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