Abstract
An apparatus adjusts the frequency characteristic of an audio signal output corresponding to changes in an individual's biorhythms. The apparatus is composed of a key input unit for receiving biorhythm parameters, a ROM for storing a frequency-characteristic adjustment pattern corresponding to a biorhythm change and for selectively outputting the adjustment pattern for each rhythm corresponding to an applied intellectual rhythm, physical rhythm and emotional or sensitivity rhythm as a function of time, a controller for determining the intellectual rhythm, physical rhythm and emotional or sensitivity rhythm for the current day based on parameters input through the key input unit, providing the determination to the ROM and outputting a control signal corresponding to the adjustment pattern output from the ROM, and a frequency-characteristic adjuster for adjusting the frequency characteristic of an audio signal responding to the control signal output from the controller. The apparatus improves aural satisfaction by adjusting the frequency characteristic of an audio signal output according to the user's biorhythm.
