摘要： An active noise control system for exhaust systems of a combustion engine operated vehicle comprises an anti-sound control connectable to an engine control of the vehicle and a loudspeaker connected to the control for receiving control signals and designed for generating an anti-sound in a sound generator, fluidically connectable to the exhaust system. In the control, at least two curves are stored in order to cancel airborne sound conducted in the exhaust system through outputting the signal to the loudspeaker. The curves cover different temperature ranges of the exhaust gas, which temperature ranges overlap one another by pairs or directly adjoin one another. The control is furthermore designed to select a curve suitable for a respective temperature of the exhaust gas conducted in the exhaust system from the available curves by means of signals output by the engine control and output signals to the loudspeaker making use of this curve.

摘要： Based on sound measured in the interior of an exhaust system components of an ideal control signal are calculated, the components comprising sine wave oscillations comprising amplitudes phase-shifted by 90° relative to each other. From the amplitudes, an overall amplitude is calculated. If the overall amplitude is greater than a reference amplitude, calculating a correction factor from the reference amplitude and the overall amplitude, weighting the amplitudes with the correction factor to obtain weighted amplitudes, and forming the sum of the products of the weighted amplitudes with the associated sine wave oscillations and outputting the sum as control signal to a loudspeaker, follows. Otherwise, if the overall amplitude is smaller or equal to the reference amplitude, forming the sum of the products of the amplitudes of the ideal control signal with the associated sine wave oscillations and outputting the sum as control signal to the loudspeaker, follows.
