Acoustics at an interface : promoting the Lagrange picture

Résumé

In Fluid Mechanics, the Euler description is widely taught and used at the undergraduate level, and the Lagrange description is rather presented as an alternative peculiarity. In this paper, it is argued that, as far as acoustics is envisaged, the Lagrange description occurs to offer a more suitable approach as well from a pedagogical viewpoint as from a technical one. Sound generation by a pulsating source and reflection/transmission at an interface are discussed in this respect.
