[Problems of hearing loss in aviation engineers (professional and ecological aspects)].
Health standards for noise were exceeded 3 times when noise characteristics were measured at jobs and in apartments of engineers engaged in maintenance of modern aircraft. These specialists were exposed to noise in working hours and at night. Audiometry registered hearing problems in 69% of the examinees. 20% of them had hearing loss of the second degree. In engineers living closer to airports hearing was damaged more seriously, especially at frequencies 1000-8000 Hz. This fact demonstrates ecological implication of non-occupational acoustic load. Relevant regression levels were derived from correlation of noise doses with tonal hearing. Natural and experimental investigations proved efficacy of impedancemetry in objective assessment of noise-induced affection of the organ of hearing and hearing restoration in subjects occupationally exposed to noise.
