Abstract: A mode control method includes determining, by a terminal device based on a scene type of an external environment, that a processing mode used by a headset is a target mode. The target mode is one of a plurality of processing modes supported by the headset, where different processing modes correspond to different scene types, and the processing modes supported by the headset include at least two of the following modes: an active noise control (ANC) mode, a hear-through (HT) mode, or an augmented hearing (AH) mode. Processing intensity in the target mode is automatically adjusted based on an event in a current external environment. The terminal device further provides a control interface for the headset to provide selection controls for the user to select a processing mode and processing intensity. The user controls a processing mode and processing intensity of the headset based on a requirement.

Abstract: A headset has at least two functions of an active noise control (ANC) function, an ambient sound hear through (HT) function, or an augment hearing (AH) function. The headset includes a first microphone and a second microphone. The first microphone is configured to collect a first signal. The first signal indicates a sound in a current external environment. The second microphone is configured to collect a second signal. The second signal indicates an ambient sound in an ear canal of a user wearing the headset. The headset can be a left earphone or a right earphone. Processing modes or processing strengths of the left earphone and the right earphone may be the same or different. The headset obtains a target mode based on a scene type of the current external environment; and obtains a second audio signal based on the target mode, the first signal, and the second signal.
