1. A user hearing protection method, comprising:
after an electronic device enables a hearing protection mode, when a current sound output mode of the electronic device is a headset output, obtaining current-frame sound source data;
obtaining, based on the current-frame sound source data, sound pressure output by a headset connected to the electronic device;
comparing the sound pressure with a predetermined sound pressure threshold; and
if the sound pressure is greater than the predetermined sound pressure threshold, performing an instantaneous sound pressure over-standard warning and an instantaneous sound pressure over-standard protection operation,
wherein the obtaining, based on the current-frame sound source data, sound pressure output by a headset connected to the electronic device comprises:
obtaining a current usage scenario of the headset by a scenario obtaining submodule of an obtaining module, wherein the current usage scenario comprises audio play, video play, gaming, or making a call;
obtaining, based on the current-frame sound source data and a sound effect change and a gain value that are of a channel corresponding to the current usage scenario, a digital signal value output to a headset interface of the electronic device;
obtaining, based on the digital signal value and a digital-to-electrical conversion gain value of the electronic device, a voltage value output to the headset interface; and
obtaining, based on the voltage value and an electro-acoustic conversion coefficient of the headset, sound pressure output by the headset.
