Hearing Conservation and Noise · v1.0.0 · October 21, 2026
Learn how noise can harm your hearing at work. This track covers the construction rules. Learn to check the work, use controls and fit hearing protection. The employer adds the actual task plan and any hearing tests. The two industry tracks have different test rules. Allow about 35–50 minutes, at your own pace.
Actual construction task/noise assessment, effective controls, suitable protection, individual inserted-device fitting or determination by competent persons, task instruction, safe communication and any applicable adopted audiometric program remain separate. Confirm State Plan, client and employer additions.
Level-duration examples
The following table reproduces the listed level-duration pairs in Table G-16 and construction Table D-2. GI noise-dose computation also uses mandatory Appendix A. This is not a personal work clearance. Combined exposures, peaks, actual shifts and governing criteria require the proper assessment.
| Duration per day, hours | Sound level, dBA slow response |
|---|---|
| 8 | 90 |
| 6 | 92 |
| 4 | 95 |
| 3 | 97 |
| 2 | 100 |
| 1.5 | 102 |
| 1 | 105 |
| 0.5 | 110 |
| 0.25 or less | 115 |
1. Use the construction noise rules
By the end: Choose the right legal track and identify any additional employer policy.
A construction crew has finished a safety course. Its next task uses a loud saw. The crew still needs a review of the noise, working controls, suitable protection and fitting instruction. A course pass does not make the task ready.
Federal construction work uses 1926.52 and 1926.101 for noise and hearing protection. Under 1926.21(b)(2), the employer must also teach workers how to recognize and avoid unsafe conditions. Choose the rules for the actual work and place, not only the company name.
Do not copy the whole general-industry program into construction as if the laws were the same. Its 85 dBA program trigger, yearly training and detailed hearing-test deadlines are not all stated in the federal construction rule. Construction still has noise limits, controls, program and protection duties.
An employer can choose a broader plan. It may require protection sooner, yearly training and hearing tests. Ask the employer which plan applies to your work. State or client rules may add duties that need a separate check.
This course teaches worker knowledge. It does not make you a noise assessor, a competent person or a hearing-test technician. Use narrated lessons only in a safe, quiet place. The employer adds the real task and device instruction.
Basis: 1926.21(b)(2), 1926.52, 1926.101; OSHA interpretation 1983-03-29
2. Noise can harm hearing before you notice
By the end: Recognize possible harm and respond to a concern without waiting for a test.
A worker leaves a loud task with ringing ears. Sounds seem dull. The crew says this happens to everyone. Treat the report as a warning to review the exposure and protection. Do not use it as proof that the work is safe.
Loud noise can damage the small structures that help you hear. Damage can build up over time. A very loud event can also cause harm. Noise-related hearing loss can be permanent. Getting used to a sound does not mean your ears are protected.
Noise can also make speech, alarms and other warning sounds harder to hear. Work with the employer to plan safe communication. A worker should not have to choose between keeping protection on and hearing a safety instruction.
Report ringing, muffled hearing, pain or a sudden hearing change through the workplace route. Move out of harmful exposure safely and seek appropriate medical advice promptly for a sudden change or injury. This course does not diagnose the cause. Do not wait for the next yearly test to report a new problem.
Loud hobbies and some chemical exposures can add to hearing risks. Tell the appropriate health professional about relevant concerns privately. Keep clinical details out of crew discussions and course messages.
Basis: 1926.21(b)(2), 1926.52; OSHA/NIOSH hearing-loss guidance
3. Read exposure as level plus time
By the end: Explain Table D-2 and why periods of noise must be considered together.
A saw, a breaker and nearby equipment all add to a worker’s day. Check the actual time and level for the work. A quick reading in a quiet break is not the exposure from cutting or breaking concrete.
Table D-2 lists permissible level-duration pairs measured in dBA at slow response. Examples are 90 dBA for eight hours, 95 dBA for four hours and 100 dBA for two hours. Use the full table and actual assessment rather than treating one pair as a safe limit for every shift.
For two or more periods at different levels, the construction rule uses an equivalent exposure factor. Add each actual duration divided by its table duration. A total greater than one exceeds the permissible level. For example, two hours at 95 dBA uses one-half, and one hour at 100 dBA uses one-half. Together they reach one before any more exposure is added.
