1. A method of processing an audio signal in a terminal device, the method comprising:
acquiring an audio signal of a frequency domain for a current frame;
dividing a frequency band into a plurality of sections;
acquiring energies of a first section and a second section from among the plurality of sections;
determining whether the audio signal of the current frame includes noise based on an energy difference between the first section and the second section; and
applying a suppression gain to the audio signal of the current frame and outputting the audio signal of the current frame applied the suppression gain, based on a result of determining,
wherein the first section and the second section are non-overlapped in the frequency band, and
wherein at least one of the first section and the second section is determined as a shock noise section based on the energy difference.
