In this paper, the psychophysical abilities and limitations of the auditory and vibrotactile modality will be discussed. A direct comparison reveals similarities and differences. The knowledge of those is the basis for the design of perceptually optimized auditory-tactile human–machine interfaces or multimodal music applications. Literature data and own results for psychophysical characteristics are summarized. An overview of the absolute perception thresholds of both modalities is given. The main factors which influence these thresholds are discussed: age, energy integration, masking and adaptation. Subsequently, the differential sensitivity (discrimination of intensity, frequency, temporal aspects and location) for suprathreshold signals is compared.

听觉和触觉感知的心理生理比较：一项调查

在本文中，将讨论听觉和触觉方式的心理生理能力和局限性。直接比较显示出异同。这些知识是设计可感知优化的听觉人机界面或多模式音乐应用程序的基础。总结了有关心理生理特征的文献数据和自己的研究结果。给出了两种模态的绝对感知阈值的概述。讨论了影响这些阈值的主要因素：年龄，能量整合，掩蔽和适应。随后，比较了阈上信号的差分灵敏度（强度，频率，时间方面和位置的区分）。
