Effect of vibration on the vestibular system in noisy and noise-free environments in heavy industry.

Background: Chronic exposure to whole body vibration can affect the gastrointestinal system, the lumbar spine, the peripheral veins and the vestibulocochlear system. Aims/Objectives: The aim of this study was to evaluate the effects of vibration on the vestibular system in noisy and noise-free environments using the video head impulse test (vHIT). Material and Methods: A total of 138 employees were included in this study. Group 1 were exposed to vibration and noise. Group 2 only exposed to vibration, with no exposure to noise. Group 3 were not exposed to noise or vibration. Results: Canal deficit was observed in 41 of 84 participants in Group 1, 7 of 24 participants in Group 2, and 1 of 30 participants in Group 3. There were more canal deficits in Group 1 and Group 2, than in Group 3 (p < .05). There was no significant difference between Group 1 and Group 2 in terms of canal deficits (p > 0.05). Conclusions and Significance: Semicircular canal deficit can be seen with the synergistic effect of noise and vibration.
