  • Patent number: 10029066
    Abstract: Disclosed herein are an audio apparatus and method for inducing a brainwave using a binaural beat, including a frequency shift unit for receiving a first audio sound source signal and generating a second audio sound source signal by shifting some of the frequency band of the first audio sound source signal by a specific frequency, and an audio output unit connected to the frequency shift unit, for outputting first and second audio output signals corresponding to the first and the second audio sound source signals. Accordingly, a user can hear a music signal or an audio signal for learning without being aware of the distortion of a sound source and can change his or her brainwave state without resistance or monotonousness because a required brainwave state is changed by applying a binaural beat to a specific frequency band of an audio signal, in particular, a music signal.
