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.
