    Abstract: An apparatus for analyzing interference of a wireless communication device includes a frequency detector configured to detect a frequency signal in a low frequency band that is generated in a wireless communication device; and a band-pass filter configured to extract an interference signal reflecting auditory sensitivity at each frequency, in an audible frequency band of the detected frequency signal. Further, the apparatus includes a voltmeter configured to measure a magnitude of the extracted interference signal at each frequency; and an interference determination block configured to determine whether there is an influence of interference of the wireless communication device on an audio device by comparing an interference level of the measured interference signal with a preset interference reference value.
