Exploring the Samambaia University Campus soundscape of the Federal University of Goiás: the case studies of the daycare and Student Center

The sound environment plays a critical role in people's mental and physical health. In education, noise pollution decreases learning efficiency and overall well-being. This study is part of a preliminary survey on soundscapes of the Samambaia Campus of the Federal University of Goiás (UFG), in the city of Goiânia, the state capital of Goiás, Brazil. Specifically, the Early Childhood Education Unit (Daycare) and the Central Student Directory (DCE) were analyzed regarding the existing sounds, their impacts on users, and their sound levels. The methodology included sound level readings according to NBR 10.151:2019 and questionnaires on sound quality based on ISO 12913-2:2018, the work of Davies et al. (2013) and emotional states according to Bradley and Lang (1994). The results from the daycare centre indicated that sounds of nature are perceived as pleasant, while mechanical noises are perceived as irritating. On the other hand, in the DCE, people considered human sounds, as both, pleasant and irritating. It is worth noting that this article consists of exploratory data that will guide future research in the area of ??soundscape quality in the Goiânia region.
