Ultrabroadband sound control of 3D spaces using plasmacoustic metalayers

Controlling sound in three-dimensional spaces is a complex task, challenged by the intricacies of acoustic modal structures, the variety of noise sources, and the propagation of waves. This research analyzes the influence of local impedance control on the ...

Ultrabroadband sound control with deep-subwavelength plasmacoustic metalayers

Hervé Lissek, Romain Christophe Rémy Fleury, Stanislav Sergeev

Controlling audible sound requires inherently broadband and subwavelength acoustic solutions, which are to date, crucially missing. This includes current noise absorption methods, such as porous materials or acoustic resonators, which are typically ineffic ...

Plasma-Based Acoustic Metalayer for Sound Control

Hervé Lissek, Stanislav Sergeev

Control of sound with active metamaterials presents several apparent advantages over passive approaches such as extended bandwidth of control, tunability of the technique, new acoustic properties not achievable with passive materials, and often a more comp ...

Corona discharge actuator as an active sound absorber under normal and oblique incidence

Thomas Humbert, Hervé Lissek, Stanislav Sergeev

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 that is more resistant to harsh environments, adjustable in shape, and light ...

Development of a plasma electroacoustic actuator for active noise control applications

Alan Howling, Pénélope Leyland, Ivo Furno, Hervé Lissek, Gennady Plyushchev, Stanislav Sergeev

Conventional loudspeakers generate sound through the vibration of a diaphragm, attached to a rigid frame through elastic suspensions. Although such construction is satisfactory for sound diffusion in steady environments, it is likely to fail in harsh condi ...
