DETECTION OF ACOUSTIC IMPULSE EVENTS IN VOICE APPLICATIONS

In accordance with embodiments of the present disclosure, an integrated circuit for implementing at least a portion of an audio device may include 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. The impulsive noise detector may include a sudden onset detector for predicting an occurrence of a signal burst event of the input signal and an impulsive detector for determining whether the signal burst event comprises a speech event or a noise event.
