Title:
ACTIVE NOISE REDUCTION SYSTEM FOR COMMUNICATION DEVICE AND NOISE REDUCTION PROCESSING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/001930
Kind Code:
A3
Abstract:
Disclosed are an active noise reduction system for a communication device and a noise reduction processing method therefor. An identifiable signal detector is used for detecting an identifiable signal and transmitting the identifiable signal to a signal processor, a noise detector is used for detecting a noise signal at the periphery of a communication device and transmitting the noise signal to the signal processor, the signal processor is used for performing noise elimination processing on the identifiable signal according to the noise signal to obtain a noise-eliminated processed signal, and the signal processor is connected to the identifiable signal detector and the noise detector respectively. The present invention utilizes a noise signal detected to neutralize or cancel the same noise signal which is doped in an identifiable signal, so as to obtain a noise-eliminated processed signal, thereby improving the communication quality of an audio signal and improving the fidelity, definition and identifiability of the audio signal.
