| description | Disclosed is a sound-processing apparatus and a sound-processing method. The sound-processing apparatus comprises at least one pair of sound transducers, each pair of which comprises a first sound transducer for receiving an audio source signal and outputting a first sound signal according to the audio source signal and a second sound transducer for receiving the audio source signal and outputting a second sound signal according to the audio source signal, the second sound signal having opposite phase from the first sound signal and difference between an amplitude of the second sound signal and an amplitude of the first sound signal being less than or equal to an amplitude threshold value; and a sound acquisition device for acquiring a sound signal, path-characteristic difference between an amplitude-frequency characteristic of a first sound path from the first sound transducer to the sound acquisition device and an amplitude-frequency characteristic of a second sound path from the second sound transducer to the sound acquisition device is less than or equal to a first characteristic threshold value. In this way, a good effect on physical noise reduction can be achieved. |
