[Mise en évidence expérimentale de pompage énergétique en acoustique]
Cette Note décrit un montage expérimental destiné à reproduire le phénomène de pompage énergétique entre un milieu acoustique et un oscillateur purement non linéaire. Il montre un transfert irréversible d'énergie entre le premier mode acoustique d'un tube et une membrane visco-élastique mince.
This Note presents an experimental vibro-acoustic set-up that aims to reproduce the energy pumping phenomenon between an acoustic medium and an essentially nonlinear oscillator. It shows a one-way irreversible transfer of energy between the first acoustic mode in a tube and a thin visco-elastic membrane.
