| description | This paper reports on the latest results concerning
the active noise control approach using net flow of
acoustic energy. The test set-up consists of two loudspeakers
simulating the engine noise and two smaller loudspeakers
which belong to the active noise system. The system
is completed by two acceleration sensors and one microphone
per loudspeaker. The microphones are located in
the near sound field of the loudspeakers. The control algorithm
including the update equation of the feed-forward
controller is introduced. Numerical simulations are performed
with a comparison to a state of the art method minimising
the radiated sound power. The proposed approach
is experimentally validated. |
