The present invention relates to an audio device for listening to a radio, a vehicle comprising the audio device, and a method for controlling the audio device. More specifically, the present invention relates to a technology regarding a vehicle comprising an audio device configured to remove a signal in a frequency band including noise of a radio broadcasting signal and to output a broadcasting signal from which the noise has been removed. An audio device according to an embodiment of the present invention comprises: a reception unit which receives a first broadcasting signal corresponding to a frequency selected by a user; a control unit which compares the intensity of a signal in a first frequency band included in the received first broadcasting signal with the intensity of a signal in a second frequency band included in the received first broadcasting signal and determines a frequency band with the higher intensity; and a signal processing unit which generates a second broadcasting signal by shifting a phase of the first broadcasting signal included in the determined frequency band and generates a third broadcasting signal, from which a broadcasting signal in the frequency band corresponding to the higher intensity has been removed, by combining the first broadcasting signal and the second broadcasting signal.
