Taking the test abnormal sound samples of vibration abnormal sound in car seats as the research object,using the grading method to subjectively evaluate abnormal sound samples,obtain subjective evaluation scores reflecting seat noise,and calculate objective evaluation parameters for the abnormal noise samples.Through the correlation analysis of subjective and objective evaluation results,it is found that the A-weighted sound pressure level and loudness have an impact on subjective evaluation results.However,there is a more significant correlation between objective evaluation parameter loudness and subjective evaluation results.Loudness can accurately reflect subjective evaluation scores,and verified the reliability of subjective evaluation results of abnormal noise.
