What is Audiometry Testing?
Summary: Audiometry testing is a hearing evaluation that measures how well someone can hear sounds at different frequencies and volumes. In workplace settings, it’s used to establish a hearing baseline and monitor changes over time—helping employers detect early signs of hearing loss before they become permanent.
Some workplace hazards are hard to miss: A broken guardrail, a slippery floor, a faulty tool. These are the kinds of risks that tend to get immediate attention. But not every hazard is that visible. Some of the most damaging risks in industrial spaces and on job sites are ones you can’t see at all. Noise is one of them.
Prolonged exposure to loud machinery, tools, and environments can cause gradual hearing damage that workers may not notice until it’s already significant. And once hearing loss occurs, it’s often permanent. That’s why OSHA established standards around specific industries and noisy worksites to conserve employees’ hearing ability.
Audiometry testing is a key step that must be performed regularly to give employers and employees a clear picture of their hearing health over time, making it possible to catch early changes and act before they become serious concerns.
What is audiometry testing?
An audiometry test is a standardized hearing evaluation that measures how well a person can hear sounds at different frequencies and volumes. During the test, a trained professional uses specialized equipment to present a series of tones through headphones. The person being tested indicates when they can hear each sound, and the results are recorded on an audiogram—a visual chart that shows hearing ability across a range of pitches.
In occupational settings, audiometry testing serves two key purposes: establishing a baseline for new employees and monitoring changes to the baseline over time.
Why is hearing testing important for employees?
Even as hearing loss is one of the most common occupational health concerns, it’s largely preventable with the right precautions in place. Workers in industries like construction, manufacturing, mining, and transportation are well familiar with the steps taken to protect and monitor hearing.
Here’s why routine audiometry testing matters:
- It identifies changes early. Noise-induced hearing loss typically develops gradually. Regular testing makes it possible to identify shifts in hearing before they reach a point where they significantly affect someone’s quality of life.
- It supports preventative action. When hearing changes are detected early, both employees and employers can take steps to reduce further damage. This might mean reviewing the use of hearing protection, adjusting noise exposure levels, or modifying work practices.
- It influences workplace safety. Hearing loss doesn’t just affect someone’s ability to hear conversation, it can also impact situational awareness, communication, and the ability to detect warning signals.
- It confirms whether protection measures are working. Hearing protection equipment is only effective if it’s appropriate for the environment and used correctly. Regular audiometry testing helps employers evaluate whether current measures are working as expected.
- It demonstrates a commitment to employee wellbeing. When hearing protection is not required for OSHA compliance, it demonstrates that the employer values hearing health and is taking actions to help employees protect it. That kind of commitment can go a long way in building trust and supporting a positive workplace culture.
Who should have regular audiometry testing?
Employees who are regularly exposed to noise levels at or above OSHA’s threshold should have their hearing monitored on an ongoing basis. This includes workers who operate loud machinery, work in environments with consistent background noise, or use power tools as part of their daily role.
If you’re unsure whether your worksite is under OSHA’s hearing regulations, a Work-Fit specialist can help assess your workplace noise levels and recommend appropriate actions for compliance.
