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

在日常生活中，人类感知到各种声音和振动刺激的组合。特别是公路和铁路上的车辆使用者，他们暴露在各种全身振动和声音的组合中。感知质量在产品开发中越来越重要。然而，与听觉模态相比，触觉模态的感知质量评估模型存在显著缺陷。本研究项目的目的是将心理声学测量的建模方法转移到全身振动的心理振动测量的定义和建模中，从而实现整体振动声学方法。声学和振动信号影响的多模态建模为设计和评估产品提供了新的方法。利用心理声学的知识，掩蔽效应将使用测试人员进行研究。基于这些结果，选定的心理振动测量将被建模。此外，为了满足复杂振声设计的要求，还必须考虑心理振动和心理声学措施的相互作用。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.
