摘要：
A porous acoustic bead resonator is provided, wherein the Young's modulus of the material of the resonator is lower than 1 GPa and the porosity of the resonator is comprised between 20% and 50%, most of the pores of the resonator being filled with a gas and most of the pores being interconnected, via at least one pore, with the exterior of the resonator.
