Claim Text:
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.
