Embodiments of this application provide a user hearing protection method, apparatus, and electronic device. In the method, after an electronic device enables a hearing protection mode, when an audio output mode is a headset output, sound pressure output by the headset is obtained based on current-frame sound source data; when the sound pressure is greater than a predetermined sound pressure threshold, an instantaneous sound pressure over-standard warning is performed, and an instantaneous sound pressure over-standard protection operation is performed on the electronic device. In addition, after the output sound pressure is obtained, the sound pressure may be stored, and a sound dose accumulated to a current moment may be determined based on the stored historical sound pressure data; when the sound dose is greater than a predetermined sound dose standard value, sound dose over-standard warning and a sound dose over-standard protection operation are performed.

User hearing protection method, apparatus, and electronic device

This application provides a battery protection circuit, a battery protection board, a battery, and a terminal device. The battery protection circuit includes: a first detection unit; a second detection unit; and a current detection element, a first switch unit, and a second switch unit that are configured to connect to an electrochemical cell in series, to form a charging loop or a discharging loop. The first detection unit corresponds to the first switch unit, and the second detection unit corresponds to the second switch unit. Each detection unit controls, based on a detected voltage at two ends of the same current detection element, a corresponding switch unit to be closed or opened, so as to control the loop to be closed or opened. The first detection unit and the second detection unit detect the voltage at the two ends of the same current detection element to detect a current passing through the electrochemical cell, so that a quantity of current detection elements in the battery protection circuit can be effectively reduced, to reduce impedance of the battery protection circuit.
