Abstract

The present invention is applicable to the technical field of intelligent equipment, and provides a method and device for noise reduction of earphones. The method includes: receiving the degree of noise reduction of the earphone set by the user, and the degree of noise reduction refers to the sound before and after noise reduction. The ratio of the sound level; sending the noise reduction degree to the earphone, so that the earphone performs noise reduction processing on the external sound according to the noise reduction degree. The invention enables the user to adjust the noise reduction degree of the earphone through the smart device to change the noise reduction effect when using the earphone, avoiding the need for the user to take off the earphone or suspend audio playback to receive external sounds, and greatly improves the user experience .

Description

technical field [0001] The invention belongs to the technical field of signal processing, in particular to an earphone noise reduction method and device. Background technique [0002] Most of the existing earphones have a better noise reduction effect, which can prevent users from being disturbed by external sounds when enjoying audio. However, the noise reduction effect of the existing earphones is preset before leaving the factory, and the user cannot adjust the noise reduction effect of the earphone according to needs. Contents of the invention [0003] In view of this, embodiments of the present invention provide a method and device for noise reduction of headphones to solve the problem in the prior art that the noise reduction effect of headphones cannot be adjusted according to user needs. [0004] In a first aspect, a method for noise reduction of earphones is provided, the method comprising: [0005] Receive the earphone noise reduction degree set by the user, an...
