Abstract

A system for attenuating noise in a cabin of a vehicle is provided in which the vehicle has an interior wall (1) defining the cabin and an exterior wall (5) defining a cavity (4) between the interior wall (1) and the exterior wall (5). A plurality of actuators (2) are arranged within the cavity (4), on the interior wall (1) or on the exterior wall (5) for providing a physical actuation resulting in an acoustic disturbance. A plurality of sensors (3) are arranged in the cavity (4) on the interior wall (1), or on the exterior wall (5) to provide indications of acoustic disturbances. A control system uses the indications from the sensors (3) to generate control signals for the actuators (2). In one arrangement the sensors (3) are arranged in an array interspersed between the actuators (2) which are also arranged in an array. A drive signal for each actuator (2) is then generated using the signals from sensors (3) adjacent to the actuators (2).
