Embodiment 1
[0024] figure 1 It is an implementation flowchart of the noise reduction method for controlling earphones provided by the embodiment of the present invention, and is described in detail as follows:
[0025] In step S101, using the terminal microphone to collect the noise signal of the environment;
Embodiment approach
[0026] Among them, using the terminal microphone to collect the noise signal of the environment, there are three implementation methods, which are described in detail as follows:
[0027] The first implementation mode:
[0028] Every preset detection interval, the terminal microphone is used to collect the noise signal of the environment.
[0029] It should be noted that since the environmental noise signal usually does not change much within a period of time, the detection of the environmental noise signal every preset detection interval can further save the power consumption of the terminal .
[0030] The second implementation mode:
[0031] When the distance from the geographic location where the noise signal of the environment was collected last time is not less than the preset distance, the noise signal of the environment is collected by using the terminal microphone.
[0032] It should be noted that since the distance from the geographical location where the noise sig...
Embodiment 2
[0051] This embodiment describes the implementation process of configuring the noise signal processing model, which is described in detail as follows:
[0052] Use the pre-configured noise signal processing model to process the collected noise signal, before generating the judgment result, including:
[0053] Configuring a noise signal processing model, the noise signal processing model includes at least one of a decibel processing model and a signal-to-noise ratio processing model;
[0054] Wherein, the decibel processing model is:
[0055] dB value ≥ τ dB value τ ,
[0056] The dB value is the decibel of the noise signal, and the τ is the preset decibel threshold for openin...
