A Preliminary Study on the Elderly's Perception of High-Frequency Sound Sources and Soundscape Evaluation
In view of the growing aging trend in China and the large number of elderly people with hearing loss,we focus on the perception and soundscape evaluation of high-frequency sound sources by elderly people.Taking Jiefang Park in Wuhan City as the study area and the elderly and youth groups as the study subjects,relevant data were collected and statistically analyzed through field experiments and questionnaires.The results indicate that there are significant differences in the perception of high-frequency sound sources between the elderly and the young.The elderly group exhibits a notable lack of perception towards high-frequency sound sources.By increasing the loudness of natural high-frequency sound sources such as birdsong and cicada chirping,the perception and evaluation of soundscapes among the elderly can be improved.Additionally,the elderly have a relatively higher demand for the loudness of birdsong and cicada chirping.The findings can provide valuable references for barrier-free design of soundscapes in outdoor environments such as parks,nursing homes,and residential areas.
