Abstract
An arrangement with an active noise reduction system for reducing or eliminating disruptive noise in a room (1) having at least one window (9) is disclosed. The arrangement comprises: - a processing unit (20), - at least one sensor unit (21, 22) in the room (1), and - at least one actuator unit (24) in the room (1), the at least one sensor unit (21, 22) and the at least one actuator unit (24) being operatively connected to the processing unit (20). The invention is distinguished in that at least one exterior sensor unit (16) and at least one exterior actuator unit (17) are arranged outside the room (1), both the at least one exterior sensor unit (16) and the at least one exterior actuator unit (17) being operatively connected to the processing unit (20).
