本文探讨了如何从心理声学实验不同类型的数据可以结合起来，使进一步了解的机制，声音感知。两项研究进行了短时间的听觉警报。首先，进行了一项实验，参与者对听觉警报之间的差异进行评级。这导致了二维多维缩放解决方案。第二，实验中，参与者评估的刺激与语义描述符，并评价他们的情绪反应的声音进行。这个实验的输出是一组减少潜在的感知和情感维度。两个实验的结果，然后整合使用多维知觉展开和一组中介分析。整合分析表明，语义描述词的认知范畴化部分是由对声音的情绪反应所介导的。结果进行了讨论有关的理论的听觉感知和情绪反应分类。
This paper investigates how different types of data from psychoacoustical experiments may be combined to render further knowledge about the mechanisms underlying sound perception. Two studies were conducted with auditory alerts of short duration. First, an experiment where participants rated the dissimilarity among the auditory alerts was performed. This resulted in a two-dimensional multi-dimensional scaling solution. Second, an experiment where participants evaluated the stimuli with semantic descriptors and rated their emotional reactions to the sounds was performed. The output of this experiment was a reduced set of underlying perceptual and emotional dimensions. The results of the two experiments were then integrated by the use of multi-dimensional perceptual unfolding and a set mediation analyses. The integrative analyses showed that part of the cognitive categorization of the semantic descriptors was mediated by the emotional reactions to the sounds. The results are discussed in relation to theories of auditory perception and emotional response categorization.
