Emotional response to natural and artificial sound and indoor sound scape in residential space

Abstract

The demand for effective ways to alleviate stress caused by residential noise is growing. To better understand individual preferences and strategies for reducing noise-induced stress, a laboratory experiment was conducted to classify emotional responses to natural and artificial sounds according to individual characteristics. The survey consisted of two sessions conducted after collecting individual characteristics from participants. Session 1 evaluated preference for sound sources and emotional responses to sound presented from headphone and woofer by using the self-assessment manikin (SAM). Session 2 utilized to assess indoor soundscape. The results showed that both valence and arousal were highly correlated with sound preference, with higher valence and lower arousal tending to be more preferred. In the case of indoor soundscape assessment, water sounds showed significant differences between PC1 and PC2 on the comfortable-annoying axis and the intrusive-uncontrolled axis.
