Abstract
The present invention provides an impulsive noise suppression method based on dual-microphone architecture, applied to a hearing aid comprising a first feedforward microphone, a second feedforward microphone, and a speaker, and a sensitivity level of the first feedforward microphone is less than a sensitivity level of the second feedforward microphone, wherein the method comprising: obtaining an input signal comprising a first signal provided through the first microphone and a second signal provided through the second feedforward microphone; determining whether the input signal comprises an impulsive signal according to a first time-domain signal energy value of the first signal and a second time-domain signal energy value of the second signal; and performing an impulsive signal suppression operation on the input signal if the input signal comprises the impulsive signal. The technical scheme provided by the present invention has a simple calculation process, low calculation resource consumption, and fast response speed.
