Introduction: Why Hearing Protection Still Matters in 2025
Noise-induced hearing loss (NIHL) is one of the most common and preventable occupational hazards. Whether you're on a construction site, in a manufacturing plant, or working in aviation or mining, consistent exposure to high noise levels can permanently damage your hearing. That’s why OSHA continues to enforce strict hearing protection standards.
This guide explains the latest OSHA regulations for 2025, how to assess workplace noise, and what steps you need to take to protect your employees—and your business—from costly violations and health risks.
What Is OSHA's Hearing Protection Standard?
OSHA’s regulations for occupational noise exposure are defined under:
- 29 CFR 1910.95 (General Industry)
- 29 CFR 1926.52 (Construction)
Key limits include:
- Permissible Exposure Limit (PEL): 90 dBA over an 8-hour time-weighted average (TWA)
- Action Level (AL): 85 dBA over an 8-hour TWA—requires implementation of a Hearing Conservation Program (HCP)
Steps to Meet OSHA Hearing Protection Requirements
1. Conduct a Noise Assessment
Use a sound level meter or dosimeter to measure workplace noise. Assess noise levels across different tasks, equipment, and locations throughout the day.
2. Determine if Action Is Required
If noise exceeds 85 dBA (TWA), employers must:
- Implement a written Hearing Conservation Program
- Provide baseline and annual audiometric testing
- Offer a variety of hearing protection devices (HPDs)
- Train employees on risks and proper use of HPDs
- Keep records of noise exposure and hearing tests
3. Provide Appropriate Hearing Protection Devices
Offer workers a choice of properly rated HPDs, including:
- Foam earplugs – Disposable, soft, and effective
- Reusable earplugs – Cost-effective and eco-friendly
- Earmuffs – Ideal for intermittent use or extreme noise
- Canal caps and banded plugs – Convenient for short-term use
4. Train Employees
OSHA requires annual training that covers:
- How hearing loss occurs
- Risks of workplace noise exposure
- How to properly insert earplugs or wear earmuffs
- Limitations and maintenance of HPDs
5. Monitor and Maintain Records
Maintain accurate documentation for:
- Noise measurements
- Employee audiograms
- HPD fit-testing (if applicable)
- Annual training sessions
What Is a Hearing Conservation Program (HCP)?
It’s a formal plan that employers must implement when employees are exposed to noise at or above the action level. It includes:
- Noise monitoring
- Employee notification
- Free annual hearing tests
- HPD selection and fitting
- Training and education
- Recordkeeping
Tips for Choosing the Right HPDs
- Check the Noise Reduction Rating (NRR)—the higher, the better
- Match HPD type to job function and comfort preferences
- Use dual protection (earplugs + earmuffs) for noise over 100 dBA
- Ensure workers understand fit and wear time requirements

Frequently Asked Questions (FAQs)
1. What’s the difference between PEL and Action Level?
PEL (90 dBA) is the legal noise limit over 8 hours. Action Level (85 dBA) is a lower threshold where protective measures must begin, including implementing a Hearing Conservation Program.
2. Are employers required to pay for hearing protection?
Yes. OSHA mandates that employers provide hearing protection at no cost to employees exposed above the action level.
3. Can workers choose their own type of hearing protection?
Yes. OSHA recommends offering a variety of options so employees can select what’s most comfortable and effective for their work environment.
4. How often should hearing tests be conducted?
OSHA requires a baseline test upon enrollment in an HCP, followed by annual tests to detect any shifts in hearing ability.
5. Are earplugs enough protection for very loud environments?
Sometimes. For environments over 100 dBA, dual protection (earplugs plus earmuffs) may be required to meet adequate noise reduction levels.
Conclusion: Hear Today, Work Tomorrow
Hearing loss is permanent, but compliance with OSHA’s hearing protection standards can prevent it. By assessing noise levels, educating workers, and providing effective protection, you’ll ensure a safer and more productive work environment.
