Abstract
uma estrutura acústica com múltiplos graus de liberdade acústicos para reduzir o barulho gerado a partir de uma fonte. as tampas de septo acústicas, que são uma parte integrante da estrutura acústica, incluem porções de controle de profundidade que podem ser variadas em largura, de modo que as porções de septo de diferentes tampas de septo possam estar localizadas em diferentes profundidades dentro da estrutura acústica para proporcionar uma estrutura acústica com múltiplos graus de liberdade acústica mesmo que as tampas de septo acústicas estejam ancoradas na mesma profundidade dentro da estrutura.
