The present invention relates to a noise reduction module, one or more microphones; The noise analysis unit for converting the analog voltage that is input from the microphone into digital data by a predetermined threshold value or more only noise in the audio frequency band from the noise generated from the motor analysis and learning; Reverse phase signal generation section in response to the noise analysis result inputted from the noise analysis unit generates the anti-phase noise signal for the reference value or more noise within the audio frequency band; Reverse phase noise generation section to convert the anti-phase signal received from the anti-phase signal generation unit into an analog signal and amplification; A memory unit for the noise of other non-frequency characteristic of the pre-learned noise in the audio frequency band storing the noise learning list is updated each time detected by the noise analyzing unit; And having at least one speaker for outputting the analog signals received from the anti-phase noise generation section.
