TEMPORARY INDEXES OF LONG LATENCY AUDITORY EVOKED POTENTIALS IN WORKERS WITH SHORT LENGTH OF SERVICE IN NOISE

Shidlovskaya T.A., Shevcova T. V. (Kiev)

Summary

Temporary indexes of components of long latency auditory evoked potentials (LLAEP) in 64 workers of "noisy" professions of machine works with age from 21 to 42 years and length of service from 1 to 10 ones. It were established that even in initial stages of development of professional sensorineural hearing loss in noisy conditions, the cortical depatr-ment of acoustic analyzer is damaged. That is testified by reliable elongation of latent period of N2 LLAEP component at ipsilateral stimulation by tones of 1 and 4 kHz. This fact has be noted at planing and introducing into practice of prophylaxy and treatment for prevention of development of professional sensorineural hearing loss and its progressing in personal of "noisy" machine-building works.
