DETECTING AND SWITCHING BETWEEN NOISE REDUCTION MODES IN MULTI-MICROPHONE MOBILE DEVICES |
| 摘要 |
A method of switching between noise reduction modes in multi-microphone mobile devices may include receiving a first sound signal at a first sound receiver and receiving a second sound signal at a second sound receiver. The method may also include determining a first power value associated with the first sound signal and determining a second power value associated with the second sound signal. The method may additionally include comparing the first power value to the second power value and switching between a single-microphone noise reduction mode and a dual-microphone noise reduction mode based on the comparison. |

1. A method of switching between noise reduction modes in multi-microphone mobile devices, the method comprising:
receiving a first sound signal at a first sound receiver; receiving a second sound signal at a second sound receiver; determining a first power value associated with the first sound signal; determining a second power value associated with the second sound signal; comparing the first power value to the second power value; and switching between a single-microphone noise reduction mode and a dual-microphone noise reduction mode based on the comparison. |
