A voice aware audio system and a method for a user wearing a headset to be aware of an outer sound environment while listening to music or any other audio source. An adjustable sound awareness zone gives the user the flexibility to avoid hearing far distant voices. The outer sound can be analyzed in a frequency domain to select an oscillating frequency candidate and in a time domain to determine if the oscillating frequency candidate is the signal of interest. If the signal directed to the outer sound is determined to be a signal of interest the outer sound is mixed with audio from the audio source.

The invention provides a call terminal and an adaptive volume adjustment method and system thereof. The method comprises the following steps: when the call terminal is used for making a call, acquiring a value of a first distance between the call terminal and the face of a user through a distance sensor of the call terminal; calculating a value of a second distance between a sound pickup and a sound source according to a predetermined calculation rule and the acquired first distance value; and correspondingly adjusting a gain of the sound pickup according to the change of the second distance value.
