Example Embodiment
[0023] Example one
[0024] figure 1 It is an implementation flowchart of a method for controlling earphone noise reduction provided by an embodiment of the present invention. The details are as follows:
[0025] In step S101, the terminal microphone is used to collect noise signals in the environment;
Example Embodiment
[0026] Among them, using the terminal microphone to collect the noise signal of the environment, there are three implementation methods, which are detailed as follows:
[0027] The first implementation:
[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 noise signal of the environment usually does not change much in a period of time, the detection of the noise signal of the environment 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 terminal microphone is used to collect the noise signal of the environment.
[0032] It should be noted that since the terminal is located at a distance from the geographic location detected by the noise...
Example Embodiment
[0050] Example two
[0051] This embodiment describes the implementation process of configuring the noise signal processing model, which is detailed as follows:
[0052] Use the pre-configured noise signal processing model to process the collected noise signal, and before generating the judgment result, including:
[0053] Configuring a noise signal processing model, the noise signal processing model including 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] Said dB value Is the decibel of the noise signal, and the τ is the preset decibel threshold for turning on noise reduction;
[0057] The value of τ can be set by the user or the system default.
[0058] It should be noted that, according to physiological and medical research, when the environmental noise reaches 40dB, it will cause significant damage to human hea...
