Title
(EN) ADAPTIVE ACOUSTIC CHAMBER AND METHOD FOR ACOUSTIC CALIBRATION
(FR) CHAMBRE ACOUSTIQUE ADAPTATIVE ET PROCÉDÉ POUR ÉTALONNAGE ACOUSTIQUE
Abstract
(EN)
An acoustic chamber comprising: an enclosure that is internally coated with a flexible coating, the flexible coating comprising one or more phono-absorbing materials; an actuator configured to exert pressure on and change the geometry of the flexible coating; and a computerized controller configured to operate the actuator, such that acoustic reflection properties inside the enclosure change as a function of the changing geometry of the flexible coating.
(FR)
La présente invention concerne une chambre acoustique qui comprend : une enceinte qui est revêtue intérieurement d'un revêtement souple, le revêtement souple comprenant un ou plusieurs matériaux phono-absorbants; un actionneur configuré pour exercer une pression sur et modifier la géométrie du revêtement souple; et un dispositif de commande informatisé configuré pour faire fonctionner l'actionneur, de telle sorte que des propriétés de réflexion acoustique à l'intérieur de l'enceinte changent en fonction de la géométrie changeante du revêtement souple.