Rapid changes with peaks one second apart or less are treated as continuous under the rule. Impact or impulse noise has a separate recommendation not to exceed 140 dB peak. A peak value and a dBA average are not the same measure. Uncertain high-peak work needs technical review.
A hearing-conservation program is required where sound levels exceed the values in the construction rule. An employer may use a more protective trigger. Do not turn a single reading below a table value into permission to ignore the task, duration, peaks or other noise.
Basis: 1926.52(a), (c)–(e), Table D-2
4. Assess changing construction work
By the end: Provide the real task details needed to plan noise protection.
The tools, materials and crews on a job site change. Yesterday’s reading on another floor may not match today’s work. Tell the employer about loud tools, impact work, enclosed spaces and nearby trades. Explain how long each task lasts.
The employer needs sound exposure data to apply the rule and choose controls. A person with the right skills chooses the test method, settings and work conditions to measure. A phone app may flag a concern. Its screen alone does not show the noise from the whole job.
Describe what really happens during setup, full-load work, idle time and cleanup. Other equipment may run after your own tool stops. Noise from another employer can still reach your crew. Use the site plan to coordinate the work.
Use interim protection while an unclear risk is being checked. Report a new tool, a longer task, a failed control or a warning that cannot be heard. The supervisor and assessor must review the change before treating the old plan as good enough.
Some employers add the general-industry monitoring and worker-information process to their construction plan. Follow that plan if it applies. Do not claim that every detail of 1910.95 automatically becomes a separate federal construction duty.
Basis: 1926.21(b)(2), 1926.52(a)–(d)
5. Plan quieter construction work
By the end: Apply feasible controls and verify they remain effective.
A crew may be able to use a quieter tool or method. It may keep people farther from a loud source or use a suitable barrier. Good maintenance can also help. Plan controls before bringing people into the noise. Check that they work during the real task.
When noise exceeds Table D-2, the employer must use feasible engineering or administrative controls. If these do not bring noise within the table limits, suitable PPE must be provided and used. Under 1926.101, ear protective devices are required when it is not feasible to reduce level or time to the table values.
Limits on time must count each worker’s combined noise. Moving people from one noisy task to another does not always lower their dose. Assign someone to check the actual tasks, other sources and time limits.
A continuing, effective hearing-conservation program is required when the rule’s values are exceeded. A box of plugs and an attendance sheet alone do not make that program effective. Link the noise data, controls, fitting, correct use and follow-up.
If a barrier moves, an enclosure opens or a tool changes, stop relying on the old plan. Restore the controls or have a safe alternative checked. Involve the worker who raised the concern in checking the fix.
Basis: 1926.52(b), (d)(1); 1926.101(a)
6. Choose protection for the actual noise
By the end: Explain why a package rating alone does not establish protection.
A worker finds a box of earplugs with a large Noise Reduction Rating, or NRR. That rating does not prove how much protection this worker gets. The employer must select suitable protection for the actual noise, worker and task.
Earplugs fit in the ear canal. Earmuffs seal around the ears. Each type has benefits and limits. Plugs may suit tight work spaces but depend on correct insertion and clean handling. Muffs can be easier to see and check, but glasses, hair or other equipment can break the seal. Comfort matters because protection must be used correctly for the exposure.
Attenuation means reduction in sound. The noise assessor evaluates whether a device provides enough reduction in the specific environment. Do not subtract the label NRR directly from any sound reading. Do not add plug and muff ratings together. Dual protection needs its own evaluation.
Consumer noise-canceling earbuds are not a substitute for evaluated hearing protection. Music volume and a quiet feeling are not proof of adequate attenuation. Use the actual employer-approved model, instructions and replacement supply.
Plain cotton is not an acceptable protective device under 1926.101(c). Ask the employer to resolve a missing or unsuitable protector before exposure.
Basis: 1926.52(b); 1926.101(a), (c); employer selection process
7. Fit protection with the rest of your PPE
By the end: Explain and demonstrate the fitting steps for the actual assigned device.
A worker puts on muffs, then adds safety glasses with thick arms. The seal changes. Protection must work with all of the required equipment. Do not remove eye protection to fix a hearing-protection conflict. Ask for a suitable, compatible solution.
Follow the instructions for the exact device. For roll-down foam plugs, the instructions often include rolling the plug, positioning the ear, inserting it and holding it as it expands. These steps do not apply to every type of plug. Use the actual manufacturer method and the trainer’s guidance. Never force a device into a painful ear.
