Systems, devices and methods are provided for audio volume adjustment. For example, a noise volume level of current ambient noise and a first volume level of a first current audio signal of a first application are acquired using a sound collecting device. The first volume level and the noise volume level are compared using one or more data processors to obtain a first comparison result. The first volume level is adjusted based on at least information associated with the first comparison result and a reference volume level. |
