Evaluation and analysis of auditory attributes for vehicle noise based on Chinese expressions

Dimensionality and expressions in Chinese of auditory attributes for vehicle noise are investigated. First, three questionnaire surveys are accomplished to obtain a number of auditory descriptors in Chinese, and then based on Paired Comparison and Semantic Differential approaches, two subjective jury tests are accomplished to obtain a similarity matrix and ranked descriptors. Finally, by use of Multidimensional Scaling and Principal Component Analysis, auditory attributes for equal-loudness vehicle noise are determined and then is expressed in terms of three Chinese adjectives corresponding to 'roughness', 'sharpness' and 'fluctuation'.
