Abstract
According to the present disclosure there is provided an active acoustic control system for controlling an acoustic signal propagating along a propagation path, the system comprising: an active control unit configured to: receive information from a first sensor arrangement, the information related to the acoustic signal propagating along the propagation path; generate a control signal for controlling the acoustic signal based on the information from the first sensor arrangement, by being arranged to control: a first control source arrangement comprising a finite 2D array of first control sources for generating a first control signal for controlling a first component of the acoustic signal.

An active acoustic control system for controlling an acoustic signal propagating along a propagation path, the system comprising an active control unit configured to:
- receive information from a sensor arrangement, the information related to the acoustic signal propagating along the propagation path;
- and
- control the acoustic signal based on the information from the sensor arrangement, by being arranged to control a control source arrangement comprising a finite two-dimensional (2D) array of control sources for generating a control signal for controlling a component of the acoustic signal.
A method of controlling an acoustic signal propagating along a propagation path, the method comprising:
- receiving information related to the acoustic signal propagating along the propagation path from a sensor arrangement;
- and
- controlling the acoustic signal based on the received information by controlling a control source arrangement comprising a finite 2D array of control sources for generating a control signal for controlling a component of the acoustic signal.
