Electroacoustic resonators: system identification and stability
Hervé Lissek, Sami Driss Karkar, Thomas Laurence, Gaël Matten
An Electroacoustic Resonator consists of a loudspeaker used as a membrane resonator, through anacoustic pressure-based controlled electrical current, in order to vary its vibrating velocity in re-sponse to an exogenous sound field. This way, the loudspeake ...
Canadian Acoustical Association2019Fully symmetrical single-suspension electrodynamic loudspeaker using a Halbach array
Invented at the end of the XIXth century, the electrodynamic loudspeaker has not much changed sincethen. Although the materials have greatly evolved, the geometry and the transduction principle staythe same. In many applications, the presence of two sets o ...
Canadian Acoustical Association2019Toward Wideband Steerable Acoustic Metasurfaces with Arrays of Active Electroacoustic Resonators
Romain Christophe Rémy Fleury, Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Thomas Laurence
We introduce an active concept for achieving acoustic metasurfaces with steerable reflection properties, effective over a wide frequency band. The proposed active acoustic metasurface consists in a surface array of subwavelength loudspeakers diaphragms, ea ...
2018Development of a wideband steerable acoustic metasurface composed of active electroacoustic resonators with COMSOL
Romain Christophe Rémy Fleury, Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Thomas Laurence
The recent introduction of acoustic metamaterials and metasurfaces in the literature has triggered an tremendous interest in the scientific community, with their capability to achieve extraordinary acoustic properties for various acoustic and noise control ...
2018Développement et validation d'une métasurface acoustique orientable large bande composée de résonateurs électroacoustiques actifs
Romain Christophe Rémy Fleury, Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Thomas Laurence
Nous proposons un concept de métasurface acoustique orientables en réflexion, effective sur une large bande de fréquences, à l’aide de cellules actives. La métasurface est composée d’un réseau de haut-parleurs petits devant la longueur d’onde, dont l’impéd ...
2018Conception d'une zone d'écoute personnelle par contrôle d'impédance déporté
Hervé Lissek, Romain Boulandet, Thomas Laurence
Afin de proposer des espaces d’écoute personnels dans des environnements bruyants, il est d’un grand intérêt de pouvoir concevoir une zone de silence, et ce sans appareillage envahissant l’espace de l’utilisateur. Ces travaux proposent une approche de cont ...
2018Design of Remote Quiet Zones Using Spot-Type Sound Reducers
Hervé Lissek, Romain Boulandet, Thomas Laurence
This paper presents a local control approach to generate remote quiet zones. To deal with situations where global control can hardly be achieved, it is proposed to use an arrangement of spot-type sound reducers as originally suggested by Olson and May. Ass ...
