Abstract(s)
Ao longo desta dissertação é apresentada a legislação em vigor em Portugal relacionada com a acústica de edifícios, bem como as normas europeias existentes.
Como caso de estudo optou-se por analisar um edifício recuperado no âmbito do programa de reabilitação urbana do Porto, incidindo o estudo experimental na realização de ensaios acústicos, avaliando e validando através dos mesmos as soluções construtivas preconizadas no projeto de execução do edifício. Assim, para cada uma das soluções construtivas, realizaram-se estimativas de acordo com diferentes métodos preconizados nas normas e na bibliografia da especialidade.
Efetuou-se também a avaliação acústica do edifício através do método prescrito pelo Laboratório de Engenharia Civil (LNEC), a qual reverteu numa classificação de acordo com os parâmetros considerados, a qual é apresentada no presente trabalho.
This dissertation lays on the study of acoustics in buildings related legislation currently in force in Portugal, as well as existing European standards. As a case study we chose to analyze a restored building inserted in the Oporto rehabilitation program, focusing the experimental study on the conduction of noise tests, evaluating and validating the constructive solutions adopted in the design of the building. As a method of verifying the results of the tests performed, calculated estimates were made according to different standards and methods recommended in the specialty literature. An acoustic assessment of the building by the method prescribed by the National Civil Engineering Laboratory (LNEC) reverted in a classification, according to the parameters considered, and that is presented in this paper.
