Abstract
This study examines how combinations of sound sources in green and blue spaces influence emotional responses, thereby elucidating the mechanisms through which these acoustic elements affect mood and contribute to positive soundscape experiences. Seven common sound sources were selected to create 64 audio combinations, using stream sounds as background and incorporating various geophysical sounds (rain drops, wind blowing, tree rustling) and biological sounds (bird songs, frog songs, insect sounds). The listening experiment involved 120 university students who evaluated these soundscape combinations through emotional ratings across three dimensions: pleasure, arousal, and dominance. Data were analyzed using linear mixed models, exploratory data analysis, and piecewise linear regression techniques. The findings revealed that: (1) sound source types significantly affected emotional responses: compositions featuring geophysical sounds substantially enhanced relaxation and calmness, whereas those containing biological sounds markedly increased participants’ arousal and pleasure levels; (2) individuals with varying anxiety levels demonstrated distinct emotional responses to identical audio stimuli: participants with mild anxiety reported significantly higher pleasure ratings compared to other groups, while those without anxiety exhibited reduced tension; (3) as the number of sound sources increased, pleasure gradually diminished, while arousal and dominance levels significantly intensified. Additional analysis identified that the optimal range for eliciting positive emotional experiences such as pleasure, calmness, and relaxation was between 1–5 sound sources, with excessive sound layering diminishing these beneficial effects.
期刊介绍:
Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense.
Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems.
Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
