Investigation of long acoustic waveguides for the very low frequency characterization of monolayer and stratified air-saturated poroelastic materials
Erick Ogam, Zine El Abiddine Fellah, Géry Ogam, Nicholas O Ongwen, Andrew O Oduor (Elsevier, 2021)When sound propagates in a porous medium, it is attenuated via several energy loss mechanisms which are switched on or off as the excitation frequency varies. The classical way of measuring acoustic energy loss in porous ...
