This paper will present a theoretical and an experimental work which deals with the phenomena relating to the interaction of an acoustic wave with an interface between a porous media and a fluid. It is well kown that two different longitudinal waves can propagate through a porous medium, the reflection, transmission and mode conversion in an interface of this kind will be studied in detail. The influence of the impedance of the porous media components on the generation of each mode will be analized and compared with the experimental results.
