Noise exposures in aircraft passenger cabins during flight operations.
NHCA Spectrum 2005 Feb; 22(Suppl 1):25
NIOSH received a request for a noise evaluation from flight attendants working for a commuter airline. The aircraft tested included four turboprop planes and two regional jets. A series of I5-second samples were collected and stored with a real-time analyzer during takeoff, landing, and at cruise altitude. Noise data showed the individual commuter flights were not loud enough to increase the risk of noise-induced hearing loss for flight attendants. However, if the aircraft's noise-vibration suppression system was not operating during flight, then there could possibly be noise overexposures. The spectral data revealed the possibility of interference in communications between passengers and the flight crew. The NIOSH investigator proposed the use of "musiciantype" ear plugs by flight attendants if FAA approval can be obtained.
