How loud is your worksite?
That’s a question employers should be able to answer with a number.
Did you know that more than 22 million workers in the United States are exposed to noise levels that put their hearing at risk every year?
A hearing conservation program must be implemented at, or above, a TWA of 85 dBA, as per OSHA.
When noise levels reach 85 decibels (dBA) or more over an 8-hour shift, OSHA requires employers to maintain a hearing conservation program to protect their workers. Keep in mind that a decibel level of 85 is not hard to reach — even a regular household blender even registers at 88.
A hearing conservation program helps employers prevent hearing loss, reduce costly workers’ compensation claims and boost productivity by creating a safer, healthier workplace.
Here, we’ll show you how you can build a program that works—keeping your team safe and your company compliant for years to come.

What Is a Hearing Conservation Program and Why Do You Need One?
A hearing conservation program is designed to prevent noise-induced hearing loss by identifying high noise areas and controlling exposure.
In the U.S., OSHA’s noise standard (29 CFR 1910.95) mandates that any workplace where employees are exposed to 85 dBA or higher averaged over 8 hours must have a program in place.
This includes:
– monitoring noise levels,
– providing hearing protection,
– conducting audiometric testing,
– training employees, and
– maintaining records.
With 22 million exposed workers and about $242 million spent annually on hearing loss claims, having an effective program is both a legal obligation and a smart investment in your workforce’s health.
How to Accurately Monitor Noise Levels
Your hearing conservation program starts with proper noise monitoring. Use calibrated sound level meters or noise dosimeters to measure the noise exposure across your workplace.
Both area noise monitoring (measuring overall workplace noise) and task-specific measurements (like jackhammer use) are important. Repeat measurements whenever processes or equipment change to ensure noise control remains effective.
Free apps like the CDC’s Sound Level Meter can help in preliminary assessments, but professional equipment is recommended for compliance testing.
See NIOSH/CDC’s Guidelines on Noise and Hearing Loss: Understand Noise Exposure.
Selecting the Right Hearing Protection Devices (HPDs)
Hearing protection is essential, but it’s not one-size-fits-all. Offer several types of PPE, like earmuffs and earplugs, so workers can find what fits best. In 2025, the big update is individual fit testing.
NIOSH now recommends employers conduct quantitative fit tests for hearing protectors to ensure they provide the necessary attenuation.
This means relying less on manufacturer Noise Reduction Ratings (NRR) alone and more on how well the device fits each worker’s ear.
Fit testing improves protection efficacy and worker comfort, increasing the likelihood that PPE is used consistently and correctly.
Audiometric Testing and What It Reveals
Audiometric testing is required for workers exposed to 85 dBA or higher, with a baseline exam done within 6 months of first exposure and annual follow-ups. These tests measure hearing thresholds across key frequencies (500 to 6000 Hz) for each ear separately.
Audiogram results are compared year to year to detect any standard threshold shift (STS), indicating hearing loss. If a shift is detected, employers must take additional steps, which may include refitting hearing protection, retraining workers, or referring them to medical evaluation.
Properly administered audiometric testing and assessment help catch early hearing damage before it worsens.
Training and Evaluating Your Hearing Conservation Program
Regular training ensures that employees understand the dangers of noise exposure and how to use hearing protection properly. In addition to general awareness, your training should include instructions on fit testing and interpreting personal attenuation ratings (PAR).
Programs must also be evaluated periodically to see if workers are experiencing hearing loss despite controls being in place. If so, noise controls or audiometric protocols might need an upgrade.
Documentation and record-keeping of noise monitoring, training sessions, audiometric tests, and program evaluations are vital for OSHA compliance.
Key Takeaways
Creating a less disruptive and more productive occupational health plan is possible with a good hearing conservation program.
By staying current with today’s standards – especially focusing on noise monitoring, individual fit testing, and effective training – you protect your team’s hearing and reduce costly workers’ compensation claims. Need assistance?
