Abstract

Sinop city has about 143,000 inhabitants and is located in the north of Mato Grosso in the Legal Amazon region. The city has large green areas and some of them are suffering alterations in the soundscape through urbanization, such as the Aquarela do Brasil neighborhood, Parque Florestal, and Tarumãs Avenue. The soundscapes in these three locations were defined as objects of study because they have different typologies and uses, two of them wooded and another with little vegetation located in the center of the city. The objective of the research is to identify the preservation points of the soundscape and to define which of them interfere in the feeling of comfort of people from a subjective analysis. Questionnaires were answered by users to understand the soundscapes and the relation of comfort within the environment they have with the identification of different sounds of the soundscape. The subjective results involve physical, sensitive, and psychological variables, which are presented and claimed in this article. It was verified that the existing sound levels in the analyzed locations are above the limit imposed by the Brazilian regulation, however, there is a satisfaction of comfort defined by most users of these urban spaces.
