Verification of emotional taxonomies on soundscape perception responses
Over the last ten years, several researchers investigated the emotional aspect of soundscape perception responses. Some essential findings helped to highlight relevant dimensions of the emotional content of soundscape perceptual responses. Initially, Axelsson et al. (2010) verified the emotional dimensions with the Circumplex model of affect developed by Russell in 1980. Based on their knowledge, they develop an emotional model for soundscape studies containing three dimensions: pleasantness, arousal, and eventfulness. Afterwards, Cain et al. (2013) checked other emotional dimensions with the help of works that described the emotional meaning of sounds, such as calmness and vibrancy. Our work aims to verify other emotional theories and taxonomies to classify cognitive dimensions related to emotions generated by auditory responses to soundscape studies. The Emotion Wheels of Plutchick (1980) and Geneva (2013) are used to classify emotions reported during soundwalks in Aachen, Germany and surveys in Goiania, Brazil. A principal component analysis is helping in the extraction of components that are summarizing the emotional content which is describing the sonic environment. By understanding how the subjects feel about these environments, findings can contribute to optimize how places influence and change the user's emotions which can reflect on improvements of urban sound design.
