ACTIVE NOISE CONTROL WITH COMPENSATION FOR ACOUSTIC LEAK IN PERSONAL LISTENING DEVICES |
| 摘要 |
An acoustic noise cancellation (ANC) process is performed during in-the-field use of a personal listening audio device, using a control filter to produce anti-noise by the device. The process includes computing an S_hat filter that estimates a signal path between an earpiece speaker of the device and an error microphone that are at a user's ear. A response associated with the computed S_hat filter is compared to a predetermined response that is stored in the device. The control filter is adjusted in accordance with the comparison. Other embodiments are also described and claimed. |

1. A method for in-the-field use of a personal listening audio device, comprising:
performing an acoustic noise cancellation (ANC) process during in-the-field use of a personal listening audio device using a control filter to produce anti-noise by the device, wherein the process includes computing an S_hat filter that estimates a signal path between an earpiece speaker of the device and an error microphone that are at a user's ear; comparing a response associated with the computed S_hat filter to a predetermined response that is stored in the device; and adjusting the control filter of the ANC process in accordance with the comparison. |
