Title Occupational noise exposure and hearing loss in fire fighters assigned to airport fire stations
Bibliographic information Sep. 1991, Vol.52, No.9, p.372-378. Illus. 14 ref.
Abstract Investigators from the National Institute for Occupational Safety and Health (NIOSH) studied hearing levels and noise exposures of 197 fire fighters at 5 metropolitan fire stations. Two of the 5 stations served an international airport. The noise surveys consisted of personal noise dosimetry on fire fighters for the entire 24-hr tour of duty over 2 consecutive days. The audiometric examinations were pure-tone, air conduction tests. The dosimetry results revealed time-weighted averages ranging from 60 to 82dB(A). However, the levels encountered during Code 3 responses (sirens and air horns) reached 109dB(A) for a 1 minute time period. The audiometric results showed that the average fire fighter exhibited a characteristic noise-induced permanent threshold shift. Hearing loss was related to the amount of time on the job with decreasing hearing ability a function of years of service.
