Mean audiometric profiles of IAF pilots, followed along over two decades of active military flight, indicate hearing threshold shifts in the high frequencies range, compatible with noise damage. Slight shifts at 4 kHz were first noted in mean audiograms of 30-year-old pilots, suggesting noise effect rather than age-induced hearing loss. However, no flight variable such as flying platform or hours of flight was associated with deterioration of hearing thresholds, and no significant difference from non-flying controls (ATCs) was seen.
