10. An active noise cancellation (ANC) system, comprising:
an input to receive an input audio signal of a transient noise as measured by a microphone;
a dynamic range compression (DRC) module to perform DRC on the input audio signal to generate a compressed dynamic range audio signal; and
an ANC module to perform ANC on the compressed dynamic range audio signal to generate a cancellation signal associated with the input audio signal.
