【摘要】 催眠是一种常见的心理学现象,声音的催眠效果也广为人知。国内外研究大多集中从医学角度对这个问题进行研究。通过改进心理声学中的成对比较法对大量声音样本的催眠效果进行实验研究。一方面设置三角循环误判提高实验准确度,另一方面通过分组成对比较法节省实验时间,提高实验效率。通过主观评价结果结合声信号频谱特点的分析表明,大多数具有催眠效果的声音主要频率成分集中在中频(250~800 Hz),且一般不具有明显的高频强线谱成分。更多还原

【Abstract】 Hypnosis is a very common phenomenon of psychology,and the hypnotic effects of sound are also well-known.Researches at home and abroad with respect to this question are mostly from the medical perspective.In this paper,an experimental study on hypnotic effects of amounts of sound samples is conducted via the improved paired comparisons of psychoacoustics.On one hand,the accuracy of the experiments is promoted by using the triangle loop misjudgment.On the other hand,the time is saved and the efficiency is raised by carrying on the grouping paired comparisons.Combining the results of subjective evaluation and the analysis of the characteristics of the sound spectrum,that main frequency components of the hypnagogic sound are almost at the middle frequencies(250 ~ 800 Hz) and evident strong line spectrum of high frequencies are not contained generally.更多还原
