Abstract:
A volume adjustment method and apparatus, and a terminal is presented. Perform analysis on the collected sound signal surrounding a user terminal, to obtain composition information, where the composition information includes sound types included in the sound signal and proportions of sounds of the various types, and the sound types include blank sound, human sound, and noise; determine a current scene mode of the user terminal according to the composition information; and adjust volume of the user terminal according to the determined scene mode, thereby significantly reducing occurrence of a case, caused by mistaken determining of the scenario, in which play volume adjustment does not conform to the scenario, and enhancing user experience.

Claim (Index 5):
The method of  claim 4 , wherein classifying, according to the calculated sound frequency, each piece of audio data according to blank sound, human sound, and noise comprises:\n determining whether the sound frequency of each piece of audio data is in a range of 20 hertz (Hz) to 20000 Hz; calculating a fundamental frequency of the audio data when determining that the sound frequency of the audio data is in the range of 20 Hz to 20000 Hz; determining that the audio data is a human sound when determining that the fundamental frequency is in a range of 85 Hz to 255 Hz; determining that the audio data is noise when determining that the fundamental frequency is out of the range of 85 Hz to 255 Hz; and determining that the audio data is a blank sound when determining that the sound frequency of the audio data is out of the range of 20 Hz to 20000 Hz.
