Abstract

The invention relates to a system for generating anti-noise in an exhaust-gas line (9) of a vehicle, comprising a first electro acoustic transducer (11) configured for generating a first acoustic signal based on an electric control signal, and being in communication with the exhaust-gas line via an acoustic line (4, 7), with the first acoustic signal entering the exhaust line in form of anti-noise after having passed the acoustic line, a second electro acoustic transducer (13) configured for generating an electric measurement signal representing a second acoustic signal, and being in acoustic communication with the exhaust-gas line (9) at the anti-noise coupling region, a control unit (21) configured for generating the control signal based on the measurement signal, and a parameterizing unit (29) adapted for determining a conforming phase parameter and a conforming magnitude parameter for the control function used by the control unit (21) based on the transient response of the control unit.
