The invention discloses an objective assessment method for audio quality of a compressed domain based on distortion correction, and belongs to the communication field. The objective assessment method is characterized by comprising the following steps of: extracting characteristic parameters including code rate, scale factor, pre-echo distortion, frequency distortion and speech coding distortion from a compressed audio stream; performing basic assessment on the audio quality according to the code rate and the scale factor, and giving an initial objective assessment score; and judging whether distortions exist according to the characteristic parameters of the pre-echo distortion, the frequency distortion and the speech coding distortion, and correcting the objective assessment score when the distortions exist so as to obtain a final objective assessment score. According to the objective assessment method disclosed by the invention, factors which influence the audio quality are taken full consideration, so that the objective assessment method can be used for simulating a subjective assessment result in a better manner.
