对18名长期接触（6-15年）苯乙烯的工人进行了耳神经学测试，苯乙烯的水平远低于瑞典目前的限值（110 mg/m3）。将结果与参考组的结果进行比较。在7名工人的中枢听觉通路中发现了干扰。16名工人反映不同感觉平衡器官的冲动中枢处理的测试异常。最相关的测试似乎是静态姿势图和旋转视觉抑制测试。在姿势图中，苯乙烯组的摇摆面积明显大于参考组。在视觉抑制测试中，苯乙烯工人表现出明显较差的抑制前庭眼球震颤的能力比参考组。得出的结论是，在工业环境中的苯乙烯暴露在中等或低水平导致中枢神经系统紊乱，这并不总是诊断与心理测试，但可以在特殊的耳神经学测试明显。
An otoneurological test battery was administered to 18 workers with long-term exposure (6-15 years) to styrene at levels well below the current Swedish limit (110 mg/m3). The results were compared with those of a reference group. Disturbances were found in the central auditory pathways of seven workers. Tests reflecting central processing of impulses from different sensory equilibrium organs were abnormal for 16 workers. The most relevant tests seemed to be static posturography and the rotatory visual suppression test. In the posturography the styrene group had a significantly larger sway area than the reference group. In the visual suppression test, the styrene workers displayed a significantly poorer ability to suppress vestibular nystagmus than the reference group. It was concluded that styrene exposure in industrial environments at moderate or low levels causes central nervous system disturbances which are not always diagnosable with psychometric tests but can be apparent in special otoneurological tests.
