Apparatus and method for controlling noise in mobile communication terminal

摘要

An apparatus and method for controlling a volume of comfort noise in a mobile communication terminal. The mobile communication terminal includes a vocoder for detecting a decoding rate of voice data received after establishing a voice call to output a detection signal and an amplifier for amplifying an output signal of the vocoder. The method comprises the steps of determining whether the decoding rate of the voice data from the vocoder is 1/8, recognizing the voice data as silence period data containing only the comfort noise and providing the vocoder with a control signal to lower a volume of the comfort noise, if the decoding rate of the voice data is 1/8, and controlling a volume of the voice data such that it becomes a volume preset by a user, if the decoding rate of the voice data is not 1/8.
