A system and a method for audio adjustment are provided. The method includes following steps. A first output audio signal generated from the under-test audio playback device according to a frequency response test signal is received. The first output audio signal is analyzed to generate a set of suggested equalization parameter. A set of equalization parameters are adjusted according to the suggested equalization parameters, and a sound test signal is generated from an original sound signal according to the equalization parameters and output to the under-test audio playback device. A second output audio signal is generated from the under-test audio playback device in response to the sound test signal. Whether the auditory effect of the second output audio signal is close to the original sound signal or matches the user's need is determined. The equalization parameters are adjusted when the auditory effect of the second output audio signal is not close to the original sound signal or the user is not satisfied with the auditory effect.
