Zusammenfassung:A noise reduction apparatus (and methods). The apparatus has a housing and a processing device coupled to the housing. A sensor is coupled to the processing device and may be adapted to the housing. The sensor is adapted to determine a noise signal. A programmable memory is coupled to the processing device. The programmable memory device comprises 1 to N periodic frequency band limited noise wave shapes that are capable of reducing an intensity level of the noise signal. The apparatus also has an output device that is coupled to the processing device. The output device is adapted to output the periodic frequency band limited noise wave shape that is capable of reducing the intensity level of the noise signal.
