PROBLEM TO BE SOLVED: To provide an electroencephalographically induced audio device and method that can induce a desired brain wave state without entailing a feeling of rejection or monotony while listening to music signals or audio signals for learning purposes and without entailing consciousness of any warp of the sound source.SOLUTION: An electroencephalographically induced audio device comprises a frequency transition unit 110 which receives inputting of a first audio source signal 711 and generates a second audio source signal 712 resulting from transition by a prescribed frequency a part of the inputted frequency range, an audio output unit 300 that is connected to the frequency transition unit 110 and delivers a first audio output signal 721 and a second audio output signal 722 respectively matching the first audio source signal 711 and the second audio source signal 712, and a controller 200 that varies at least one of the part of the inputted frequency range and the prescribed frequency according to the user's operation or prescribed setting.SELECTED DRAWING: Figure 3
