1. An integrated circuit for implementing at least a portion of an audio device, comprising:

  • an audio output configured to reproduce audio information by generating an audio output signal for communication to at least one transducer of the audio device;

    a microphone input configured to receive an input signal indicative of ambient sound external to the audio device; and

    a processor configured to implement an impulsive noise detector comprising;

    a plurality of processing blocks for determining a feature vector based on characteristics of the input signal; and

    a neural network for determining based on the feature vector whether an impulsive event comprises a speech event or a noise event.
