Chronic exposure to whole body vibration can affect the gastrointestinal system, the lumbar spine, the peripheral veins and the vestibulocochlear system. 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). 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. 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 ( < .05). There was no significant difference between Group 1 and Group 2 in terms of canal deficits ( > 0.05). Semicircular canal deficit can be seen with the synergistic effect of noise and vibration.
长期全身振动暴露会影响胃肠系统、腰椎、外周静脉和前庭蜗系统。本研究的目的是使用视频头脉冲试验（vHIT）评估在有噪声和无噪声环境中振动对前庭系统的影响。本研究共纳入138名员工。第1组暴露于振动和噪声。第2组仅暴露于振动，未暴露于噪声。第3组未暴露于噪声或振动。第1组84名参与者中有41名出现半规管功能减退，第2组24名参与者中有7名，第3组30名参与者中有1名。第1组和第2组的半规管功能减退情况比第3组更多（<0.05）。第1组和第2组在半规管功能减退方面无显著差异（>0.05）。噪声和振动的协同作用会导致半规管功能减退。
