NOISE REDUCTION SYSTEM |
| 摘要 |
Earphone apparatus includes at least one earphone driver operative to receive an input signal and mounted so as to deliver sound to a wearer's ear, and a sensing microphone sensitive to noise around the wearer's head but substantially insensitive to the sound generated by the at least one earphone driver. The earphone apparatus is configured to co-act with an existing remote noise cancellation device, the existing remote noise cancellation device being originally intended for the provision of feedback active control, to enable operation in a feed-forward configuration to effect noise reduction in sound delivered by the at least one earphone driver. |
