Quick answer: OSHA hearing protection requirements depend on the industry, the employee’s measured noise exposure, and whether engineering or administrative controls can reduce the hazard.
- General industry: An 8-hour time-weighted average of 85 dBA is the action level that triggers a hearing conservation program and requires employers to make suitable hearing protectors available at no cost. It does not mean every employee must automatically wear hearing protection solely because exposure reaches 85 dBA.
- Construction: OSHA’s construction noise standard uses a permissible exposure table beginning at 90 dBA for eight hours. When feasible controls cannot reduce exposure to the table limits, hearing protection must be provided and used.
Employers should measure employee exposure, reduce noise at the source when feasible, select hearing protection that provides adequate attenuation, ensure proper fit and use, and follow any state-plan, customer, project, or company requirements that are more protective than federal OSHA.
This guide provides general safety information and is not legal advice. Review current federal OSHA standards, applicable state-plan rules, company policies, project requirements, and the hearing protector manufacturer’s instructions.
What OSHA Noise Level Requires Hearing Protection?
The answer is often summarized as either 85 dBA or 90 dBA, but those numbers serve different purposes.
85 dBA: General-Industry Action Level
Under 29 CFR 1910.95, an 8-hour time-weighted average of 85 dBA is the action level for general industry. When information indicates that an employee’s exposure may reach or exceed this level, the employer must develop and implement a monitoring program.
Employees exposed at or above the action level must be included in a hearing conservation program. That program includes noise monitoring, employee notification, audiometric testing, suitable hearing protectors, training, and recordkeeping.
The employer must also make hearing protectors available at no cost to employees exposed at or above 85 dBA as an 8-hour TWA and provide a variety of suitable options.
90 dBA: General-Industry Permissible Exposure Limit
For general industry, 90 dBA as an 8-hour TWA is OSHA’s permissible exposure limit. When exposure exceeds the limits in the standard, employers must use feasible engineering or administrative controls. Hearing protection is required when those controls do not reduce the exposure enough.
OSHA requires hearing protectors to reduce exposure to at least 90 dBA as an 8-hour TWA. For employees who have experienced a standard threshold shift, the protector must reduce exposure to 85 dBA or below.
When Must Employees Actually Wear Hearing Protection?
In general industry, hearing protectors must be made available at 85 dBA, but OSHA does not require every employee to wear them solely because the action level has been reached.
Under the federal general-industry standard, the employer must ensure hearing protectors are worn when:
- Employees are exposed above the permissible limit and engineering or administrative controls do not reduce the exposure enough.
- An employee exposed at or above 85 dBA has not yet had a baseline audiogram established within the required period.
- An employee exposed at or above 85 dBA has experienced a standard threshold shift.
- A stricter employer, customer, project, facility, state-plan, or site policy requires their use.
Many employers require hearing protection throughout designated high-noise areas even when the federal rule would not independently require every employee to wear it at exactly 85 dBA. A written company policy may be more protective than OSHA’s minimum.
OSHA Construction Hearing Protection Requirements
Construction work is covered by 29 CFR 1926.52 and 29 CFR 1926.101, rather than the complete general-industry hearing conservation standard.
OSHA’s construction permissible-noise table allows the following exposure durations:
- 90 dBA: 8 hours
- 92 dBA: 6 hours
- 95 dBA: 4 hours
- 97 dBA: 3 hours
- 100 dBA: 2 hours
- 105 dBA: 1 hour
- 110 dBA: 30 minutes
- 115 dBA: 15 minutes or less
When construction employees are exposed above these limits, feasible engineering or administrative controls must be used. If those controls do not reduce exposure to the table limits, hearing protection must be provided and used.
A continuing, effective hearing conservation program is required when construction noise exceeds the permissible table. Insert-type ear protectors must be fitted or individually determined by competent persons, and plain cotton is not acceptable hearing protection.
Federal construction rules do not use the same 85 dBA hearing-conservation action level found in the general-industry standard. State-plan requirements, project specifications, or company policies may be more stringent.
Noise Exposure Is Based on Level and Duration
Noise exposure is cumulative. Employees may work around several tools or machines at different sound levels during the same shift. The combined exposure must be evaluated rather than judging each task independently.
A brief sound-level reading does not always show an employee’s full daily dose. Employers may use personal noise dosimeters, sound-level meters, task-based assessments, or other appropriate methods to determine representative exposure.
