摘要
研究了等响度车辆噪声听觉属性的空间维度及其汉语表述。首先通过问卷调查确定评价车辆噪声听觉属性的汉语描述词,然后完成基于成对比较法和语义细分法的主观评价实验,获得听觉属性的不相似度矩阵及描述词的等级顺序。最后,利用多维尺度分析和主成分分析法得到独立的用中文表达的车辆噪声听觉属性,结果表明:对于等响度的车辆噪声,其听觉属性可以用三个维度表示,分别用"粗糙"、"刺耳"和"起伏"描述。
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＂.
