Abstract: a volume adjusting circuit for adjusting gain of a sound signal inputted to thereby adjust the volume of the signal; a converting unit for detecting an output signal of the volume adjusting circuit in a predetermined size and for converting the output signal into a direct current level; and a comparing unit for comparing a level area established by the output level of the converting unit with a noise level detected through a noise detecting unit to generate a gain control signal which controls the gain of the volume adjusting circuit.
