Our state-of-the-art testing vans travel to your site anywhere in Australia, allowing employees to complete their hearing test quickly and comfortably without leaving the workplace.
This flexible, on-site model minimises disruption, ensures consistent test results, and makes it simple for businesses to meet audiometric testing requirements under Australian work health and safety laws.
For more than 35 years, JTA Health, Safety & Noise Specialists has helped Australian organisations protect workers from noise-induced hearing loss and maintain compliance with national standards.
Learn about Daily Noise Exposure Limits
Our approach to audiometric assessment is built around JTA’s proven Detect. Protect. framework, ensuring your business stays compliant while protecting your people.
We identify noise sources and compliance issues through our occupational noise assessments (ONA’s), supporting better occupational noise management and control planning.
Learn about Daily Noise Exposure Limits and how they apply to your work environment.
Workers exposed to noise identified in the ONA must have audiometric testing within three months of starting and every two years after that.
Through this testing, our consultants detect early changes in hearing thresholds before they become permanent, helping you act quickly and effectively.
Testing also involves scheduling re-testing when exposure exceeds the exposure standard, resulting in continued compliance with AS/NZS 1269.4:2014 and a safer, healthier workforce.
Workers are at risk of hearing loss whenever they are exposed to noise that exceeds the national exposure standard, which is:
Yes, otoscopy is an important part of the Audiometric Testing process. It involves examining the outer ear and ear canal using an Otoscope to ensure there are no obstructions, infections, or abnormalities that could affect the hearing test results. This step helps ensure the accuracy of the audiometric assessment.
An audiometric assessment, or hearing test, checks how well an employee hears different sounds and volumes.
It establishes a baseline at the start of employment and tracks any changes through ongoing monitoring.
Under Australian workplace laws, business owners (persons conducting a business or undertaking) must test employees exposed to loud noise levels (over 85 dBA).
This is a key requirement for work health and safety compliance. They must also have a follow-up assessment within 12 months.
After that, employees need regular re-testing to check for any changes in their hearing.
JTA offers both initial and follow-up audiometric tests.
This helps employers understand each worker’s test results and compliance status.
Our testing identifies noise-induced hearing loss early, allowing for prompt investigation, prevention, and corrective control measures.
Importantly, our Reminder Recall System means that we will inform you when you are due for your next round of testing so that you remain compliant.
Our mobile testing vans are purpose-built to deliver accurate results in any environment.
They are acoustically controlled and equipped for pure tone audiometry and bone conduction testing, ensuring precision and comfort for every participant.
All testing is performed by trained health professionals in accordance with AS/NZS 1269.4:2014.
Our specialists understand both the technical and legislative aspects of audiometric testing requirements, ensuring your program meets every element of the work health and safety framework and national occupational safety and health standards.
Each worker’s audiometric test results are compared with their baseline data to detect any shift in hearing thresholds.
Results are classified as Normal, Significant Shift, or Overdue, and summarised for easy compliance tracking.
Employees receive individual results explaining their hearing thresholds and any identified type of hearing loss, while employers receive aggregated compliance reports.
If a shift is detected, the employee is required to see an audiologist for a more detailed assessment.
Audiometric Testing helps you comply with noise regulations by providing a clear record of an employee's hearing ability over time. The testing:
Comply with all Australian audiometric testing requirements
Detect early signs of noise-induced hearing loss
Demonstrate compliance with AS/NZS 1269.4:2014
Provide staff with confidence in your work health and safety program
Obtain accurate, traceable test results with minimal downtime
Strengthen your occupational noise management system
Build a reliable long-term record of workforce hearing health
By combining reliable audiometric assessment with clear interpretation, JTA helps organisations maintain safe workplaces and protect employees from preventable hearing loss.
Employers must make sure that all workers exposed to loud noise levels have an audiometric test.
This test measure should happen within the first three months of exposure and again within 12 months to check for any changes.
If audiometric testing shows a significant change in hearing, a noise assessment should be conducted to determine if exposure is above the standard and confirm if current control measures are effective.
JTA offers both audiometric assessments and occupational noise assessments, giving you a full solution for hearing conservation and compliance.
Starting on 1 December 2026, Australia will have a new Workplace Exposure Limit (WEL) framework, replacing the current Workplace Exposure Standards (WES).
For the first time, certain airborne contaminants will carry an “OTO” (ototoxicity) notation, recognising their potential to damage hearing when combined with hazardous chemicals.
This change does not alter audiometric testing procedures, but it highlights the need to manage exposure to both noise and harmful substances.
JTA’s integrated Detect. Protect. approach helps employers address these overlapping risks by coordinating audiometric and airborne exposure monitoring in line with Safe Work Australia and guidance from the National Institute for Occupational Safety and Health (NIOSH) and the Institute for Occupational Safety and Health (IOSH).
Our Detect. Protect. approach ensures every assessment delivers clear insight and measurable outcomes.

Hearing loss depends on how loud a noise is, how long someone is exposed to it and, to some extent, individual susceptibility. The frequency or pitch can also affect hearing loss; high-pitched sounds are more damaging than low-pitched ones. Hazardous noise (loud, continuous exposure to noise) affects the functioning of the inner ear and can cause temporary hearing loss. If exposure continues continuously over a period of time, the ear will gradually lose its ability to recover and the hearing loss will become permanent. Hearing loss can also occur suddenly if a worker is exposed to a very loud impact or explosive sounds.
Depending on the intensity of the noise and the duration of exposure, hearing loss can range from a small shift in the threshold at which sounds at different frequencies can be detected to total deafness.
Noise-related injuries are most common in the manufacturing and construction industries. Some examples of those most at risk are:
Exposure to some chemicals, called ototoxic substances, can also result in hearing loss. People who work with noise and ototoxic substances are at greater risk of hearing loss. If a worker is exposed to these chemicals, the noise exposure standard is reduced from 85 decibels to 80 decibels or below. Work activities that combine ototoxic substances and noise include:
The general rule for determining if noise is a problem in your workplace is if employees have to raise their voice to communicate at a distance of one metre and/or employees have a temporary reduction in hearing or ringing in the ears after leaving work for the day. You should conduct a formal noise assessment if you think noise might be a problem. This will help you:
Read more about an Occupational Noise Assessment
An Occupational Audiologist is a health care professional who assesses and manages noise exposure in the workplace to prevent hearing loss. They are qualified to interpret audiology test results and to assist the employer in making appropriate decisions.
The best way to control the risk of hazardous noise is to eliminate the noise completely. If you can’t do that, WHS/OHS Regulations recommend you:
Personal protective equipment (PPE) can be used if all other controls do not reduce the noise levels to an acceptable level. The appropriate level of hearing protection to be used must correspond with the level of noise exposure. Common types of hearing PPE are:
When selecting hearing protection, you must ensure that the level of noise entering the worker’s ears is reduced to below the exposure standard for noise. If a worker needs to frequently wear personal hearing protection to protect them from noise above the noise exposure standard, you must provide the worker with regular Audiometric Testing.
