Audiometric Testing Sydney & NSW

Audiometric testing is a critical workplace health requirement for employees exposed to hazardous noise. We provide compliant audiometric testing across Sydney and NSW, conducted onsite in a suitable quiet environment to ensure accurate and reliable results.

Our service supports employers in meeting WHS regulations and AS/NZS 1269.4 Audiometric Assessment standards, helping prevent long-term noise-induced hearing loss (NIHL) and ensuring ongoing workplace compliance.

What is Audiometric Testing?

Audiometric testing is a hearing assessment used to measure a worker’s ability to hear sounds across a range of frequencies. It is used to detect early signs of noise-induced hearing loss (NIHL) caused by prolonged exposure to workplace noise.

The test establishes a baseline hearing level and tracks changes over time to ensure workplace noise controls and hearing protection measures remain effective.

Why Audiometric Testing is Important

Workplace noise exposure can cause permanent hearing damage if not properly controlled. Audiometric testing is a key part of a hearing conservation and workplace health surveillance program.

Regular testing helps:

  • Detect early signs of hearing loss before it becomes permanent

  • Monitor the effectiveness of hearing protection programs

  • Identify Temporary Threshold Shifts (TTS)

  • Support WHS compliance obligations

  • Reduce long-term compensation and liability risks

Early identification allows employers to take corrective action before irreversible damage occurs.

WHS Requirements for Audiometric Testing in NSW

Under NSW Work Health and Safety regulations, employers must provide audiometric testing for workers who are frequently exposed to hazardous noise levels.

Testing is generally required when exposure exceeds:

  • 85 dB(A) averaged over 8 hours

  • 140 dB(C) peak noise levels

Required testing schedule:

  • Baseline test within 3 months of starting noisy work

  • Repeat testing at least every 2 years

These requirements ensure ongoing monitoring of worker hearing health and compliance with WHS obligations.

Onsite Audiometric Testing Process

Audiometric testing is conducted onsite at your workplace in a suitable quiet indoor environment such as a meeting room or office space that meets background noise requirements.

The process includes:

  1. Verification of suitable quiet testing conditions

  2. Calibration of audiometric equipment

  3. Individual hearing assessments for each worker

  4. Recording of hearing thresholds across frequencies

  5. Comparison against baseline results where applicable

Each test takes approximately 10–15 minutes per worker, minimising disruption to operations.

Temporary Threshold Shift (TTS) Monitoring

Audiometric testing also helps identify Temporary Threshold Shifts (TTS), which are early indicators of excessive noise exposure in the workplace.

Detecting TTS allows employers to:

  • Review and improve noise control measures

  • Assess the effectiveness of hearing protection

  • Prevent progression to permanent hearing loss

  • Strengthen workplace safety systems

Personal Hearing Protection Effectiveness

Audiometric testing can also be used to assess the effectiveness of hearing protection when used in the workplace.

This helps determine:

  • Whether hearing protection is providing adequate attenuation

  • Whether PPE is being correctly fitted and used

  • Whether additional controls are required under WHS guidelines

  • A hearing test, also known as audiometric testing, measures a person’s ability to hear different sounds and frequencies. it is used to detect early signs of hearing loss, particularly in noisy work environments.

  • Workers who are regularly exposed to high noise levels (85 dB over 8 hours or peak of 140dB), such as in construction, manufacturing, mining, and industrial settings, require hearing testing as part of workplace health monitoring.

  • Hearing testing helps identify early signs of noise-induced hearing loss, allowing employers to implement controls and protect workers before permanent damage occurs.

  • Hearing tests are required for workers exposed to hazardous noise levels. a baseline test should be conducted within 3 months of starting work, followed by monitoring at least every 2 years, or more frequently depending on risk.

  • A hearing test typically takes around 10 to 15 minutes per person, making it quick and efficient for workplace testing.

  • If a hearing test indicates potential hearing loss, further assessment may be recommended and workplace controls should be reviewed to reduce noise exposure.
