Definition
A temporary loss of hearing sensitivity caused by exposure to loud or sustained noise, which gradually recovers after the noise stops. Repeated or prolonged exposure can lead to permanent hearing damage.
Plain English
Your ears get tired and hear less well after being around loud noise for a while. Hearing usually comes back after a quiet period, but doing this often can cause lasting damage.
Context Anchor
Seen in human factors, cockpit noise, headset use, and hearing protection discussions.
Derivation
From Latin 'audire' meaning 'to hear,' and 'fatigue' from French meaning 'weariness.' Together: the ears becoming worn out from listening, just as muscles tire from work.
Why Pilots Care
It can cause pilots to miss or misinterpret ATC instructions, altitude calls, or traffic advisories, raising the risk of communication errors.
Grounding Statement
After a long, noisy flight, if voices and radios seem less clear than usual, auditory fatigue may be part of the reason.
Intuition Check
Auditory fatigue does not mean you are sleepy because of noise. It means your hearing itself has become temporarily less sensitive after noise exposure.
Example Sentence 1
After a long cross-country flight without a noise-cancelling headset, the pilot noticed auditory fatigue and had trouble understanding the tower on the next leg.
Example Sentence 2
Modern noise-canceling headsets reduce auditory fatigue on long cross-country flights so radio calls remain clear.
