A sound masking system according to the invention is disclosed in which one or more sound masking loudspeaker assemblies (410) are coupled to one or more electronic sound masking signal generators (410). The loudspeaker assemblies (410) in the system of the invention have a low directivity index and preferably emit an acoustic sound masking signal that has a sound masking spectrum specifically designed to provide superior sound masking in an open plan office. Each of the plurality of loudspeaker assemblies (410) is oriented to provide the acoustic sound masking signal in a direct path into the predetermined area in which masking sound is needed. In addition, the sound masking system of the invention can include a remote control function by which a user can select from a plurality of stored sets of information for providing from a recipient loudspeaker assembly an acoustic sound masking signal having a selected sound masking spectrum.
L'invention concerne un système de masquage sonore dans lequel un ou plusieurs ensembles haut-parleur (410) de masquage sonore sont couplés à un ou plusieurs générateurs (401) de signal de masquage sonore électronique. Les ensembles haut-parleur (410) du système de signal de masquage sonore acoustique présentent un spectre de masquage sonore. Chaque ensemble haut-parleur (410) est orienté de manière à fournir un signal de masquage sonore acoustique dans un trajet direct dans la zone prédéterminée nécessitant un masquage sonore. Par ailleurs, le système de masquage sonore peut comporter une fonction de commande à distance au moyen de laquelle un utilisateur peut sélectionner à partir d'une pluralité de groupes mémorisés d'informations un élément afin d'alimenter l'ensemble haut-parleur destinataire et un signal de masquage sonore acoustique ayant un spectre sélectionné de masquage sonore.
