80名受试者，40名男性和40名女性，被分配到两组之一，根据他们的自我估计的高或低的敏感性噪音。在实验的第一部分，他们在早上或下午暴露在一系列常见的噪音中。心率和手指脉搏反应进行了测量和记录的敏感性，性别的主题，和一天中的时间。不同类型的噪音进行了比较，这两种反应。心率反应在敏感性组之间存在差异，但在噪音之间没有差异。相反，当使用手指脉冲响应时，敏感性组之间没有显著差异，但在噪声之间观察到明显差异。在实验的第二部分中，从前两个敏感组中选择了10名男性和10名女性受试者。这20名受试者在睡眠期间暴露于与白天相同的噪音中。睡眠时的心率和手指脉搏反应明显大于清醒时，它们对噪音或性别的敏感性没有显著差异。这两个自主反应显示噪声之间的差异，似乎是与他们的噪声等效电平值。与安静的基线夜晚相比。在噪声干扰的夜晚，睡眠模式没有显示出显著的改变，除了瞬时激活相的频率在噪声干扰的夜晚显著增加之外。
Eighty subjects, 40 men and 40 women, were allocated to one of two groups according to their self-estimated high or low sensitivity to noise. In the first part of the experiment, they were exposed to sequences of common noises during the morning or the afternoon. The heart-rate and finger-pulse responses were measured and recorded in relation to sensitivity, sex of subjects, and time of day. The different types of noise were compared for both responses. The heart-rate response showed differences between sensitivity groups but not between noises. In contrast, no significant differences were obtained between sensitivity groups when using the finger-pulse response, but clear differences were observed between noises. In a second part of the experiment, 10 men and 10 women subjects were selected from the previous two sensitivity groups. These 20 subjects were exposed during sleep to the same noises as during the daytime. Heart-rate and finger-pulse responses during sleep were significantly greater than during waking, and they did not differ significantly with respect to sensitivity to noise or gender. These two autonomic responses showed differences between noises that appeared to be related to their noise-equivalent-level value. Compared with the silent baseline night. the sleep pattern showed no significant modification in the night of noise disturbance, except for the frequency of transient activation phases, which was significantly increased in the latter.
