Abstract:
A system for cancelling objectionable wind noise in a vehicle cabin includes a wind noise identification module that is configured to receive data from a microphone indicating a noise measured in a cabin of a vehicle and determine whether the noise is objectionable wind noise based on (i) a position of a moveable panel configured to cover an opening in a body of the vehicle and (ii) at least one of an amplitude of the noise and a frequency of the noise. The system also includes a first noise cancellation module that is configured to generate a noise cancellation waveform to mitigate the noise based on at least one of the amplitude of the noise and the frequency of the noise when the noise is objectionable wind noise.
