In this embodiment, the television terminal adjusts an output volume value according to the environment volume difference value and the current television volume value. The television end judges whether the environment volume difference is larger than 0, if the environment volume difference is larger than 0, the television end promotes the current television volume value to obtain a first target volume value; if the environment volume difference is smaller than 0, the television end reduces the current television volume value to obtain a second target volume value, and after the television end obtains the output volume value, the television end controls the output volume value to output, so that the ears of people can achieve the best listening effect.
