As a method for obtaining results that could contribute to the establishment of commercial jet aircraft flight deck noise criteria, fifty persons were exposed to simulations of various flight deck noise exposure conditions. Exposure levels investigated were 75, 80 and 85 dBA for periods of 1, 2, and 4 hours. Noise spectra representing both older narrow-body and newer technology wide-body jet aircraft were utilized. Response measures emphasized were temporary threshold shift (TTS) and speech intelligibility, but annoyance ratings to the exposure conditions were also obtained.
