Resumo
Este estudo emprega simulação computacional com o objetivo de recriar virtualmente o campo acústico de ambientes internos. Pesquisas que almejam uma modelagem que corresponda de maneira acurada à realidade são indispensáveis para otimizar a análise do comportamento acústico desses espaços, visando à efetivação de um condicionamento acústico eficiente. Com o intuito de auxiliar profissionais no desenvolvimento de projetos de acústica de salas por meio de ferramentas computacionais de código aberto, esta pesquisa explora aspectos cruciais no momento de modelar a acústica de espaços reduzidos, como salas de estúdios de gravação ou home studios. Utilizou-se, neste trabalho, um dos métodos consagrados para simulação computacional desses ambientes, conhecido como Método de Elementos Finitos (MEF), para modelar o campo acústico em uma sala em escala reduzida. O processo envolveu múltiplas fases de ajuste do modelo computacional, fundamentadas em dados experimentais e considerando variáveis como temperatura, umidade, velocidade do som na fonte, difração ao redor de caixas acústicas e características dos materiais absorventes. Os principais resultados destacam o impacto das modificações no modelo, por meio da Função de Resposta em Frequência, da Curva de Decaimento de Energia e do Tempo de Reverberação. Conclui-se que tais informações são importantes para o desenvolvimento da modelagem e de projetos acústicos de salas mais acurados na faixa de frequência de baixa-média densidade modal.
