A method of suppressing noise in an input signal having voice components and noise components is provided. The method is an automatic gain control (20) implemented preferably in software. The noise components and the voice components are identified by a noise detection routine (300). The input signal, having an energy level, is provided for amplifying the input signal when the voice components are detected. The input signal is amplified by a gain value proportional to the energy level of the input signal. A bias signal, having an energy level, is provided for amplifying the input signal when the noise components are detected. The input signal is amplified by a gain value proportional to the energy level of the bias signal.
