Active Su-Schrieffer-Heeger-like System
Mathieu Padlewski, Maxime Volery, Romain Fleury +2
An acoustic dimer composed of two electronically controlled electro-acoustic resonators is presented in view of exploring one-dimensional topological phenomena.
Ultrabroadband sound control with deep-subwavelength plasmacoustic metalayers
Stanislav Sergeev, Hervé Lissek, Romain Fleury
Controlling audible sound requires inherently broadband and subwavelength acoustic solutions, which are to date, crucially missing. This includes current noise absorption methods,…
Corona Discharge Actuator as an Active Sound Absorber Under Normal and Oblique Incidence
Stanislav Sergeev, Thomas Humbert, Hervé Lissek +1
In the majority of active sound absorbing systems, a conventional electrodynamic loudspeaker is used as a controlled source. However, particular situations may require an actuator…
PID-like active control strategy for electroacoustic resonators to design tunable single-degree-of-freedom sound absorbers
Xinxin Guo, Maxime Volery, Hervé Lissek
Sound absorption at low frequencies still remains a challenge in both scientific research and engineering practice. Natural porous materials are ineffective in this frequency range…
Improving sound absorption through nonlinear active electroacoustic resonators
Xinxin Guo, Romain Fleury, Hervé Lissek
Absorbing airborne noise at frequencies below 300 Hz is a particularly vexing problem due to the absence of natural sound absorbing materials at these frequencies. The prevailing s…
Constant-pressure sound waves in non-Hermitian disordered media
Etienne Rivet, Andre Brandstötter, Konstantinos G. Makris +3
When waves impinge on a disordered material they are back-scattered and form a highly complex interference pattern. Suppressing any such distortions in the free propagation of a wa…
