Abstract

Die Erfindung betrifft zunächst ein Verfahren zur Geräuschbeeinflussung in einem Raum (1), wie bspw. einem Großraumbüro, wobei eine aktive Schallunterdrückung und/oder eine Schallmaskierung vorgenommen wird. Um eine aktive Schallunterdrückung bzw. Schallmaskierung in einem größeren Raum, bspw. einem Großraumbüro, vorteilhaft vorzunehmen, wird vorgeschlagen, dass eine Mehrzahl von Schallaktoren (3) über die Fläche des Raumes (1) verteilt vorgesehen werden und in dem Raum (1) weiter mindestens ein Schallsensor (4) angeordnet wird und zwei oder mehr der Schallaktoren (3) im Hinblick auf von dem Schallsensor (4) erfasste Schallwerte und/oder im Hinblick auf eine gewünschte schallmäßige Raumaufteilung und/oder zufolge erfasster Personen- oder Gegenstandssignale, ggf. unterschiedlich, beaufschlagt werden. Gegenstand der Erfindung ist auch ein an einer Decke eines Raumes (1) zu befestigender Schallabsorber (2), bspw. aufweisend ein Schaumstoff-Flächenteil. Um die Effektivität zur Schallunterdrückung oder Schallmaskierung zu verbessern, wird vorgeschlagen, dass der Schallabsorber (2) einen Schallaktuator (3) aufweist.

The invention firstly relates to a method for influencing noise in a room (1), such as, for example, an open-plan office, wherein active sound suppression and / or sound masking is carried out. In order to carry out active sound suppression or sound masking in a larger space, for example an open-plan office, it is proposed that a plurality of sound actuators (3) be distributed over the area of the room (1) and continue in the room (1) at least one sound sensor (4) is arranged and two or more of the sound actuators (3) with respect to sound values detected by the sound sensor (4) and / or with regard to a desired sound distribution and / or according to detected person or object signals, if necessary different, be charged. The invention also provides a sound absorber (2) to be fastened to a ceiling of a room (1), for example comprising a foam surface part. In order to improve the effectiveness for sound suppression or sound masking, it is proposed that the sound absorber (2) has a sound actuator (3).
