[Dosimetric evaluation of noise and results of the audiometric examination of a selected group of workers in the refinery-petrochemical industry].
Sonometric and dosimetric measurements of noise at a dozen workplaces of three divisions in a refinery-petrochemical plant have been made. The equivalent level allowable with a view to hearing protection was found to be exceeded by 1-3 dBA at some workplaces. The tonal audiometric test was used to determine threshold levels for 250-8000 Hz frequencies in 122 workers. The present acoustic conditions at the test workplaces do not pose a risk of a significant hearing loss. Only a slight high-frequency hearing loss which might result from noise exposure was diagnosed. Not a single case of occupational hearing impairment conformable with the mandatory diagnostic and certificatory rules was reported.
