Denoising method and equipment

The invention provides a denoising method and denoising equipment. A first sound pressure of audio data received by the first audio input equipment and a second sound pressure of audio data received by the second audio input equipment are acquired, so that the audio data can be subjected to denoising according to difference of the first sound pressure and the second sound pressure and a preset sound pressure threshold value, and the problem that in the prior art, due to the change of distance between a signal source which corresponds to a sound signal and two microphones, a speech signal is suppressed to the same degree as a noise signal can be solved; and therefore, the quality of sound subjected to denoising and the reliability of noise reduction are improved.
