Abstract: An apparatus for detecting unwanted noise includes a reference sensor that generates a reference signal in response to stimulation by a source. A combined noise detector picks up a combined noise signal, which includes both background noise and the unwanted noise generated by the source. A noise separation synthesis device filters both signals to generate a coherent unwanted noise signal from the combined noise signal as a function of the reference signal generated by the reference sensor. A comparator determines the presence of unwanted noise by calculating the Kurtosis value of the coherent unwanted noise signal.
