In order to enhance the robustness and the energy range of efficiency oftargeted energy transfer (TET) phenomena in acoustics, we discuss in this paperabout the use of multiple nonlinear membrane absorbers in parallel. We showthis way, mainly thanks to an experimental set-up with two membranes, that thedifferent absorbers have additional effects that extend the efficiency and thepossibilities of observation of TET. More precisely, we present the differentbehavior of the system under sinusoidal forcing and free oscillations,characterizing the phenomena for all input energies. The frequency responsesare also presented, showing successive clipping of the original resonance peakof the system. A model is finally used to generalize these results to more thantwo NES and to simulate the case of several very similar membranes in parallelwhich shows how to extend the existence zone of TET.
