Abstract
An approach for the characteristic analysis of the noise of auto horizontal driving machine (HDM) based on the objective parameters of sound quality was presented. Two sets of the sound quality objective parameters from the abnormal and normal HDMs, which were subjectively classified and judged by juries, were acquired, calculated, compared and analyzed. Thus, the subjective differences and characteristics of the noise of HDMs were objectively quantified. In addition, the frequencies of the noise from the abnormal HDMs were identified based on the time-frequency analysis and the comparison with the curves of objective parameters vs. time. Finally, the frequency components of the noise from the abnormal HDMs can then be further identified by the interactive filtering and acoustic playback. The results show that the two objective parameters of sound quality, sharpness and tonality, are the most effective objective parameters for the identification of the noise of the abnormal HDM.关键词
