The data obtained from these studies suggest that continuous noise at high levels will produce an increase in arousal, as indicated by pupil size, and that there is a tendency toward adaptation. At lower noise levels the effect is, at most, transitory. This papillary change does not appear to mediate a change in visual acuity. Impact noise such as that used here does not appear to produce reproducible changes in pupil size or visual acuity. For the noise conditions used here, concern for nonauditory sensory effects seems to be unwarranted.
从这些研究中获得的数据表明，高强度持续噪声会导致如瞳孔大小所示的觉醒增加，并且存在适应倾向。在较低噪声水平下，这种影响至多是短暂的。这种瞳孔变化似乎并未介导视力的改变。此处使用的冲击噪声似乎不会使瞳孔大小或视力产生可重复的变化。对于此处使用的噪声条件，关注非听觉感官影响似乎是不必要的。
