Abstract
A way of reducing undesirable audio signals is provided. A portable device is provided that comprises a sensor to sense an audio signal and a control unit that is communicatively coupled to the sensor. The control unit is provided to receive a first audio signal from a storage unit and to generate a second audio signal based on at least a portion of the sensed audio signal to reduce an undesirable audio signal. The control unit is further provided to combine the first audio signal and the second audio signal and to provide the combined signal through a speaker.
