Hearing Conservation Program: OSHA Noise Requirements
Noise-induced hearing loss is permanent, gradual, and completely preventable. When workplace noise crosses a threshold, OSHA requires a hearing conservation program. Here is what it involves.
QUICK ANSWER
OSHA requires a hearing conservation program when noise exposure reaches or exceeds an 8-hour time-weighted average of 85 decibels. The program includes noise monitoring, annual audiometric (hearing) testing, hearing protection made available and required above certain levels, worker training, and recordkeeping. The goal is to catch and prevent hearing loss early, since it cannot be reversed once it occurs.
When the Program Kicks In
The trigger is an 8-hour time-weighted average noise exposure of 85 decibels, the action level. At that point the employer must implement a hearing conservation program. Because hearing loss is gradual and painless, workers rarely notice it happening, which is why monitoring and testing matter.
- Noise monitoring: measure exposures to know who is at risk.
- Audiometric testing: a baseline and annual hearing tests to detect early shifts.
- Hearing protection: made available at the action level and required at higher levels.
- Training: on noise hazards, protection, and the testing program.
85 dB
85 decibels over 8 hours is the action level. It is not that loud in the moment, which is exactly why noise-induced hearing loss sneaks up on workers.
Hearing protection is part of the broader PPE program and OSHA requirements. See safety and operations VR training.
WE BUILD THIS IN VR — THE PRIME VR
We build noise and hearing-protection training into VR, where workers learn to recognize noise hazards, fit protection correctly, and understand why it matters, in realistic high-noise environments. It drives the consistent use of protection that prevents irreversible hearing loss.

At what noise level is a hearing conservation program required? +
OSHA requires a hearing conservation program when noise exposure equals or exceeds an 8-hour time-weighted average of 85 decibels, known as the action level. Above that, monitoring, audiometric testing, and protection requirements apply.
What is audiometric testing? +
Audiometric testing is periodic hearing testing that establishes a baseline and tracks a worker hearing over time. It detects early shifts in hearing so the employer can intervene before loss becomes significant, since noise-induced hearing loss is permanent.
Is noise-induced hearing loss reversible? +
No. Noise-induced hearing loss is permanent and cumulative, which is why prevention through monitoring, protection, and early detection is the entire point of a hearing conservation program.
