Hearing Conservation Program Overview
Why It Matters
According to the Centers for Disease Control and Prevention (CDC), Noise-Induced Hearing Loss (NIHL) is the most common work-related illness in the United States. NIHL is permanent — there is no cure. Fortunately, it is 100% preventable with proactive measures and an effective Hearing Conservation Program.
Nearly 1 in 10 workers are exposed to noise loud enough to cause hearing loss, and 7 in 10 experience moderately loud noise levels, according to the U.S. Bureau of Labor Statistics. Yet more than half of exposed workers do not wear hearing protection.
The combined cost of unprotected exposure runs into hundreds of millions of dollars annually in workers' compensation claims — not counting reduced productivity or the human toll on quality of life.

History & Context
Background
The Occupational Safety and Health Administration was signed into law on December 29, 1970 and is now a regulatory branch of the United States Department of Labor. The mission of OSHA is to "assure safe and healthy working conditions for working men and women by setting and enforcing standards by providing training, outreach and education and assistance."
An amendment to the United States Occupational Safety and Health Administration (OSHA), 29 CFR 1910.95, Occupational Noise Exposure — requiring a Hearing Conservation Program under specified circumstances — was published in the Federal Register on January 16, 1981. The amendment requires employers to implement a Hearing Conservation Program to protect employees from noise hazards in the workplace that may negatively impact hearing.
Employers have the responsibility to protect their employees from these hazards. Failure to comply with OSHA's Hearing Conservation Program requirements may result in costly penalties, and — more importantly — exposes workers to hazardous noise levels that can cause permanent occupational hearing loss.

Audiometric Testing Program
29 CFR 1910.95(g)(1)"The employer shall establish and maintain an audiometric testing program by making audiometric testing available to all employees whose exposures equal or exceed an 8-hour time-weighted average of 85 decibels."
3.
Hearing Protectors
29 CFR 1910.95(i)"Employers shall make hearing protectors available to all employees exposed to an 8-hour time-weighted average of 85 decibels or greater at no cost to the employees. Hearing protectors shall be replaced as necessary."
4.
Training Program
29 CFR 1910.95(k)"The employer shall train each employee who is exposed to noise at or above an 8-hour time-weighted average of 85 decibels and ensure employee participation in the program."
5.
Recordkeeping
29 CFR 1910.95(m)"The employer shall maintain an accurate record of all employee exposure measurements. The employer shall retain employee audiometric test records."

Compliance & Enforcement
OSHA Penalties
Non-compliance with the Hearing Conservation Program requirements can result in significant monetary penalties. Citations are typically issued per violation, and repeated or willful violations carry heavily multiplied fines.
Employers should review the current OSHA penalty schedule to understand the financial implications of non-compliance.

"Failing to protect employees from excessive noise can lead to long-term and irreversible hearing loss. Employers are required to take appropriate precautions to keep employees safe from well-known hazards."
"Earning a living should not come at the expense of hearing loss."
"Employers are liable for monitoring noise exposure and providing hearing protection. OSHA is committed to protecting workers, especially when employers fail to do so."
"Employers have the responsibility to protect the long-term health of their workers by ensuring they are enrolled in a hearing conservation program and conducting follow-up evaluations."
Common Questions
OSHA Hearing Conservation Program — FAQ
Plain-English answers to the most frequently asked questions about OSHA's hearing conservation program requirements under 29 CFR 1910.95.
What is an OSHA Hearing Conservation Program?
An OSHA Hearing Conservation Program (HCP) is a written workplace program required under 29 CFR 1910.95 whenever employee noise exposure equals or exceeds an 8-hour time-weighted average of 85 decibels. A compliant HCP must include noise monitoring, annual audiometric testing, employer-provided hearing protectors, annual training, and recordkeeping.
When is a hearing conservation program required by OSHA?
OSHA requires a hearing conservation program any time employee exposure equals or exceeds an 8-hour time-weighted average (TWA) of 85 dBA — known as the action level. The Permissible Exposure Limit (PEL) is 90 dBA over an 8-hour TWA. Employers must enroll any affected employee in the HCP regardless of how the exposure occurred.
What does 29 CFR 1910.95 require?
The standard requires employers to (1) monitor employee noise exposure, (2) provide audiometric testing, (3) furnish hearing protectors at no cost, (4) train affected employees annually, and (5) retain noise exposure and audiometric records. Failure to comply can result in OSHA citations and monetary penalties.
Who must receive audiometric testing under OSHA?
Any employee whose noise exposure equals or exceeds an 8-hour time-weighted average of 85 decibels must be offered audiometric testing at no cost. Employers must establish a baseline audiogram within 6 months of first exposure (or 1 year if a mobile test van is used) and provide an annual audiogram thereafter. Each annual test is compared to the baseline to detect a Standard Threshold Shift (STS).
How often must workplace noise monitoring be performed?
OSHA does not specify a fixed monitoring frequency, but monitoring must be repeated whenever a change in production, process, equipment, or controls increases noise exposure to the point that additional employees may need to be enrolled in the program — or where the attenuation of currently issued hearing protectors may no longer be adequate.
What hearing protection does OSHA require employers to provide?
Employers must make hearing protectors available — at no cost to the employee — to all employees exposed to an 8-hour time-weighted average of 85 decibels or greater. Employees must be given a choice from a variety of suitable protectors, and the protectors must be evaluated for adequate attenuation for the specific work environment. OSHA uses the Noise Reduction Rating (NRR) with a derating method to estimate real-world attenuation — see NRR derating.
What are the penalties for failing to implement a hearing conservation program?
OSHA penalties for hearing conservation program violations are issued per violation under the agency's published penalty schedule. Serious and other-than-serious violations carry maximum penalties that are adjusted annually for inflation; willful or repeated violations are multiplied substantially. Always consult the current OSHA penalty schedule.
How long must hearing conservation records be retained?
Under 29 CFR 1910.95(m), employers must retain noise exposure measurement records for at least 2 years and audiometric test records for the duration of the affected employee's employment. Records must be made available upon request to employees, former employees, their representatives, and the Assistant Secretary of Labor.
