Air traffic controllers spend their shifts wearing communication headsets through which ATC radio traffic, pilot readbacks, and coordination calls are delivered continuously. While the ambient environment in TRACON and en-route facilities is relatively quiet, the sustained audio level delivered through headsets — particularly during high-traffic periods with overlapping transmissions — creates an occupational noise exposure that is entirely headset-mediated and often unmonitored. The CDC estimates 22 million U.S. workers face hazardous occupational noise each year, and air traffic controllers are a meaningful segment of that total.
Soundtrace provides automated audiometric testing, real-time noise monitoring, and HPD fit testing in a unified platform for employers across the industries where air traffic controllers work.
FAA employs most U.S. air traffic controllers as federal employees under 29 CFR 1960.70, the federal agency OSHA noise standard that mirrors the occupational noise requirements of 1910.95 at 85 dBA TWA. Headset audio levels in ATC operations have been documented at 80–92 dBA average, with peaks during busy traffic periods reaching 95+ dBA — potentially meeting the action level for controllers with sustained high-traffic workloads.
Measured Noise Exposure Levels
| Operation | Typical Noise Level | OSHA Max Duration |
|---|---|---|
| ATC headset (average traffic, en-route) | 78–86 dBA | Full shift |
| ATC headset (peak traffic, TRACON) | 82–92 dBA | Peak traffic periods |
| ATC headset (simultaneous transmission) | 88–98 dBA | During overlap |
| Tower cab ambient (open window) | 80–92 dBA | Full shift |
| Tower cab (near PA/interphone) | 84–92 dBA | During use |
| TRACON / ARTCC facility ambient | 60–72 dBA | Low — non-headset |
| Ground vehicle / airfield operations (tower) | 88–100 dBA | During exterior duties |
OSHA Requirements
Under 29 CFR 1910.95, employers must implement a hearing conservation program when any worker's 8-hour TWA meets or exceeds 85 dBA. Required elements:
- Noise monitoring to establish documented TWA for each exposed worker
- Baseline audiogram within 6 months of first qualifying exposure (preceded by 14 hours of quiet)
- Annual audiograms compared to baseline for standard threshold shift (STS) detection
- Hearing protection provided at no cost in a variety of types and styles
- Annual training covering noise hazards, HPD use, and audiometric results
- Recordkeeping per 1910.95(m) — noise measurements, audiograms, training documentation

Federal Employee OSHA Coverage: 29 CFR 1960.70
FAA air traffic controllers are federal employees covered by the Federal Agency OSHA program under Executive Order 12196 and 29 CFR 1960.70. FAA is required to maintain an occupational safety and health program that meets or exceeds the requirements of 1910.95, including noise monitoring, audiometric testing, and hearing protection for employees exposed at or above 85 dBA TWA.
FAA's Occupational Safety and Health (OSH) Program manages hearing conservation compliance for ATCS. However, the occupational health literature on ATC hearing loss documents audiometric changes consistent with headset-mediated noise exposure — suggesting that existing program monitoring may not fully capture the headset-delivered noise dose that controllers receive.
See: Federal Workplace Hearing Conservation: 29 CFR 1960 Guide
Workers' Compensation Exposure
Occupational hearing loss WC claims are routinely filed years or decades after the causative exposure. Without a documented baseline audiogram, employers cannot establish what hearing the worker had at hire — making every dB of loss present at claim filing presumptively attributable to the current employer.
A complete audiometric record, maintained from day one of employment, is the only document that allows an employer to separate their noise exposure period from everything that came before and after.

Frequently Asked Questions
Yes, when their 8-hour TWA meets or exceeds 85 dBA. Many air traffic controllers in active operations regularly meet or exceed this threshold. OSHA 1910.95 requires employers to enroll qualifying workers in a hearing conservation program including audiometric testing, hearing protection, training, and recordkeeping.
Noise-induced hearing loss (NIHL) is the primary occupational hearing condition. It typically presents first as a 4,000 Hz notch on audiometry before progressing to involve 3,000 and 6,000 Hz. The loss is permanent and irreversible once established, which is why early detection through annual audiometry is critical.
Yes. Occupational hearing loss is compensable in all U.S. states when a worker can establish that their hearing loss was caused or contributed to by workplace noise exposure. Claims are routinely filed years or decades after the exposure period. Employers with complete audiometric records and documented noise measurements are far better positioned to contest causation or support apportionment.
A compliant hearing conservation program includes noise monitoring to document TWA, baseline and annual audiograms, hearing protection at no cost, annual training, and complete recordkeeping. Individual HPD fit testing — measuring each worker's personal attenuation rating (PAR) — is the only method that verifies actual protection rather than assuming label NRR performance.
Hearing protection must provide adequate attenuation for the actual measured TWA. Individual fit testing verifies each worker's personal attenuation rating (PAR). At higher exposure levels — above 100 dBA — double protection combining earplug and earmuff is often required to achieve adequate attenuation.
