Apparatus for the active suppression of noise radiated by a surface |
摘要 |
Noise generated by a noise radiating surface is actively suppressed by at least two axially sensitive noise sensors which produce a control signal for controlling a noise suppression actuator. The sensors integrate the sensed signal in an axially selective manner. The at least two sensors are sensing the signal in two directions which preferably cross each other orthogonally. The control signal activates the actuator in such a way that the actuator counteracts deflections or vibrations of the noise generating surface such as a vehicle body wall.
