHS legislation. If your employees are exposed to noise levels above 85 decibels, regular hearing assessments are a legal requirement under the NSW WHS Regulation 2017.
Nearly 30% of Australian workers are exposed to dangerous noise levels at work. Left unchecked, this can lead to discomfort, fatigue, and permanent hearing damage.
SESA provides on-site audiometric testing and hearing assessments to help you protect your team and comply with WHS obligations. We also conduct comprehensive workplace noise surveys to identify risk areas and determine if ongoing testing is required.
Benefits of audiometric testing for your business include:
- Early detection of hearing loss from workplace noise exposure
- Legal compliance with Safe Work NSW and WHS regulations
- Improved safety for staff working in noisy environments
- Reduced workers’ compensation claims linked to noise-induced hearing loss
- Data for monitoring workplace noise risks over time
By investing in onsite audiometric assessments, you’re protecting your workforce, reducing liability, and showing a clear commitment to workplace health and safety.

Workplace Audiometric Testing – Significant Threshold Shift & Abnormal Thresholds
Significant Threshold Shift Detected by Hearing Test
A threshold shift as noted in Safe Work Australia Code of Practice, refers to a shift in the auditory threshold and can be temporary or permanent, resulting in temporary or permanent hearing loss respectively. Any confirmed threshold shift should lead to action as described in AS/NZS129.4 Section 9.
A significant threshold shift is defined as:
- a shift in average threshold at 3000, 4000 and 6000 Hz greater than or equal to 5 dB; or
- a shift in mean threshold greater than or equal to 10 dB at 3000 and 4000 Hz; or
- a change in mean threshold greater than or equal to 15 dB at 6000 Hz; or
- a threshold shift greater than or equal to 15 dB at 500, 1000, 1500 or 2000 Hz; or
- a threshold shift greater than or equal to 20 dB at 8000 Hz.
Abnormal Thresholds Detected by Hearing Test
Normal hearing thresholds are in the range of 0 – 25 dB hearing level (dB HL). Thresholds that are greater than 25 dB HL are said to be outside the normal range and indicate that a hearing loss is present. There are typical patterns of hearing loss, sometimes associated with the cause of the hearing loss.
Thresholds that are either outside the normal range of hearing or atypical for a type of hearing loss are considered to be abnormal.
When thresholds are abnormal, more attention is needed in order to determine the best approach to managing the hearing loss and worker.
