Modelling of Tactile Measures for Whole-Body Vibrations and Their Interaction with Psychoacoustical Measures

人类在日常生活中感知到各种声学和振动刺激的组合。特别是公路和铁路上的车辆使用者，暴露在全身振动和声音的广泛组合中。感知质量在产品开发中变得越来越重要。然而，与听觉通道相比，在对触觉通道的感知质量的评估建模方面存在重大缺陷。本研究项目的目的是将心理声学测量的建模方法转变为全身振动的心理振动测量的定义和建模，从而实现整体振动-声学方法。声学和振动信号影响的多模式建模为产品的设计和评估提供了新的方法。利用心理声学的知识，将使用测试者来研究掩蔽效果。根据这些结果，将对选定的心理振动测量进行建模。此外，还必须考虑心理振动和心理声学措施的相互作用，以满足复杂的振动-声学设计的要求。这些模型将使用来自不同日常情况的信号进行验证。

Humans perceive various combinations of acoustical and vibrational stimuli in everyday situations. Especially users of vehicles on roads and railways are exposed to a wide range of combinations of whole-body vibrations and sound. Quality of perception is increasingly important in product development. Nevertheless there are significant deficits modeling the assessment of quality of perception of the tactile modality compared to the auditive modality. Objective of this research project is to transfer approaches of the modeling of psychoacoustic measures to the definition and modeling of psychovibrational measures for whole-body vibrations, thus enabling a holistic vibro-acoustical approach. A multi-modal modeling of the influence of acoustical and vibrational signals allows for new ways in designing and valuation of products. Leveraging the knowledge of psychoacoustics, masking effects will be studied using test persons. Based on those results selected psychovibrational measures will be modeled. Furthermore the interaction of psychovibrational and psychoacoustical measures has to be considered to meet the requirements of complex vibro-acoustical designs. The models will be verified using signals from different everyday situations.
