Abstract
Embodiments of the present invention disclose a sensitivity calibration method and an audio device. The method of the present invention includes determining whether a first signal captured in a current frame by a primary capture module is a circuit noise. When the first signal is not a circuit noise, if the first signal has a stationary noise characteristic, a first calibration gain is determined according to the first signal and a second signal captured in the current frame by a secondary capture module. The second signal is calibrated according to the first calibration gain, so that sensitivity of the primary capture module is consistent with sensitivity of the secondary capture module.
