Human limits in next-generation fighter aviation: psychophysiological stressors, readiness, health, performance, and countermeasures

The transition to fifth- and sixth-generation fighter aircraft is increasing the psychophysiological demands placed on military aircrew. Next-generation fast-jet operations combine sustained and repetitive high-G loading; intermittent hypoxia, hyperoxia, and hypobaria associated with unexplained physiological episodes; prolonged single-seat missions; advanced helmet-mounted displays; acoustic and thermal stress; and...

Discussion

Signed responses from readers of the wire.

✦ Clinical Takeaway ✦

No actionable change for audiologists; this military aviation physiology review has no direct bearing on routine audiology practice.

✦ Why It Matters ✦

While peripheral to audiology, the review highlights noise- and acceleration-induced physiological stressors—including hearing and vestibular risks—relevant to occupational audiologists and researchers working with military populations.

✦ Key Points ✦

01Reviews psychophysiological stressors on aircrew flying 5th- and 6th-generation fighter aircraft.
02Covers health risks including noise exposure, G-force effects, hypoxia, and cognitive load.
03Examines performance factors and readiness in extreme aviation environments.
04Discusses countermeasures to mitigate health and performance degradation.
05Published in Frontiers in Physiology as a broad narrative or scoping review.

Impaired speech-in-noise perception in individuals with a history of hearing symptoms after noise exposure

Audiologists should consider supplementing standard audiograms with speech-in-noise testing for patients reporting noise-exposure symptoms, as normal thresholds alone may miss clinically meaningful hearing dysfunction consistent with cochlear synaptopathy (hidden hearing loss).
