First, this study focuses on the following three aspects in the case of listening to Japanese mono-syllable and/or word acoustical signal under the meaningless steady noise : annoyance caused by noise, speech audibility of the audio signal, and the listening score. Concretely, listening psychological experiments using various audio signals and noises were carried out. From the experimental results, relationships between the above three aspects and the amplitude and frequency characteristics of the audio signal and those of noise were considered quantitatively, by introducing eight indices. The following results were obtained.1. When SN_A is used, although it was suitable for evaluating the psychological impression of noise, not suitable with regard to the psychological impression of audio signal and listening score.2. When SI is used, only in the case of mono-syllable acoustical signal, there was a correspondence to the three aspects.3. When WSPD is used, it was the best for evaluating the three aspects.4. From the consideration on the estimation and/or prediction problems of the psychological impressions of noise and audio signal, and the listening score of audio signal, derived by using WSPD, the validity and the applicability were confirmed experimentally, and reasonable results were obtained.

首先，本研究主要从以下三个方面对在无意义的稳态噪声环境下听日语单音节和/或单词声信号的情况进行研究：噪声引起的烦恼、音频信号的言语可听度和听力得分。具体而言，使用各种音频信号和噪声进行了听力心理实验。从实验结果来看，通过引入8个指标，定量地考虑了上述3个方面与音频信号和噪声的幅度和频率特性之间的关系。得到以下结果.当使用SN_A时，虽然SN_A适用于评价噪声的心理印象，但不适用于评价音频信号的心理印象和听力评分.当使用SI时，只有在单音节声学信号的情况下，这三个方面存在对应关系.使用WSPD时，对这三个方面的评价效果最好.从噪声和音频信号的心理印象的估计和/或预测问题的考虑，和音频信号的听力分数，通过使用WSPD，实验证实了有效性和适用性，并得到合理的结果。
