The effects of aircraft noise on memory, stress and arousal in older persons

摘要

The aim of the present experiment was to examine memory, stress and arousal in older adults during aircraft noise (66 dBA L_eq) exposure. Since the study replicated the design of Hygge's (1) classroom experiment, a comparison with schoolchildren and the older adults of the degree of impairment in long-term memory recall also could be performed. The subjects, 105 senior citizens 66-74 years of age (62 females and 43 males) took part in three experimental morning sessions. The results showed that aircraft noise impaired long-term memory recall, as well as recognition. With regard to long-term memory recall, aircraft noise effect on older adults was stronger than for the schoolchildren. In short-term memory serial recall decrements were found on earlier items. the subjects reported themselves more stressful, but not more aroused, when exposed to noise.
