With an acoustic device according to an embodiment, an acquiring unit acquires a frequency characteristic of external noise caused by road noise or the like and a converting unit converts a frequency characteristic of the acquired external noise to an auditory sensitivity characteristic in accordance with a frequency characteristic of auditory sensitivity. In the acoustic device, a setting unit sets a parameter (401) that is in accordance with an auditory sensitivity characteristic in an equalizer (12). The equalizer corrects, in accordance with the parameter that is set by the setting unit, a frequency characteristic of an audio signal that is played back by a playback unit (10).
