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.
Physics-inspired Neuroacoustic Computing Based on Tunable Nonlinear Multiple-scattering
Ali Momeni, Xinxin Guo, Herve Lissek +1
Waves, such as light and sound, inherently bounce and mix due to multiple scattering induced by the complex material objects that surround us. This scattering process severely scra…
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…
Robust direct acoustic impedance control using two microphones for mixed feedforward-feedback controller
Maxime Volery, Xinxin Guo, Hervé Lissek
This paper presents an acoustic impedance control architecture for an electroacoustic absorber combining both a feedforward and a feedback microphone-based strategies on a current-…
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…
Joint Estimation of Room Geometry and Modes with Compressed Sensing
Helena Peić Tukuljac, Thach Pham Vu, Hervé Lissek +1
Acoustical behavior of a room for a given position of microphone and sound source is usually described using the room impulse response. If we rely on the standard uniform sampling,…
Localization of Sound Sources in a Room with One Microphone
Helena Peic Tukuljac, Herve Lissek, Pierre Vandergheynst
Estimation of the location of sound sources is usually done using microphone arrays. Such settings provide an environment where we know the difference between the received signals…