Monitoring should account for:
- Different tasks and tools used throughout the shift
- Changes in production, equipment, processes, or work location
- Intermittent and continuous noise
- Employees moving between noise zones
- Whether existing hearing protection provides adequate attenuation
- Impulsive or impact noise
Engineering Controls Come Before Hearing Protection
Hearing protection is important, but OSHA expects employers to use feasible controls to reduce excessive noise rather than relying only on earplugs or earmuffs.
Engineering Controls
Engineering controls reduce noise at its source or along the path between the source and employee. Examples may include:
- Replacing noisy equipment with quieter models
- Installing silencers, mufflers, dampening, or vibration isolation
- Using acoustic barriers, curtains, or enclosures
- Maintaining and lubricating equipment
- Increasing distance between the employee and noise source
- Isolating the operator in a sound-controlled cab or room
Administrative Controls
Administrative controls reduce the amount of time employees are exposed. Examples may include scheduling noisy work when fewer employees are present, limiting time in high-noise areas, increasing distance, or changing work practices.
Employee rotation should not be used casually because it can expose additional workers. Controls should be selected through a documented noise-control process.
Hearing Protection Devices
Hearing protectors are used when exposure remains excessive, while controls are being developed or installed, or when the work makes further reduction infeasible. The employer must select devices that provide adequate protection for the measured environment and ensure employees wear them correctly.
What Is an OSHA Hearing Conservation Program?
In general industry, a hearing conservation program is required for employees exposed at or above an 8-hour TWA of 85 dBA.
The program includes:
- Monitoring: Identifying employees and tasks exposed at or above the action level.
- Employee notification: Informing employees of monitoring results at or above 85 dBA.
- Audiometric testing: Establishing baseline audiograms and providing annual testing for covered employees.
- Hearing protectors: Providing a variety of suitable devices at no cost and replacing them as necessary.
- Fitting and supervision: Ensuring proper initial fit and correct use.
- Training: Explaining noise effects, protector selection and care, and audiometric testing.
- Recordkeeping: Maintaining required exposure and audiometric records.
Construction employers must administer a continuing, effective hearing conservation program when exposure exceeds OSHA’s construction permissible-noise table. State plans and company programs may use the more protective 85 dBA benchmark across both construction and general-industry operations.
Choosing the Right Hearing Protection
The best hearing protector is one that provides adequate attenuation, fits the employee, works with the other required PPE, and is worn correctly for the full exposure period.
Disposable Foam Earplugs
Foam earplugs can provide high attenuation when they are rolled, inserted, and allowed to expand correctly. They are compact and practical for continuous noise, but poor insertion can substantially reduce protection.
Reusable Earplugs
Reusable plugs can be convenient for employees who enter and leave noisy areas throughout the day. They should be cleaned, inspected, stored properly, and replaced when worn or damaged.
Banded Earplugs
Banded protectors are easy to put on and remove during intermittent exposure. Their actual attenuation and fit depend on the band position, ear-canal seal, and manufacturer’s instructions.
Over-the-Head Earmuffs
Earmuffs are visible and generally easier to verify from a distance. They may work well where earplug fit is difficult, but the ear cushions must seal against the head. Eyeglass temples, hair, hats, hoods, respirator straps, and other PPE can reduce that seal.
Helmet-Mounted Earmuffs
Helmet-mounted earmuffs keep hearing protection connected to compatible head protection and can be moved between active and standby positions. Compatibility must be confirmed for the exact helmet, adapter, and earmuff combination.
TPR carries helmet-mounted hearing protection for Hardknock, Securis, and other compatible helmet and hard-hat systems.
What Does NRR Mean?
The Noise Reduction Rating shown on hearing-protector packaging is a laboratory-based rating used to help estimate attenuation. It is not a guarantee that every employee will receive that exact reduction in the field.
Actual protection depends on:
- Correct product selection
- Individual ear and head shape
- Proper insertion or cushion seal
- Training and practice
- Condition and cleanliness of the protector
- Compatibility with other PPE
- Consistent wear throughout the exposure
OSHA requires employers to evaluate attenuation for the specific noise environment. Appendix B to 29 CFR 1910.95 provides accepted NRR methods based on the measuring equipment used.
For an A-weighted exposure measurement, the OSHA Appendix B method subtracts 7 dB from the labeled NRR before estimating the protected exposure. The old shortcut of simply dividing the NRR by two is not the complete Appendix B compliance method.
Because field fit varies, hearing-protector fit testing can provide a personal attenuation rating and help identify employees who need a different protector or additional fitting instruction. Employers should still ensure their compliance evaluation follows OSHA’s accepted method.
