The perceptual classification of emotions, memories, preferences, and wishes is crucial for evaluating the sound quality of sonic environments. Over the years, several psychological taxonomies have developed, aiming to help categorise core emotions. When applied to auditory stimuli, some models simplify emotional dimensions to assess the sound quality of environments. However, aligning emotional taxonomies with psychoacoustic indicators requires careful attention, as individual interpretations can vary widely due to contextual factors such as socio-cultural influences, momentary attention, and the space use and function of the space in question. This study aims to align perceived emotional attributes with psychoacoustic indicators from sonic environments surrounding daycares and playgrounds, utilising data collected through soundwalks, interviews, and listening tests in Brazil, Germany, and the United Kingdom. It will associate emotional classification methods based on the core emotional dimensions proposed by Plutchik [1], Russell [2], and ISO/TS 12913-2 [3]. The psychoacoustical indicators under consideration are loudness, sharpness, roughness, fluctuation strength and tonality. The findings linking core emotions with psychoacoustic parameters for daycare centres and playground areas may identify key sound qualities to consider in these spaces, as well as potential soundscaping design and management strategies.
