Active control of electroacoustic resonators in the audible regime: control strategies and airborne applications

Romain Christophe Rémy Fleury, Hervé Lissek, Maxime Volery, Matthieu Francis Malléjac

Passive sound mitigation techniques have garnered attention whether for absorption, isolation, reverberation or new wave phenomena observation. In parallel, a wide range of research has been devoted to active control strategies, which complement passive te ...

Experimental assessment of a programmable Electroacoustic Liner in a representative turbofan facility

Hervé Lissek, Maxime Volery

The Flightpath 2050 European Union stringent regulations for aviation noise reduction, along with the new generation of Ultra-High-Bypass-Ratio turbofans to reduce fuel consumption, significantly challenge the scientific community to find unprecedented aco ...

Observation of amplitude-driven nonreciprocity for energy guiding

Romain Christophe Rémy Fleury, Hervé Lissek, Mathieu François Padlewski

The non-Hermitian skin effect is an intriguing physical phenomenon, in which all eigenmodes of a non-Hermitian lattice become localized at boundary regions. While such an exotic behavior has been demonstrated in various physical platforms, most realization ...

Practical realization of chiral nonlinearity for strong topological protection

Romain Christophe Rémy Fleury, Hervé Lissek, Mathieu François Padlewski, Xinxin Guo

Nonlinear topology has been much less inquired compared to its linear counterpart. Existing advances have focused on nonlinearities of limited magnitudes and fairly homogeneous types. As such, the realizations have rarely been concerned with the requiremen ...

The Advection Boundary Law in presence of mean flow and plane wave excitation: Passivity, nonreciprocity and enhanced noise transmission attenuation

Hervé Lissek, Maxime Volery

This paper follows a previous publication, where the so-called Advection Boundary Law lining an acoustic waveguide, in absence of mean flow, was studied in terms of its potentials for noise isolation and non-reciprocal propagation. The Advection Boundary L ...

Smart Acoustic Lining for UHBR Technologies Engine Part 2: acoustic treatment at the intake of a scaled turbofan nacelle

Hervé Lissek, Maxime Volery

The new generation of Ultra-High-By-Pass-Ratio (UHBR) turbofan engine while considerably reducing fuel consumption, threatens higher noise levels at low frequencies because of its larger diameter, lower number of blades and rotational speed. This is accomp ...

Initial Conditions Impact on Nonlinear Dynamics of a Loudspeaker

Hervé Lissek, Xinxin Guo

In contrast with linear systems, forced oscillations at particular frequencies may result in more than one stable limit cycle in the dynamic response of a nonlinear system. Also known as jump phenomenon, in these frequency regions, a nonlinear system would ...

Energy harvesting and inter-floor impact noise control using an optimally tuned hybrid damping system

Hervé Lissek

Impact-loaded floor structures radiate undesired sound waves into adjacent rooms, compromising the acoustic comfort. On the other hand, substantial structural vibrations caused by the impact loading offer a promising energy source for harvesting. Neverthel ...

Ultrabroadband sound control of 3D spaces using plasmacoustic metalayers

Hervé Lissek, Stanislav Sergeev

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 ...

Corona-discharge acoustic transducer as a perfect matched acoustic source

Hervé Lissek

A reliable sound source is essential in acoustic facilities, such as impedance tubes. However, conventional loudspeakers, regardless of their design, are prone to sound reflections, contrarily to theoretical matched sources. This can severely compromise th ...
