ABSTRACT
Introduction:
The study aimed to compare effects of occupational exposure to low frequency noise (LFN) in comparison with those of audible noise (AN).
Material and Methods:
Three groups of 307 workers (I – exposed to LFN, II – exposed to audible noise – AN, and III- controls) were examined.
Results:
Blood pressure and other biochemical parameters were worse in the group exposed. All parameters of hearing were worse in the AN group in comparison with LFN one in whole range of frequency. The same trends were found in posturography.
Conclusions:
The results of the study showed that audible noise is more hazardous than LFN. The results did not support thesis on vibroacoustic disease.
