Abstract : The study investigated the effects of noise on sleep and post-sleep behavior in two 25, 50, and 70 year-old males. The subjects were run for 15 consecutive nights, the first five and the fifteenth serving as controls. Following each night's sleep, subjects completed a series of performance and psychological tests. Threshold sound levels for sleep disturbance were obtained for an impulse and a continuous test noise and discussed in terms of type of sleep disturbance stage of sleep, time of night, adaptation, and age of subjects. The sleep profile results indicated that the pattern of noise-induced sleep disruption was related to age. The 25-year olds showed an increase in stage 1 and movement time. The 70-year olds showed an increase in time awake and a decrease in time spent in stage 3-4. The 50-year old subjects were intermediate with respect to each measure. The daytime performance data revealed no effects of noise-induced sleep disruption on pursuit rotor and reaction time tasks but some decrements were found in time estimation, arithmetic, and memory task measures. In addition, verbal sample scores demonstrated an increase in cognitive impairment and a decrease in human relations. (Author)
