The social distancing caused by COVID-19 has caused changes in the dynamics of cities around the world. Measures to restrict the use of public and collective spaces caused, by reducing circulation, work and leisure, a reduction in the sound pressure levels (NPS) of environmental noise. In the face of social isolation, the needs of people in cities for new challenges in the context of buildings, the urban and noise environment were observed. In order to investigate the sound perception of the inhabited space, an online questionnaire was prepared entitled �Survey of the sound perception of the inhabited space in the face of the COVID-19 pandemic�, which began on May 7, 2020. The link to access the form is https://forms.gle/ABxiW193pHWoRQUeA. This research seeks to understand the perception of individuals in relation to their living environment and the outdoor spaces of their location (neighborhood, city), in order to debate possible post-pandemic changes. It is expected that the questionnaire will make it possible to analyze and compare different contexts in Brazil. It is estimated to reach a sample of 1,500 voluntary participants. The results will be reproduced through graphs, tables and maps, being published in indexed scientific journals, and observing aspects relevant to a reflection on the topic of the population's acoustic comfort when facing future habitability behaviors in the face of viral pandemics. Therefore, the research will bring benefits to the community, as it seeks to contribute to greater knowledge of the population's spatial needs, with an emphasis on noise pollution and the acoustic comfort of its inhabitants.
