Pilot hearing loss: impact on fitness to fly
EASA MED.B.080 framework for pilot hearing loss by class, with audiometry and applied tests
Hearing loss develops with age, occupational exposure or specific pathologies. For pilots the context is special: pressurised cockpit, radio communications, high ambient noise and audio headsets all change the way hearing loss impacts flight safety. This article explains, based on Part-MED MED.B.080 and UK CAA Otorhinolaryngology Guidance Material, what pilot hearing loss actually means and the accepted thresholds.
For the general framework of conditions affecting the medical certificate, read the introductory article. For limitations that may be added to the certificate, including HAL (Hearing Aid Limitation), see the dedicated piece.

Regulatory framework for pilot hearing loss
Regulation (EU) 1178/2011, Part-MED MED.B.080, defines two hearing tests. The first is the conversational speech test at 2 metres with eyes closed, where the AME confirms the pilot can hear normal speech in each ear separately. This is the basic test applicable to all classes. The second is pure-tone audiometry, mandatory for Class 1 applicants and for pilots holding or applying for an Instrument Rating.
The concrete thresholds for pilot hearing loss Class 1 are: max 35 dB at 500, 1000 and 2000 Hz, and max 50 dB at 3000 Hz, in each ear separately. Crossing any of these thresholds triggers a referral to an ENT consultant for a full evaluation.
For Class 2 and LAPL the regulation does not require a routine audiogram, only on suspicion of pilot hearing loss. Suspicion arises from self-reporting, an abnormal conversational test or a known otologic history. UK CAA still recommends a baseline audiogram at initial examination and every 5 years thereafter.
Below-threshold hearing loss: what happens in practice
Pilot hearing loss exceeding 35 dB at one of the 500-2000 Hz frequencies, or 50 dB at 3000 Hz, does not lead to automatic unfit. AMC1 MED.B.080 requires an ENT referral with three objectives: identifying the pathology, assessing the stability of the loss and determining suitability for a hearing aid.
Common pathologies: presbycusis (age-related loss), occupational noise trauma, otosclerosis, chronic otitis media, Meniere’s disease, acoustic neuroma.
Stability: the ENT compares the current audiogram with previous ones. A loss stable over 12-24 months is more favourable than rapid progressive loss.
Hearing aid: allowed for pilots provided it delivers in-cockpit auditory performance (functional test in operational conditions).
Hearing aids and the HAL limitation
EASA explicitly allows the use of hearing aids in flight, provided the effective acoustic performance meets regulatory thresholds. The certificate limitation applied is HAL (Hearing Aid Limitation), requiring the aid to be worn whenever licence privileges are exercised.
In-the-ear aids (CIC, ITC) are the most popular among pilots, due to compatibility with audio headsets.
Behind-the-ear (BTE) aids are accepted, but require an office check for headset integration and absence of acoustic feedback.
Bluetooth / radio streaming aids are accepted, provided they do not interfere with cockpit communications. Some modern aids connect directly to the intercom via telecoil or auxiliary transmitter.
At every renewal, the ENT confirms in the report that the aid remains calibrated and that the pilot meets the speech intelligibility threshold required in the cockpit.
Frequent pathologies driving pilot hearing loss
A few conditions appear often in the pilot population and deserve separate treatment from a certification standpoint.
Presbycusis: bilateral symmetric high-frequency loss, typical after age 50. Slow predictable progression. Certification continues with a hearing aid once thresholds are no longer met without one.
Chronic noise trauma: typical loss centred on 4000 Hz (notched audiogram). Frequent in helicopter and military pilots. Stopping exposure slows progression.
Meniere’s disease: fluctuating loss with vertigo. Incompatible with flying in the acute phase. Recertification after 12 months without vertigo episodes and a favourable ENT report.
Otosclerosis: progressive conductive loss. Surgical treatment (stapedotomy) gives good outcomes. Recertification at 3 months post-op with a favourable audiogram.
Tinnitus: not an automatic unfit. Assessment is based on functional impact and association with objectifiable pilot hearing loss.
Three pathways for pilot hearing loss: monitoring, hearing aid with HAL, temporary unfit
Tinnitus, presbycusis and their operational impact
Tinnitus is common among pilots and is, in itself, compatible with flying. Only situations needing special attention are new-onset tinnitus (which may mask an acoustic neuroma), pulsatile tinnitus (vascular cause) and tinnitus combined with vertigo (Meniere syndrome). In these cases the AME requests full ENT evaluation and brain MRI.
Presbycusis is the main cause of pilot hearing loss in the 50+ age group. The management strategy is simple: yearly audiogram, early intervention with a hearing aid when the regulatory threshold is at risk, regular calibration of the aid. With this approach, most pilots keep their Class 1 certificate up to the age limit.
Frequently asked questions about pilot hearing loss
Does an active noise reduction (ANR) headset help preserve hearing? Yes. A quality ANR headset cuts ambient noise by 20-25 dB, reducing the cumulative career exposure.
Can I fly with an ear infection? No. Acute otitis media compromises cabin pressure regulation and can cause barotrauma. Mandatory grounding until resolution.
How much does a full ENT evaluation with audiogram cost? In Romania, between 300 and 600 RON for consultation + pure-tone audiogram. Speech audiometry and other tests add to the cost.
Does single-ear hearing loss suspend my certificate? Not necessarily. Thresholds apply per ear, so a significant unilateral loss may be compatible if the good ear stays within limits and there is no impact on sound localisation.
Can I use passive in-ear flight earbuds (CEP) instead of an ANR headset? Yes, if they offer equivalent attenuation and adequate speech intelligibility. Many modern models are accepted, but verify integration with the aircraft intercom.
Does progressive pilot hearing loss force me to downgrade to Class 2? Not automatically. With a calibrated hearing aid and HAL on the certificate, many pilots keep Class 1 up to the age limit. The decision is individual and taken jointly with AME and ENT.
Hearing loss prevention across a pilot career
Hearing loss is, to a large extent, preventable. Four operational measures directly affect career duration and the moment the first certificate limitation appears.
Quality ANR headset: investing in an active headset cuts cumulative exposure by 20-25 dB per flight hour. For a pilot flying 800-1000 hours per year, this delays presbycusis by 5-10 years equivalent.
Ground hearing protection: foam plugs such as Etymotic ER-20 or custom-moulded plugs for preflight walk-arounds, run-ups and hangar operations. Under 15 EUR for a reusable pair.
Acoustic breaks: at least 30 minutes of quiet environment between two flight legs. Allows cellular recovery of the inner ear.
Audiologic monitoring: baseline audiogram at hire and comparative audiograms every 12-24 months, regardless of regulatory threshold. Detects loss trends early and enables corrective intervention.
Combined, these four measures significantly reduce the risk that pilot hearing loss will end a career before the Class 1 certificate age limit.
Ear hygiene also matters: avoid inserting cotton buds into the ear canal, manage cerumen correctly (gentle saline irrigation, no high pressure) and book an ENT consultation at the first feeling of blockage. These details help keep the audiogram stable in the long term.
Custom-moulded earplugs for off-duty exposure (concerts, motor racing, shooting ranges) are another layer of protection that many career pilots overlook. The cumulative damage from recreational noise can exceed cockpit exposure over a 30-year career.
Conclusion
Pilot hearing loss is a common condition, especially in the 50+ population or with occupational noise exposure. The EASA MED.B.080 framework offers clear frequency-based thresholds and allows certification with hearing aids through the HAL limitation. The key is regular audiometric monitoring, early intervention with a hearing aid and close cooperation between pilot, AME and aviation-experienced ENT specialist.
