为了研究噪声引起的睡眠障碍，发展了一种新的方法，称为“噪声干扰法”。实验在每个受试者的房子的卧室进行。声音是用一个小型磁盘播放器，具有自动逆转功能。如果声音令人不安且受试者无法入睡，则允许他们在开始尝试入睡后1小时关闭声音。这种关闭（噪音中断行为）是睡眠障碍的重要指标。第二天早上，他们填写了一份问卷，其中询问了睡眠质量，声音干扰，关闭声音的时间等。结果表明，LAeq与一小时内不能入睡的受试者的百分比以及LAeq与问卷中报告的干扰之间存在良好的相关性。这表明，该方法是一个有用的工具，以测量睡眠干扰所造成的噪音在良好的控制条件下。
To study noise-induced sleep disturbance, a new procedure called “noise interrupted method”has been developed. The experiment is conducted in the bedroom of the house of each subject. The sounds are reproduced with a mini-disk player which has an automatic reverse function. If the sound is disturbing and subjects cannot sleep, they are allowed to switch off the sound 1h after they start to try to sleep. This switch off (noise interrupted behavior) is an important index of sleep disturbance. Next morning they fill in a questionnaire in which quality of sleep, disturbance of sounds, the time when they switched off the sound, etc. are asked. The results showed a good relationship between LAeqand the percentages of the subjects who could not sleep in an hour and between LAeqand the disturbance reported in the questionnaire. This suggests that this method is a useful tool to measure the sleep disturbance caused by noise under well-controlled conditions.
