Title (EN) SOUND WALL
(FR) MUR DE SON
Abstract:
(EN) The invention relates to a sound wall comprising in total M elements comprising a front face (F), where the sound wall (1) has a lateral extension along an x-axis and a vertical extension along a y-axis, where the sound wall (1) comprises N elements (3), where N sM, which N elements in the front face (F) of each respective of these N elements are provided with a sound radiating unit, such as one or more loudspeaker units, configured to radiate sound energy from the respective front face and into the surroundings, such that a sound field can be created in front of the sound wall; where the sound wall is provided with signal providing. means configured to provide the sound radiating units with a signal that is a combination of input signals, such as the left and right channel signals S j(t), S2(t) of a stereophonic signal. In embodiments of the invention, the sound wall (1) further comprises A elements (2), where A s M-N, which A elements (2) are provided with sound absorbing means associated with the front face (F), whereby the sound wall (1) can be used to reduce the reverberation time of a room or other enclosure, in which the sound wall (1) is provided and/or H elements (4), where H s M-N- A, which H elements (4) comprises hardware components configured to control and provide signals to the sound radiating units in said N elements (3). The invention also relates to a method for controlling a sound field in front of the sound wall.
(FR) L'invention concerne un mur de son comprenant un total de M éléments comprenant une face avant (F). Le mur de son (1) comprend une extension latérale le long d'un axe x et une extension verticale le long d'un axe y. Le mur de son (1) comprend N éléments (3), N≤M, lesquels N éléments dans la face avant (F) de chacun respectif des N éléments comprenant une unité de rayonnement sonore, telle une ou plusieurs unités de haut-parleur, configurée pour rayonner une énergie sonore depuis la face avant respective et aux alentours de telle sorte qu'un champ sonore peut être créé à l'avant du mur de son. Le mur de son comprend des moyens de fourniture de signaux configurés pour fournir aux unités de rayonnement sonore un signal qui est une combinaison de signaux d'entrée, tels que les signaux de canaux gauche et droit Si(t), S2(t) d'un signal stéréophonique. Dans des modes de réalisation de l'invention, le mur de son (1) comprend en outre A éléments (2), A≤M-N, lesquels A éléments (2) comprennent des moyens d'absorption de son associés à la face avant (F). Le mur de son (1 ) peut être utilisée pour réduire le temps de réverbération d'une pièce ou d'une autre enceinte dans laquelle se trouve le mur de son (1) et/ou H éléments(4), H≤M-N-a, lesquels H éléments (4) comprennent des composants matériels configurés pour commander et fournir des signaux aux unités de rayonnement sonore dans lesdits N éléments (3). L'invention concerne également un procédé de commande d'un champ sonore à l'avant d'un mur de son.
