The test set-up consists of so-called primary loudspeakers simulating the noise source and so-called secondary loudspeakers belonging to the active noise system (ANS). The ANS has two accelerometers and one microphone per secondary speaker. The microphone is located in the near sound field of the secondary loudspeaker. One accelerometer is fixed onto the loudspeaker cone. The other accelerometer is attached to the noise source. The control algorithm contains an adaptive feed-forward scheme for the amplitude of the control signal and an approach to compensate phase deviations. The ANS is tested in a configuration with two primary and two secondary loudspeakers.
