Abstract:
The present disclosure is directed to a system and a method for spectral shaping of vehicle noise cancellation. In an example implementation, the method includes determining a center frequency of an expected tonal peak within a selected noise band based upon vehicle data, generating a noise cancellation signal using a weighted shaping filter to shape the noise band, and outputting the noise cancellation signal to smooth the expected tonal peak.
