Sensibility evaluation of sound using onomatopoeic representation

本研究的目的是发展利用拟声词获取声音的听觉印象和声学特性等感性信息的技术。为了明确声音的声学特性、听觉印象和拟声特征之间的关系，本研究首先以环境声音为刺激进行了两类心理声学实验。一种是使用拟声表征的自由描述实验。参与者写下每个声音刺激的拟声表示。另一个是使用语义差分方法测量与声音刺激相关的印象。这些实验结果表明，拟声表征可以用于识别环境声音的各种声学特性。此外，还发现了声音刺激下的声学特性、拟声特征和听觉印象之间的关系。例如，浊音辅音经常被用来表示频率范围低于1khz的声音，让人产生“有力”、“黑暗”和“沉闷”的印象。在接下来的步骤中，讨论了使用拟声词作为交流听觉印象感性信息的手段的可行性。拟声表征呈现给参与者，他们评估由拟声表征引起的声音印象。结果表明，拟声表征诱发的声音印象可归纳为三个因素；响度、音高和持续时间。这一结果表明，我们可以利用拟声表征来传达上述三种声音印象的敏感性信息。在最后阶段，为了建立使用拟声表征来预测印象的模型，我们测量了由二人拟声表征引起的声音印象。采用Hayashi的量化理论（Quantification Theory I. Less）建立了以拟声表示中的语音参数为自变量的预测模型

The goal of this study is the development of the technique to obtain the sensibility information such as auditory impression and acoustic property of sound using onomatopoeia. In the first step of this study, to clarify the relationship among acoustic property of sound, auditory impression and onomatopoeic feature, two kinds of psychoacoustical experiments were carried out using environmental sounds as stimuli. One was the free description experiment using onomatopoeic representation. Participants wrote down an onomatopoeic representation for each sound stimulus. The other was the measurement of impressions associated with sound stimuli using the semantic differential method. The results obtained in these experiments indicated that onomatopoeic representations could be useful for identifying the various acoustic properties of environmental sounds. Furthermore, the relationships among the acoustic properties, onomatopoeic features, and auditory impressions associated with sound stimuli … More were found. For example, the voiced consonant was often used to represent sounds displaying components in the frequency range below about 1 kHz, inducing impressions of "powerfulness" along with "darkness" and "dullness."In the next step, the availability of using onomatopoeia as a means to communicate the sensibility information concerning auditory impression was discussed. Onomatopoeic representations were presented to participants, and they evaluated the impressions of sounds evoked by onomatopoeic representations. As a result, the impressions of sounds evoked by onomatopoeic representations were summarized in the three factors ; loudness, pitch and duration. This result indicated that we could communicate the sensibility information concerning the above three impressions of sound using onomatopoeic representation.In the final stage, to develop the model to predict the impressions using onomatopoeic representation, the impressions of sounds evoked by 2-morae onomatopoeic representations were measured. The prediction models, in which the independent variables were phonetic parameters included in onomatopoeic representations, were developed using Hayashi's Quantification Theory I. Less
