Abstract

The invention discloses an active noise reduction method and device, a computer readable storage medium and a processor. The method comprises steps that a target audio file is determined, similarity between the waveform of the target audio file and the waveform of a secondary noise signal is larger than a preset threshold value, the secondary noise signal is a noise signal with the propagation direction opposite to that of a primary noise signal in a preset environment, and the primary noise signal is a noise signal at a noise source in the preset environment; and when the target audio file is played by using the audio playing device, the volume of the audio playing device is adjusted based on the current sleep state of the target object in the predetermined environment. The method is advantaged in that a technical problem that a noise reduction mode used in the related technology is reliable and cannot provide good noise reduction experience for a user is solved.

Description

technical field [0001] The present invention relates to the technical field of environmental active noise reduction, in particular to an active noise reduction method and device, a computer-readable storage medium, and a processor. Background technique [0002] Noise has always been a headache for many families. Taking the family as a unit, there may be noises from the outside such as construction and traffic, and there may also be sounds from inside the home such as the operation of various electrical appliances. Sleep requires a noise-free environment. In related technologies, noise reduction mainly adopts active and passive noise reduction methods. The traditional passive noise reduction method can reduce the noise of medium and high frequency noise in a wide frequency range, but the corresponding low-frequency noise suppression effect is not good; the active noise reduction method makes the noise control It is more targeted, can offset the noise, and has a good control e...
