Achieve Workplace Safety: OSHA Compliance with Audiometric Testing

Share article

Compliance Guide·9 min read·Updated 2025

OSHA 1910.95 is the federal standard governing workplace noise and hearing conservation for general industry. Compliance is not a single action — it is an ongoing program with seven interdependent elements, each independently citable. This guide explains exactly what compliance requires and how it is achieved in practice.

Soundtrace is designed to deliver OSHA 1910.95 compliance for industrial facilities — integrating every required program element into a single platform that eliminates the documentation gaps and scheduling failures that drive citations.

Compliance Is a System

OSHA 1910.95 compliance cannot be achieved by addressing one program element in isolation. Noise monitoring, audiometric testing, HPD selection, training, and recordkeeping are interdependent — a gap in any one element undermines all the others.

Who OSHA 1910.95 Applies To

OSHA 1910.95 applies to any general industry employer where employees are exposed to noise at or above the action level of 85 dB(A) as an 8-hour TWA. There is no size threshold — a 15-person manufacturing shop and a 5,000-person plant are subject to identical requirements. The standard also applies when noise exposures are uncertain — if there is reason to believe the action level may be reached, OSHA expects monitoring to confirm or rule it out.

Exposure LevelOSHA RequirementCommon Industries
Below 85 dB(A) TWANo HCP required; general duty clause still appliesOffices, warehouses (low noise)
85–90 dB(A) TWAFull HCP required; HPDs offered but not mandatoryLight manufacturing, food processing
Above 90 dB(A) TWAFull HCP required; engineering controls and mandatory HPD useHeavy manufacturing, utilities, mining surface areas

▶ Bottom line: If any worker’s daily TWA at your facility may reach 85 dB(A), OSHA expects you to know — and the only way to know is noise monitoring. Operating without monitoring in a facility with obvious noise sources is itself a citation risk.

Element 1: Noise Monitoring

Under 1910.95(d), employers must institute a monitoring program when there is reason to believe any employee’s noise exposure may equal or exceed the action level. The monitoring program must:

  • Use sound level meters or personal noise dosimeters that meet ANSI S1.25 or S1.4 specifications
  • Integrate all noise levels from 80 dB(A) to 130 dB(A) — not just levels above 90 dB(A)
  • Be repeated when there have been production, process, equipment, or control changes that may alter exposure levels
  • Include employees in the process — 1910.95(e) requires employers to notify monitored employees and allow them or their representative to observe monitoring

Monitoring data must be retained for at least 2 years under 1910.95(m)(2) and must be available to employees, their designated representatives, and OSHA.

▶ Bottom line: An outdated noise survey from 5 years ago — predating equipment changes, line expansions, or shift restructuring — is not a current noise monitoring program under 1910.95(d). Inspectors will check whether significant changes have occurred since the last survey.

Element 2: Audiometric Testing Program

The audiometric testing requirements under 1910.95(g) are the most administratively complex element of the standard. The employer must:

  • Provide baseline audiograms to all workers at or above the action level, within 6 months of first qualifying exposure (14-hour quiet period required)
  • Provide annual audiograms to all enrolled workers within 12 months of the previous test
  • Have results reviewed by a qualified audiologist or physician
  • Determine Standard Threshold Shifts and take required follow-up actions within 21 days
  • Retain audiometric records for the duration of each employee’s employment
Most Cited Element

Missed annual audiogram deadlines — caused by mobile vendor scheduling gaps — are consistently among the top OSHA 1910.95 citations by volume. Each missed deadline is a per-employee Serious citation up to $16,550.

▶ Bottom line: Audiometric testing compliance is not a point-in-time event — it is a rolling obligation with a 12-month deadline per employee. A facility with 300 enrolled workers has 300 individual compliance deadlines to manage.

Element 3: Hearing Protection Devices

Under 1910.95(i), employers must make a variety of HPDs available to all workers exposed at or above the action level, at no cost to the employee. Selection and use requirements:

  • HPDs must be adequate to reduce worker noise exposure to below 90 dB(A) TWA (or 85 dB(A) for workers with confirmed STS)
  • Workers who have experienced an STS must use HPDs — they are no longer optional at the action level after STS
  • Employers must ensure proper HPD fit — 1910.95(i)(5) requires the employer to provide training in HPD use and fitting
  • HPD adequacy must be verified using appropriate NRR derating or individual fit testing

Workers with confirmed STS are subject to a higher protection standard: their HPDs must reduce noise exposure to at or below 85 dB(A) TWA, not just 90 dB(A).

