Active control of electroacoustic resonators in the audible regime: control strategies and airborne applications
Matthieu Malléjac, Maxime Volery, Hervé Lissek, Romain Fleury
Abstract
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 techniques, particularly for low-frequency. We review the main control techniques related with airborne acoustic wave in the audible regime, emphasizing electrodynamic loudspeakers and piezo-diaphragms, and their applications. We conclude by discussing perspectives in this evolving field.
