Electronic device and method for noise alerting

An electronic device for noise alerting, comprising:

• a collecting unit to record ambient sound around the electronic device and generate corresponding sound signals;
• a volume unit to determine a volume of the ambient sound according to the sound signals;
• a first storing unit to store a first table mapping relationships between a plurality of volumes and noise grades;
• a comparing unit to obtain the noise grade corresponding to the determined volume of the ambient sound in the first table;
• a second storing unit to store a second table mapping relationships between various noise grades and solutions, wherein the solutions alert a user to take appropriate countermeasures to reduce the risk of harm to the user from excessively loud noise in time and are associated with the various noise grades;
• a calling unit to search the second table in the second storing unit to obtain the solution corresponding to the obtained noise grade of the ambient sound;
• and
• an outputting unit to output an alert to a user for recommending the obtained solution.
