Mode control method and apparatus, and terminal device

A method implemented by a terminal device, wherein the method comprises:

• obtaining a target mode, wherein the target mode is one of a plurality of processing modes supported by a headset, and wherein the processing modes comprise at least two of the following modes:
• an active noise control (ANC) mode;
• a hear-through (HT) mode;
• or
• an augmented hearing (AH) mode;
• determining a target processing intensity in the target mode based on a scene type of a current external environment, wherein different scene types correspond to different processing intensities within a same processing mode, wherein the target processing intensity indicates a processing intensity at which the headset performs a processing function corresponding to the target mode, and wherein determining the target processing intensity comprises obtaining at least one of a feedforward (FF) filtering coefficient, a feedback (FB) filtering coefficient, or a hear-through (HT) filtering coefficient that corresponds to the target scene;
• and
• sending, to the headset, the target processing intensity.

A method implemented by a terminal device, wherein the method comprises:

• establishing a communication connection to a headset that supports an active noise control (ANC) function and a hear-through (HT) function;
• displaying an interface that sets functions of the headset, wherein the interface comprises a first option for an event sound enhancement function, and wherein an event sound meets a preset event condition and is in an external environment;
• determining a target processing intensity of the event sound enhancement function based on a scene type of the external environment;
• wherein different scene types correspond to different processing intensities within a same processing mode, wherein determining the target processing intensity comprises obtaining at least one of a feedforward (FF) filtering coefficient, a feedback (FB) filtering coefficient, or a hear-through (HT) filtering coefficient that corresponds to the scene type;
• controlling both the ANC function and the HT function to be in an enabled state when the first option is enabled;
• and
• sending, to the headset, the at least one filtering coefficient to instruct the headset to perform the event sound enhancement function at the target processing intensity.

A method implemented by a terminal device, wherein the method comprises:

• establishing a communication connection to a headset that supports a hear-through (HT) function;
• displaying an interface that sets functions of the headset, wherein the interface comprises a first option for controlling the HT function;
• activating the HT function when the first option is enabled;
• adding, to the interface, a second option for enhancing an event sound using an event sound enhancement function, wherein the event sound meets a preset event condition and is in an external environment;
• determining a target processing intensity of the event sound enhancement function based on a scene type of the external environment, wherein different scene types correspond to different processing intensities within a same processing mode, wherein determining the target processing intensity comprises obtaining at least one of a feedforward (FF) filtering coefficient, a feedback (FB) filtering coefficient, or a hear-through (HT) filtering coefficient that corresponds to the scene type;
• and
• controlling the headset to increase a signal-to-noise ratio of the event sound based on the target processing intensity when the second option is enabled, wherein a higher signal-to-noise ratio of the event sound indicates a higher energy ratio of the event sound.
