Abstract

resumo “guia de onda sonora para uso em estruturas acústicas” a largura de banda ou faixa acústica de uma estrutura acústica é aumenta-da localizando um guia de onda sonora (30) dentro da célula acústica (22). o guia de onda divide a célula em duas câmaras acústicas (42, 44). as duas câmaras for-necem um aumento efetivo em comprimento de ressonador da célula.
