A NOISE REDUCTION METHOD AND SYSTEM |
摘要 |
Noise reduction methods and systems for reducing unwanted sounds in signals received from an arrangement of microphones are disclosed, the method including the steps of: sensing sound sources distributed around a specified target direction by way of an arrangement of microphones to produce left and right microphone output signals; determining the magnitude or power of the left and right microphone signals; attenuating the signals based on the difference of the magnitudes or powers or values derived from the magnitudes or powers of the left and right microphone signals. |
