Abstract
An audio signal adjusting method is disclosed, which comprises steps of: determining an environment noise level; calculating a ratio between an environment noise level and an output audio signal level to form a measuring value; comparing the measuring value with a predetermined threshold as an audio comfort value; and determining whether or not to adjust an audio signal parameter according to the comparison result. If the comparison result is incorrect, then the audio signal parameter is adjusted, and the output audio signal should be outputted according to the adjusted audio signal parameter. The audio signal adjusting method can satisfy the different user needs on different environment types.
