| Abstract |
The effects of aircraft noise on the hearing and the auditory pathway function of 112 airport employees were studied. Audiometry and brainstem auditory evoked potentials (BAEPs) were used to evaluate cochlear function and to verify the possibility of retrocochlear involvement. The typical audiogramme pattern of noise-induced hearing loss (NIHL) was a dip at 3 or 4kHz and moderate hearing loss in the frequency range of 6 to 8kHz. Audiogramme results revealed that the prevalence rate of high-frequency loss in all employees was 41.9%. Incidence of NIHL was highest in maintenance workers (65.2%) and firemen (55.0%). For BAEPs, both click threshold and latencies showed that the impairment was most severe in maintenance workers and firemen. The degree of auditory damage coincided with job patterns. Furthermore, damage of both peripheral cochlear organs and the central auditory pathway by high-frequency aircraft noise exposure was confirmed. |
