Acesso em:.https://repositorio.ufpa.br/handle/2011/7953With the growth of large urban centers in Brazil, the population density and the need for housing led to high demand for semi-detached homes and apartment houses with numerous apartments, however, with the passage of time they became the result of user complaints in consequence of the low performance of the buildings. The normalization of the performance of the buildings was necessary. Several international standards address the issue, but only in 2013 was published the Brazilian standard of buildings performance NBR 15575 (ABNT, 2013), stipulating among other things, requirements for acoustic performance of internal and external walls, and slabs about the noise impact and air. However, there are some questions, such as: does the current construction typology meet these performance acoustic criteria? Are these criteria suitable? Among to answer these questions, field tests and questionnaires were performed with residents. Among the seals whose acoustic performance is required, the results show the inner walls are more distant to meet these criteria, and the external meet with difficulty, even as perceived by users. About the regulatory requirements for acoustic performance, are significant the annoyed levels generated by impact loads on slabs, highlighting the low accuracy, and even more worrying that the latter is the fact in not require acoustic performance criteria regarding the impact noise between walls, highlighted by the vast majority of respondents as the main source of noise.Acesso AbertoEngenharia civilEdifíciosEngenharia acústicaDesempenho das edificaçõesDesempenho acústicoIsolamento acústicoNBR 15575 (ABNT, 2013)Normas técnicas (Engenharia)Civil EngineeringBuildingsAcoustic engineeringBuilding performanceSoundproofingTechnical standards (Engineering)DissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA CIVIL::CONSTRUCAO CIVIL::PROCESSOS CONSTRUTIVOS
