Abstract (en)
Described and claimed is a system for actively reducing noise passing through an opening in a sound barrier, the system comprising sound blocking arrangements. Each sound blocking arrangement comprises a sound source, a sensor and a control circuit. The sensor of each sound blocking arrangement is arranged to sense a sound characteristic in a location in the opening. The control circuit of each sound blocking arrangement is adapted to generate from the signal representative of a sensed sound characteristic a control signal for the sound source of the respective sound blocking arrangement and the sound source of each sound blocking arrangement is adapted to emit sound in accordance with the received control signal. The control signal for each sound blocking arrangement is determined such that the sound characteristic sensed by the sensor of the respective sound blocking arrangement is minimized and the distance between the location in which the sensor of the respective sound blocking arrangement senses a sound characteristic and the sound source of the respective sound blocking arrangement is kept as small as possible.
