Flight attendants spend their working careers in aircraft cabins where jet engine noise, cabin pressurization systems, and passenger ambient sound create a continuous low-to-moderate occupational noise environment. While cabin noise levels are generally below OSHA's 85 dBA action level on modern widebody aircraft, long-haul crew on turboprop and older narrowbody operations face higher exposures — and career-duration cumulative dose across thousands of flight hours creates meaningful cochlear risk. The CDC estimates 22 million U.S. workers face hazardous occupational noise each year, and flight attendants 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 flight attendants work.
Flight attendants employed by U.S. airlines are subject to FAA crew rest and duty regulations but not to a hearing conservation program equivalent to OSHA 1910.95. OSHA 1910.95 applies to airline employees in general industry roles — not to flight crew during flight operations under FAA jurisdiction. The sub-85 dBA career-duration cochlear risk framework applies directly to long-haul cabin crew on many aircraft types.
Measured Noise Exposure Levels
| Operation | Typical Noise Level | OSHA Max Duration |
|---|---|---|
| Narrowbody cabin (Boeing 737, A320 cruise) | 78–84 dBA | Full flight |
| Widebody cabin (777, A350 cruise) | 74–80 dBA | Full flight |
| Turboprop cabin (regional, ATR/Dash 8) | 86–96 dBA | Full flight |
| Galley area (equipment + engine proximity) | 82–90 dBA | Galley duty periods |
| Boarding / deplaning (jet bridge noise) | 82–90 dBA | Boarding duration |
| PA system announcements (at speaker) | 82–94 dBA | Announcement duration |
| Cabin alarm / evacuation signal | 88–100 dBA | Drill/emergency event |
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

Turboprop Cabin Crew: A Higher-Exposure Sub-Population
Regional flight attendants operating on turboprop aircraft — ATR 42/72, Bombardier Dash 8, Saab 340 — face substantially higher cabin noise levels than mainline jet crew. Turboprop cabins routinely measure 86–96 dBA in the aft cabin near the propeller arc, placing these crew members at or above OSHA's action level for flights of any meaningful duration.
A regional flight attendant completing 4–6 turboprop sectors per day on a commuter network is accumulating noise dose at rates that approach industrial exposure levels — yet airline hearing conservation programs for flight attendants are rare, and audiometric monitoring of turboprop cabin crew is essentially nonexistent in most carriers.
The flight attendant who has flown 3,000 turboprop hours in an ATR 72 aft cabin over a 10-year regional career has accumulated occupational noise dose equivalent to years of sub-85 dBA general industry exposure — entirely undocumented and unmonitored.

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 flight attendants 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.
