Devices and methods for audio volume adjustment

1. A processor-implemented method for audio volume adjustment, comprising:

acquiring, using a sound collecting device, a noise volume level of current ambient noise and a first volume level of a first current audio signal of a first application;

comparing, using one or more data processors, the first volume level and the noise volume level to obtain a first comparison result;

adjusting the first volume level based on at least information associated with the first comparison result and a reference volume level;

in response to switching from the first application to a second application, acquiring a second volume level of a previous audio signal of the second application;

comparing the second volume level with the adjusted first volume level to achieve a second comparison result; and

adjusting a third volume level of a second current audio signal of the second application based on at least information associated with the second comparison result.

2. The method of claim 1 , wherein the adjusting a third volume level of a second current audio signal of the second application based on at least information associated with the second comparison result includes:

in response to the second volume level being higher than the adjusted first volume level, increasing the third volume level according to the second volume level.

3. The method of claim 1 , wherein the adjusting a third volume level of a second current audio signal of the second application based on at least information associated with the second comparison result includes:

in response to the second volume level being lower than the adjusted first volume level, decreasing the third volume level according to the second volume level.

4. The method of claim 1 , further comprising:

acquiring a user volume level from manual adjustment of a user; and

adjusting the third volume level according to the user volume level.

5. A device for audio volume adjustment, comprising:

a first acquisition module configured to acquire a noise volume level of current ambient noise using a sound collecting device;

a second acquisition module configured to acquire a first volume level of a first current audio signal of a first application using the sound collecting device;

a first comparison module configured to compare the first volume level and the noise volume level to obtain a first comparison result;

a first adjustment module configured to adjust the first volume level based on at least information associated with the first comparison result and a reference volume level;

a fourth acquisition module configured to, in response to switching from the first application to a second application, acquire a second volume level of a previous audio signal of the second application;

a second comparison module configured to compare the second volume level with the adjusted first volume level to achieve a second comparison result; and

a third adjustment module configured to adjust a third volume level of a second current audio signal of the second application based on at least information associated with the second comparison result.

6. The device of claim 5 , wherein the third adjustment module is further configured to, in response to the second volume level being higher than the adjusted first volume level, increase the third volume level according to the second volume level.

7. The device of claim 5 , wherein the third adjustment module is further configured to, in response to the second volume level being lower than the adjusted first volume level, decrease the third volume level according to the second volume level.

8. The device of claim 5 , further comprising:

a fifth acquisition module configured to acquire a user volume level from manual adjustment of a user; and

a fourth adjustment module configured to adjust the third volume level according to the user volume level.
