5. A sound quality evaluation system, comprising:
an audio recording module, configured to define a plurality of playback devices as a first group and a second group, and record respectively playback of at least one test audio file on the first group and the second group, to generate a plurality of pieces of first audio data and a plurality of pieces of second audio data;
a calculation module, configured to divide respectively each piece of first audio data and each piece of second audio data, to generate a plurality of first group frequency bands and a plurality of second group frequency bands, and calculate and process respectively the first group frequency bands and the second group frequency bands, to obtain a plurality of first evaluation scores of the first group and a plurality of second evaluation scores of the second group;
a communication module, configured to capture first sound quality ranking information corresponding to the first group from a reference source; and
a processing module, configured to refer to the first sound quality ranking information to adjust correspondingly the first evaluation scores, to further obtain a first reference model, and adjust correspondingly the second evaluation scores according to the first reference model, to further obtain second sound quality ranking information of the second group.
