In Exper. I, 10 normal-hearing college students performed visual acuity, visual search, and pursuit tracking tasks during music presented at 70 or 107 dbA. Only visual acuity was significantly worse during the higher sound level, which suggest that the effect existed at the relatively low level of sensory processing rather than at the level(s) of cognition and decision-making. In Exper. II, 28 similar Ss performed the visual acuity task during either music or noise presented at 70 or 107 dbA. Acuity was impaired by loud music but not by loud noise. It was suggested that the momentary peak levels in music may play a role in disrupting vestibulo-ocular control, and that some workplace noises may partake of this acoustic characteristic.
在实验一中，10名听力正常的大学生在播放70或107分贝A声级的音乐时，进行了视力、视觉搜索和追踪跟踪任务。只有在较高声级时视力明显变差，这表明这种影响存在于相对较低的感觉加工水平，而非认知和决策水平。在实验二中，28名类似的受试者在播放70或107分贝A声级的音乐或噪音时进行了视力任务。大声的音乐损害了视力，但大声的噪音没有。研究表明，音乐中的瞬间峰值水平可能在干扰前庭眼控制方面起作用，并且一些工作场所的噪音可能具有这种声学特性。
