Patent number: 8930071Abstract: 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.Type: GrantFiled: July 3, 2012Date of Patent: January 6, 2015Assignee: Eberspaecher Exhaust Technology GmbH & Co.
