Abstract

"PAINEL A PROVA DE SOM". A presente invenção refere-se a um painel à prova de som compreendendo uma parede 'excitadora'para ficar em contato com um fluido no qual há uma fonte de ruido, e uma parede 'receptora' para ficar em contato com um fluido no qual é desejado atenuar o ruído, o painel incluindo entre as mencionadas duas paredes um elemento intermediário (3). O painel é caracterizado pelo fato do elemento intermediário ser mantido sobre pelo menos uma porção de seu contorno por meio de pelo menos um elemento flexível (8) disposto entre a parede intermediária (3) e a parede receptora (2).
