 The present study aimed to compare the physiological responses and subjective assessments caused by environmental stimuli between young adults and the elderly. Research was conducted using a quasi-experimental design with 30 young adults [mean age 23.2 years, standard deviation (SD) = 4.6] and 30 community-dwelling elderly people (mean age 74.6 years old, SD = 5.7). Data were obtained regarding heart rate variability, skin potential response (SPR), comfort level, and other subjective assessments, following six types of auditory stimuli of specific situations. These included exercising to music, conversations taking place in multiple locations in a common room, white noise, etc. Compared with changes in the non-stimulus, SPR significantly increased with common room conversation (p <0.01) and white noise (p <0.01) for the young adult group, and with ball games/recreation (p <0.01) and traffic/ambulance (p <0.01) for the elderly group. Several characteristics of the response to sounds were clarified for the elderly, including sounds that are more likely to be assessed as comfortable and those that are easier to recall. In addition, the elderly and young adults differed not only in autonomic nervous indicators but also in subjective assessments. While providing environmental care, nurses need to make appropriate judgments that are not overly subjective. Analysis of covariance on each auditory stimulus, with age as a covariate, showed that LF/HF in the hearing impairment group was significantly higher than that of the non-hearing impairment group for common room conversation (p <0.01), etc.
