Abstract: PURPOSE: An apparatus for controlling volume and a control method thereof are provided to adjust the volume of an audio signal during an operating mode and a detail mode. CONSTITUTION: First to nth sound source supply units(110-1 to 110-n) output an audio signal. Through an inputted sound source weight, an applicator(140) adjusts the volume of one audio signal of the first to nth sound volume adjustment units(120-1 to 120-n). A sound volume determiner(160) outputs a sound volume control value, and a mixer(170) outputs the outputted audio signal of first to nth sound volume adjustment units as one audio signal. A total sound volume adjustment unit(180) adjusts the volume of the audio signal of the mixer.
