A method for changing an audio mode of a broadcasting mobile communication terminal by using a biorhythm is provided to offer the optimum sound to a user by controlling an output sound according to the biorhythm of the user in the broadcasting mobile communication terminal. A biorhythm module receives name and birth date data of a user, and calculates a biorhythm period of the user of a corresponding date(S301-S303). A codec modulates a frequency component of an audio signal according to a biorhythm of the corresponding date. A control unit reproduces the modulated audio signal(S305).
