A device for detecting and suppressing noise includes a noise detection device that receives and processes an input signal to determine if the input signal contains noise and provides a detected noise signal indicative of whether or not noise is detected in the input signal. A noise filter receives the input signal and when the detected noise signal does not indicate the presence of noise the noise filter provides an output signal equal to input signal. When the detected noise signal indicates the presence of noise the noise filter processes the input signal through a first filter to provide a filtered signal such that the output signal is equal to the filtered signal. The noise filter comprises a control circuit that receives the input signal and the filtered signal and in response dynamically adjusts a cut-off frequency control signal that controls a cut-off frequency of the first filter.
