Problems solved by technology

[0002] At present, active noise reduction usually adopts the method of fixing filter parameters, but because the noise composition is different in different environments, the surrounding noise is eliminated with fixed filter parameters. When the noise of the surrounding environment changes significantly, the noise reduction effect of active noise reduction not stable enough
For example, the peak noise reduction performance of active noise reduction headphones is located at 80-200Hz. When the surrounding environment noise is dominated by snoring at 250-800Hz, the noise reduction experience is not good enough.

Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] At present, most active noise cancellation (Active Noise Cancellation, ANC) headphones are based on a fixed active noise cancellation curve (Active Noise Cancellation Level Curve) by designing fixed active noise reduction parameters to eliminate external environmental noise. The technical principle is as follows: figure 1 As shown, after the microphone collects the external environmental noise, it is processed by the noise reduction circuit through the fixed noise reduction filter parameters, and an anti-phase signal is generated and broadcast through the speaker to offset the external environmental noise. After the fixed noise reduction filter parameters are adop...

Abstract

The invention discloses a noise reduction processing method and device, electronic equipment, an earphone and a storage medium, and relates to the technical field of noise reduction, and the method comprises the steps: obtaining environment sound collected by an audio collection device; inputting the environment sound into a snore detection model to obtain a snore detection result; if the snore detection result indicates that the environment sound contains the snore, determining whether masking sound playing conditions are met or not according to frequency spectrum energy characteristics of the snore; if the masking sound playing condition is met, performing noise reduction processing on the snore, and playing the masking sound. According to the embodiment of the invention, the acquired environment sound is input into the snore detection model to identify the snore, active noise reduction processing is carried out according to the frequency spectrum characteristics of the snore, and when the masking sound playing condition is met, the snore interference is reduced by adopting a masking sound masking mode; compared with snore which is not disturbed by people, comfortable noise such as white noise and sea wave noise is relieved, and the snore noise reduction effect is improved.
