声源辨识个体差异研究

Study on individual differences in the Identification of sound source

为研究声源辨识中的个体差异,分别针对声源材料和尺寸设计并完成了声音不相似性的2个主观评价实验。实验采用被击板的合成声,通过成对比较法获得声音的不相似性评价,对不相似矩阵进行CLASCAL多维尺度分析,得到被试间差异性规律。结果表明:材料不相似性评价中,被试间的个体差异主要和性别有关;尺寸不相似性评价中,受训并没有增加被试间的差异性。

Two subjective evaluation experiments were designed and performed to investigate the individual differences amonglisteners in the identification of the material and size properties of impacted plates. Sound samples were synthesized. sound, according to equations given for the motion of plates. The dissimilarity ratings from the paired comparison experi- ment were conducted and analyzed with an extended version of the multidimensional scaling algorithm,i, e. Latent class scaling, CLASCAL, which can estimate the number of latent classes of subjects. The results show that in material identifi- cation, the significant difference among different classes is the sex. During the size identification experiment, training for listeners does not have essential contacts with individual differences.