For muffs, check cushions, headband adjustment and a full seal around each ear. Keep hair, clothing and other items out of the seal. Do not bend, modify or interchange parts without approval. A helmet-mounted muff must suit the actual helmet and mounting system.
Construction rules require inserted ear protectors to be fitted or determined individually by competent persons. They must be able to spot existing and predictable hazards and have authority to correct them promptly. Completing this course does not make you that competent person. Have the employer arrange the actual individual fitting.
Individual attenuation fit testing can help check real protection. It may be part of the employer’s program. This core does not describe a universal federal annual hearing-protector fit-test requirement. A lesson check is not an actual fitting or an attenuation test.
Basis: 1926.101(b), 1926.32(f); 1926.21(b)(2); actual manufacturer instructions
8. Use, inspect and care for protection
By the end: Keep suitable protection in use and handle a defect or communication problem safely.
Fit protection before entering the designated noisy task or area. Keep it in place throughout the exposure required by the work plan. Brief periods without protection can greatly reduce the protection gained over the task. Move to a safe, quieter place before removing it.
Check the actual device before use. Look for damaged cushions, a weak or bent band, dirty or worn plugs, missing parts and signs that the fit has changed. Follow the manufacturer’s cleaning and replacement instructions. Some plugs are single use. Others can be cleaned only by an approved method.
Store reusable protection where it stays clean, dry and protected from damage. Do not use solvents, heat or makeshift repairs unless the instructions permit them. Obtain a suitable replacement when the device cannot be used correctly. Report a shortage rather than starting the task with damaged equipment.
If an alarm, radio message or instruction cannot be understood, follow the agreed safe communication and stop-work plan. Do not lift a muff or remove a plug while staying in the harmful noise. The team may need a different approved communication system, signals or a quieter discussion point.
The employer must review changes in noise, tools, tasks, duration or PPE. A familiar protector is not proof that a changed task is covered. Report the change and confirm controls before continuing.
Basis: 1926.21(b)(2), 1926.52, 1926.101; actual employer/device instructions
9. Understand hearing tests in the actual program
By the end: Describe the purpose of audiometry without inventing construction deadlines.
A hearing test measures hearing thresholds. A quiz checks knowledge. If the employer’s program includes hearing tests, the real test still needs a suitable provider, test space, tools and follow-up. A course pass cannot replace it.
In a typical test you wear test earphones, listen for tones and respond as told. The baseline is the starting test. Later tests can show changes. Ask the provider to explain any unclear step or equipment problem.
The detailed general-industry baseline and yearly timetable is not automatically the federal construction timetable. Follow the rules and employer plan that apply to the job. Follow the provider’s instructions. Ask whether your employer requires baseline and yearly tests and which provider to use.
Use the named private route for test results or a new symptom. Do not post an audiogram or other clinical details in the course discussion. Keep the actual test record separate from the LMS knowledge record.
If a provider finds a hearing change, arrange the plan’s follow-up. Review noise, controls and protection. Do not wait for course renewal to report ringing, muffled hearing, pain or sudden change. An earlier normal result does not make unprotected noisy work safe.
Basis: 1926.52(d)(1), 1926.21(b)(2); adopted employer program; 1910.95(g) as a separate model
10. Show the task is ready and keep accurate evidence
By the end: Connect actual instruction, fitting, changes and record responsibilities.
Before noisy work, name the task, tools, nearby sources and time limits. Check the current noise data. Confirm that controls work, the right protectors are ready and they fit. Check the warning and communication plan. Resolve a missing step before starting.
The instruction must help you recognize and avoid the unsafe conditions in your own work. Explain the plan in your own words. Show how to fit the device with your other PPE. For inserted devices, the competent person must do the required individual fitting or determination.
Update instruction when work, equipment or understanding changes so the worker can use the current plan. A State Plan, client or employer rule may require yearly instruction. Do not claim that these federal construction provisions state one yearly interval for every worker.
Keep the online result, task instruction, fitting and observed-use evidence separate. Keep any hearing-test records through the private process. The employer chooses the controlled record process under the duties that apply. Do not give all training and health records one made-up retention period.
If a control fails, a device no longer fits, new noise starts or warnings cannot be understood, use the safe pause and reporting route. Record the change, fix and recheck. Help the team correct conditions that make protection hard to use.
