Abstract(s)
A poluição sonora vem aumentando à medida que as cidades crescem, simultaneamente
com a negligência de medidas de isolamento acústico, promovendo problemas de saúde e
ocasionando falta de privacidade para usuários de edifícios. Esse cenário mostra a impor-
tância do desenvolvimento de estudos de desempenho acústico de edificações a partir de
modelos de previsão. O conjunto de normas EN ISO 12354 propõe métodos de cálculo, al-
vos de diversos estudos. Portanto, este trabalho propôs-se a estudar o modelo de previsão
para desempenho acústico de ambientes adjacentes à ruídos aéreos, a partir do método
para materiais homogêneos pesados apresentado na norma EN ISO 12354-1:2017, sendo
o método desenvolvido em um código em Matlab. Os resultados foram comparados com
a previsão da simulação computacional realizada no software AcouBAT, para as mesmas
soluções construtivas. A avaliação foi realizada a partir de três simulações, onde foram
analisadas as diferenças obtidas entre os resultados provenientes do código em Matlab e
do software AcouBAT. Por fim, foi realizada uma análise de quais parâmetros de entrada
tiveram peso maior no resultado final para cada ferramenta.
Noise pollution has been growing as cities grow, simultaneously with the neglect of sound insulation measures, promoting health problems and causing lack of privacy for building users. This scenario shows the importance of developing studies on the acoustic perfor- mance of buildings based on forecast models. The set of EN ISO 12354 standards proposes calculation methods, targets of several studies. Therefore, this work proposed to study the prediction model for the acoustic performance of environments adjacent to airborne noise, based on the method for heavy homogeneous materials presented in the EN ISO 12354-1:2017 standard, the method being developed in a code in Matlab. The results were compared with the prediction of the computational simulation carried out in the Acou- BAT software, for the same constructive solutions. The evaluation was carried out from 3 simulations, where the differences obtained between the results from the Matlab code of the AcouBAT software were analyzed. Finally, an analysis of which input parameters had greater weight in the final result for each tool was carried out.
