摘　　要：In subjective sound quality pair-wise comparison evaluation, test time grows with square of the number of sound stimulus. For this reason, subjective evaluation of large quantity of stimulus is difficult to carry out with pair-wise comparison method. A grouped pair-wise comparison （GPC） method is proposed to greatly decrease time and difficult of subjective comparison test, in which stimuli in the whole evaluation corpus are divided into N test groups, with reference-link stimuli configured in each group. Derived from subjective results of each group, final results of all stimuli are reconstructed, and their perceptual attributes of sound quality can be analyzed. With car interior noise as example, realization of subjective sound quality evaluation with GPC method is introduced. The results of GPC evaluation are in good agreement with those obtained from paired comparison and semantic differential methods.In subjective sound quality pair-wise comparison evaluation, test time grows with square of the number of sound stimulus.