▶ Bottom line: Issuing an HPD is not the same as ensuring it is adequate. OSHA 1910.95(i)(3) requires HPDs to reduce sound levels to acceptable levels — which requires either NRR calculation with appropriate derating or individual fit testing to verify actual attenuation.

Element 4: Annual Training

Under 1910.95(k), employers must provide annual training to every employee enrolled in the hearing conservation program. The training must cover all four content areas under 1910.95(k)(1): noise effects on hearing, HPD types and attenuation, HPD fitting and care, and audiometric testing procedures. Training that covers some but not all of these topics is noncompliant regardless of duration.

Training must be provided at the time of initial job assignment to a noise-hazardous role and annually thereafter — new hires cannot wait for the next cohort training session.

▶ Bottom line: Generic safety orientation that mentions hearing protection does not satisfy 1910.95(k). The training must specifically cover all four required content areas and must be documented with attendance records that demonstrate topic coverage.

Element 5: Recordkeeping

OSHA 1910.95(m) establishes specific retention requirements for all program records:

Record TypeRetention Period
Noise exposure measurement records2 years
Audiometric test records (all audiograms)Duration of employment
Audiometric calibration records2 years
OSHA 300 Log hearing loss entries5 years

All records must be made available to employees, their designated representatives, and OSHA upon request within the timeframes specified in 29 CFR 1910.1020. The access obligation is a compliance requirement independent of the retention obligation.

▶ Bottom line: Audiometric records must be retained for the duration of employment, not just while the employee is active. A worker who leaves and returns 10 years later should still have their historical audiograms on file.

Element 6: Employee Information Access

Under 1910.95(l), employers must make available to affected employees and their representatives all relevant information about the hearing conservation program, including:

  • Monitoring results that indicate exposure at or above the action level
  • Each employee’s audiometric test results
  • Information about the hearing conservation program and this standard

Employees have the right to observe noise monitoring under 1910.95(e). Failure to provide required access is a standalone citation under 1910.95(l).

▶ Bottom line: Employee access rights under 1910.95 are substantive, not procedural. Workers are entitled to their own audiometric data and to understand what it means — programs that treat audiometric results as internal-only documentation are out of compliance.

What an OSHA Inspection Examines

During a hearing conservation inspection, OSHA compliance officers typically examine:

Inspection FocusWhat They Look ForCitation Risk If Missing
Noise monitoring recordsCurrent survey; updated after process changesSerious
Enrolled employee listAll workers above action level enrolledSerious (per worker)
Baseline audiogramsPresent for all enrolled workers; 14-hr quiet period documentedSerious
Annual audiogramsWithin 12 months for all enrolled workersSerious (per worker)
STS recordsDeterminations documented; notifications within 21 daysSerious
HPD selection documentationNRR adequate for exposure levels; workers with STS at higher standardSerious
Training recordsAnnual; all four topics; within 12 months per employeeOther-Than-Serious to Serious

▶ Bottom line: OSHA inspectors follow a standard protocol for hearing conservation inspections. The gaps they most consistently find — outdated noise surveys, missed annual audiograms, late STS notifications, inadequate training documentation — are the same gaps that a systematic internal audit would identify first.


Frequently asked questions

What are the seven elements of an OSHA-compliant hearing conservation program?
OSHA 1910.95 requires: noise monitoring, audiometric testing (baseline and annual), hearing protection provision and enforcement, HPD training, annual employee education, recordkeeping of all elements, and employee access to program information and records.
What is OSHA’s action level for noise?
The action level is 85 dB(A) as an 8-hour TWA. Workers at or above this level must be enrolled in the HCP. The permissible exposure limit is 90 dB(A) TWA.
How does OSHA enforce hearing conservation requirements?
OSHA enforces 1910.95 through programmed inspections, complaint-driven inspections, and Regional Emphasis Programs that proactively target high-noise industries regardless of complaint history.
What is the 2025 penalty for an OSHA hearing conservation violation?
Serious violations carry up to $16,550 per violation. Willful and repeat violations carry up to $165,514. Because 1910.95 covers multiple independent elements, a single inspection can produce total penalties of $50,000–$150,000.
How does audiometric testing satisfy OSHA compliance?
Audiometric testing satisfies 1910.95(g) by establishing baseline thresholds, detecting STS through annual comparison, triggering required follow-up, and creating the documentation record that demonstrates program operation in any enforcement or litigation proceeding.