Can Hearing Protection Reduce Too Much Noise?
More attenuation is not always better. Excessive protection can make communication and warning signals difficult to hear and may cause employees to remove their protectors.
NIOSH recommends selecting enough protection to reduce exposure to approximately 75–85 dBA when practical. Selection should balance attenuation with communication, situational awareness, comfort, and consistent use.
Electronic level-dependent earmuffs and communication-rated hearing protectors may help in certain environments, but only products labeled with an NRR should be treated as hearing protection. Consumer noise-canceling headphones are not a substitute unless they are specifically rated and selected for occupational hearing protection.
When Is Double Hearing Protection Needed?
Federal OSHA does not state that dual protection automatically becomes mandatory at exactly 100 dBA for every workplace. The employer must determine whether the selected protection provides adequate attenuation for the measured exposure.
NIOSH recommends earmuffs worn over earplugs for exposure at or above 100 dBA or for impulsive sounds. Dual protection may also be needed when one device cannot reduce exposure to the required level.
When earplugs and earmuffs are worn together, their labeled NRR values are not simply added. Use an accepted method to estimate combined attenuation and verify that both devices fit correctly.
Hearing Protection and Safety Helmet Compatibility
Head protection, hearing protection, eye protection, and face protection must work together as a system. An earmuff that does not mount correctly or seal around the ear may not deliver the expected attenuation.
Before issuing helmet-mounted earmuffs, check:
- Compatibility with the helmet manufacturer and model
- Correct slot, rail, or adapter type
- Whether the cushions fully seal around the ears
- Interference from safety glasses, goggles, respirators, or facial hair
- Whether the earmuffs remain properly positioned during bending and movement
- Whether the combination affects the helmet’s electrical classification or approved configuration

Employer Hearing Protection Checklist
- Measure exposure. Use representative monitoring rather than estimating noise by how loud it sounds.
- Identify the applicable standard. Determine whether the work is covered by general industry, construction, or another OSHA standard.
- Use feasible controls. Reduce noise at the source or limit exposure before relying solely on PPE.
- Provide suitable choices. In general industry, employees must be able to choose from a variety of suitable protectors.
- Evaluate attenuation. Confirm that the selected NRR and fit are adequate for the measured environment.
- Train and fit employees. Demonstrate insertion, adjustment, inspection, cleaning, storage, and replacement.
- Check PPE compatibility. Make sure the protector works with helmets, glasses, respirators, and other equipment.
- Monitor the program. Reevaluate exposure and protection when equipment, processes, production, or work areas change.
- Document the program. Maintain required monitoring, audiometric, training, and program records.
OSHA Hearing Protection FAQs
Is hearing protection required at 85 dBA?
In general industry, 85 dBA as an 8-hour TWA triggers the hearing conservation program and requires suitable protectors to be made available at no cost. Mandatory use at that level applies in specific situations, including when the employee has not yet received a required baseline audiogram or has experienced a standard threshold shift. An employer or project may impose a stricter policy.
Is hearing protection required at 90 dBA?
At or above the federal OSHA eight-hour permissible limit, employers must use feasible engineering or administrative controls. When those controls do not reduce exposure enough, hearing protection must be used.
What is the OSHA hearing protection level for construction?
The federal construction table begins at 90 dBA for eight hours and allows shorter exposure as the noise level increases. When controls cannot reduce exposure to those limits, hearing protection must be provided and used.
Are earplugs OSHA approved?
OSHA does not generally approve individual brands or products. Earplugs are acceptable when they are suitable for the employee, properly fitted, correctly used, and provide adequate attenuation for the measured exposure.
Does OSHA require a choice of hearing protectors?
The general-industry standard requires employees to be given the opportunity to select from a variety of suitable hearing protectors supplied by the employer.
Can workers use Bluetooth earbuds as hearing protection?
Only when the product is designed and labeled as occupational hearing protection with an NRR and is selected as part of the employer’s program. Consumer earbuds or active-noise-canceling headphones should not be assumed to provide compliant hearing protection.
Is double hearing protection required above 100 dBA?
NIOSH recommends earplugs plus earmuffs at or above 100 dBA or for impulsive noise. OSHA requires adequate attenuation for the specific exposure but does not create one universal dual-protection trigger at exactly 100 dBA.
How often should hearing protection be replaced?
Replace disposable plugs after use as directed, and replace reusable plugs, bands, cushions, earmuffs, and other components when damaged, contaminated, hardened, cracked, or unable to maintain the required fit and seal. Follow the manufacturer’s instructions.
