Techniques for alarm sound processing in noisy environments

An electronic device, comprising:

• one or more processors, a memory, and a wireless communication module, wherein
• the memory and the wireless communication module are coupled to the one or more processors, the memory is configured to store computer program code, the computer program code comprises computer instructions, and when the one or more processors execute the computer instructions, the one or more processors are caused to:
• obtain audio information, wherein the audio information is obtained by collecting sounds of an environment in which an electronic device is located;
• determine that the audio information comprises a first alarm sound;
• determine first location information of the first alarm sound based on the audio information, wherein the first location information is used to indicate an acoustic source direction of the first alarm sound;
• determine that the audio information and previous audio information that comprises a second alarm sound have not been obtained within a preset duration and, in response:
• determine a first sound, wherein the first sound comprises second location information, the second location information is used to indicate the acoustic source direction of the first alarm sound, the second location information is the same as or different from the first location information, the first sound is a 3D notification sound, and the 3D notification sound is a third alarm sound carrying a direction,
• send the first sound to headphones, and
• play, by the headphones, the first sound comprising the second location information;
• and
• determine that the audio information and the previous audio information that comprises the second alarm sound are obtained within the preset duration and, in response:
• determine that a difference between the first location information of the first alarm sound in the audio information and first location information of the second alarm sound in the previous audio information that comprises the second alarm sound are within a preset range, detecting that the first alarm sound in the audio information and the second alarm sound in the previous audio information that comprises the second alarm sound are a same sound, and generating a distance coefficient, wherein the distance coefficient is used to represent an energy gain of the audio information relative to the previous audio information that comprises the second alarm sound;
• determine a second sound, wherein the second sound comprises the second location information and the energy gain;
• and
• play, by the headphones, the second sound comprising the second location information and the energy gain.

A non-transitory computer storage medium, configured to store a computer program, wherein when the computer program is executed by a processor, the the processor is caused to:

• obtain audio information, wherein the audio information is obtained by collecting sounds of an environment in which an electronic device is located;
• determine that the audio information comprises a first alarm sound;
• determine first location information of the first alarm sound based on the audio information, wherein the first location information is used to indicate an acoustic source direction of the first alarm sound;
• determine that the audio information and previous audio information that comprises a second alarm sound have not been obtained within a preset duration and, in response:
• determine a first sound, wherein the first sound comprises second location information, the second location information is used to indicate the acoustic source direction of the first alarm sound, the second location information is the same as or different from the first location information, the first sound is a 3D notification sound, and the 3D notification sound is a third alarm sound carrying a direction,
• send the first sound to headphones, and
• play, by the headphones, the first sound comprising the second location information;
• and
• determine that the audio information and the previous audio information that comprises the second alarm sound are obtained within the preset duration and, in response:
• determine that a difference between the first location information of the first alarm sound in the audio information and first location information of the second alarm sound in the previous audio information that comprises the second alarm sound are within a preset range, detecting that the first alarm sound in the audio information and the second alarm sound in the previous audio information that comprises the second alarm sound are a same sound, and generating a distance coefficient, wherein the distance coefficient is used to represent an energy gain of the audio information relative to the previous audio information that comprises the second alarm sound;
• determine a second sound, wherein the second sound comprises the second location information and the energy gain;
• and
• play, by the headphones, the second sound comprising the second location information and the energy gain.
