Method and system for selecting sensor locations on a vehicle for active road noise control

An automatic calibration system for determining an arrangement of at least one reference sensor for active road noise control (ARNC) in a vehicle, the system comprising:

• a processing unit;
• a plurality of vibrational sensors mountable on a plurality of structure elements of the vehicle and configured to generate a plurality of vibrational input signals based on vibrations of the plurality of structure elements and to input the plurality of vibrational input signals to the processing unit;
• wherein the plurality of structure elements represent strongest contributions to a transfer of road noise into a cabin of the vehicle;
• and
• at least one microphone mountable inside the cabin of the vehicle and configured to capture at least one acoustic input signal and to input the captured at least one acoustic input signal to the processing unit;
• wherein the processing unit is configured to determine the arrangement of the at least one reference sensor from the plurality of vibrational sensors by determining a subset of vibrational sensors which sense main mechanical inputs of road noise contributing to the at least one acoustic input signal.
