According to the present invention, an earphone apparatus capable of outputting sound source optimized about hearing character of an individual is provided, which comprises: a hearing character information setting unit which set up and stored in hearing character of an individual after processing by providing the hearing character data which is corresponding to a sound pressure level in which an audio in each frequency from hearing character information collecting device is optimized; a sound source character information generation unit to generate the sound source character information after processing by detecting the sound pressure level in each frequency when providing the sound source from the sound source providing unit; a sound pressure level adjusting unit to generate the sound level adjust information by adjusting the sound level so as to correspond the audio in each frequency to the optimized sound pressure level in which audio level in each frequency included in the sound source character information is included in the hearing character information after comparing the sound source character information with the hearing character information; an equalizing unit to perform an equalizing process for the sound pressure level based on the sound pressure adjust information; a sound output unit to output the equalizing processed sound source through the speakers. |
