O presente trabalho possui o intuito de analisar o tempo de reverberação dos ambientes internos
dos espaços de restauração do Instituto Politécnico de Bragança – Campus de Santa Apolónia.
A partir de medições in situ foram avaliados os ambientes de restauração comparando aos
parâmetros estabelecidos pela Legislação vigente. A análise dos parâmetros acústicos serviu de
base para a proposição de soluções construtivas que visam a melhora dos ambientes, para que
os níveis de desempenho e conforto acústico sejam atingidos conforme os níveis recomendados.
As avaliações do desempenho das soluções foram elaboradas utilizando o software I-SIMPA,
de código aberto. As análises das simulações dos ambientes com as soluções acústicas
permitiram concluir que os forros em materiais absorventes não apresentaram valores
suficientes para satisfazer a Legislação quanto ao tempo de reverberação. A inserção de painéis
verticais Broadband Compact Absorber (BCA), por sua vez, resultou em valores simulados
condizentes com o exigido, e os parâmetros de definição de fala D50 e índice de decaimento
inicial (EDT) também apresentaram valores satisfatórios com o BCA.
In this work, the reverberation time were analyzed for the internal environments of the Polytechnic Institute of Bragaça’s restaurant. By using in situ measurements, the were evaluated and compared to the parameters established by current legislation. The analysis of the acoustic parameters served as a basis for proposing constructive solutions aimed at improving the environments, so that the levels of acoustic performance and comfort can achieved the recommended levels. The evaluation of the solutions performance was elaborated using the ISIMPA software that has open source. The analysis of the simulations of the environments with the acoustic solutions allowed to conclude that the ceilings in absorbent materials did not present sufficient values to satisfy the standard parameters for reverberation time, on the other hand, the vertical panels Broadband Compact Absorber (BCA) presented values consistent with the required. The parameters of speech definition D50 and index of initial decay also presented satisfactory values with the BCA.
