Abstract

The invention provides a denoising method and device. The method comprises the steps of collecting environment noise signals; generating inversion signals of the environment noise signals; and playing the inversion signals, thereby denoising the environment noise signals. Through application of the method and the device, the problem that environment noise is difficult to eliminate is solved, and the environment noise is denoised.

Description

technical field [0001] The present invention relates to the field of noise reduction, in particular to a noise reduction method and device. Background technique [0002] Noise, also called noise, is an unwelcome sound that annoys those who hear it and the natural world. The sound that affects people's work, study and rest is called noise. The perception of noise varies from person to person, so noise is sometimes a subjective perception. Generally speaking, people refer to environmental sounds that affect people's conversation or thinking as noise. [0003] Although the earphone products we use are becoming more and more high-end, and the quality of enjoying music is also getting higher and higher, but we have to admit that the noise pollution in the city is getting more and more serious. If you use ordinary earphones outdoors, you can only increase the volume to cover the noise. If there is too much noise, not only will you not be able to enjoy the wonderful music, but i...
