Abstract

The invention relates to the technical field of noise reduction earphones, in particular to an intelligent noise reduction earphone based on an audio decoder and a noise reduction algorithm, comprising a shell, a loudspeaker, a microphone, a noise reduction loudspeaker and a control circuit board which are arranged in the shell; the control circuit board is provided with an audio codec, a wirelessprotocol chip, a noise reduction chip and a noise reduction switch control chip. The switch control chip is used for judging whether to open or close the noise reduction chip according to the environment noise received by the microphone. According to the intelligent noise reduction earphone based on the audio codec, whether active noise reduction is carried out or not can be automatically determined according to environmental noise, and an artificial neural network basic noise reduction algorithm is trained by utilizing an artificial neural network, so that the basic noise reduction algorithmhas robustness for frequency responses of various microphones; and therefore, the noise reduction performance is relatively good in various noise environments.

Description

technical field [0001] The invention relates to the technical field of noise reduction earphones, in particular to an audio decoder-based intelligent voice reduction earphone and a noise reduction algorithm. Background technique [0002] The noise suppression of traditional noise-cancelling headphones is to subtract or partially cancel the noise after knowing the noise model. Existing noise-cancelling earphones are generally provided with a physical noise-cancellation switch, which needs to be turned on or off manually, and cannot be automatically turned on and off according to the rise and fall of environmental noise, which is inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide an intelligent voice-reducing earphone based on an audio decoder and a noise-reduction algorithm to solve the above-mentioned problems. [0004] In order to achieve the above object, a kind of intelligent voice-reducing earphone based on audio ...
