Provided is a method of correcting temperature characteristics of an audio device that includes a first microphone and a second microphone, including: measuring a temperature of the first microphone at a step (a-1); correcting an output signal of the first microphone at a step (b-1) using the measured temperature at the step (a-1); and calculating an output signal of the audio device at a step (c) using the corrected output signal of the first microphone at the step (b-1).
