Acoustic treatment based on integrated Helmholtz resonators (French)

an acoustic treatment based on Helmholtz resonator is proposed by embedding a resonant structure in a porous material to improve their low frequency behavior such as transmission loss while keeping an acceptable thickness and weight.
