In this study, the automotive interior noises under various running conditions were acquired
according to the standard GB/T 18697. Both the objective and subjective evaluations for sound quality of
vehicle interior noises were conducted and the results were saved and analyzed. The results indicate that the
psychoacoustic parameters, including loudness, sharpness and roughness obtained from the objective
evaluations have a significant correlation with the annoyance acquired through subjective evaluation, but
have little correlation with each other. The conclusions can be drawn that the loudness, sharpness,
roughness may be regarded as independent indices for Sound Quality Evaluation (SQE) and the
psychoacoustic parameters is more accurate to express human sense than the traditional SPL.
Key words: Correlation coefficient, objective evaluation , sound quality, subjective evaluation, vehicle noise, ,
