Many studies have been presented regarding the assessment of different perceptual attributes when playing violins, highlighting the large influence of the tactile component of the overall multi-modal event on instrument ratings. To date, however, little is known about how different properties of the perceived vibration signal affect the assessment of different perceptual attributes. This relationship will be systematically investigated in this research project. To this end, a new method will be developed first which makes it possible to modify tactile and auditory feedback of a violin independently and arbitrarily. Thus, specific properties of the multi-modal event can be modified while others are kept constant. This is not possible when directly comparing violins as it has often been described in the literature. For this purpose, a "virtual prototype" (v.p.) of a violin will be developed and implemented. This instrument is based on an electric violin, which has the conventional ergonomics of an acoustic violin. It will be equipped with a sound pickup system, a signal processing unit, headphones and vibrators. This allows to realistically reproduce both the sound and the vibrations at the contact points to the instrument. Thus, actual acoustic violins can be emulated or synthetic violins can be created. In addition to being played, this instrument can also be used as an audio-tactile playback device. Furthermore, a measurement system is to be developed which makes it possible to measure transfer functions on acoustic violins that are required for emulation on the v.p.. In addition, this system can be used to make audio-tactile recordings with violins in order to play them back via the v.p..Interactive and non-interactive perceptual experiments will be conducted with the v.p.. First, in the non-interactive mode, it will be investigated how different properties of the vibration signal affect the assessment of perceptual attributes. Therefore, the influence of primitive vibration signals of different frequencies and amplitudes is investigated at the beginning. Then, more complex signals based on vibration recordings of acoustic violins will be used. Based on the results of these experiments, a model for the relationship between vibration characteristics and the evaluation of violins will be developed. Finally, the non-interactive experiments will be compared to interactive experiments. For this purpose, test subjects are to play the v.p. themselves and evaluate the same vibration characteristics as before. Thus, on the one hand the influence of the active interaction can be highlighted and on the other hand the additional tactile stimulus via the violin bow can be evaluated.

许多研究已经提出了关于不同的感知属性的评估时，演奏小提琴，突出了大的影响力的触觉组件的整体多模态事件对仪器的评级。然而，迄今为止，很少有人知道如何感知振动信号的不同属性影响不同的感知属性的评估。在本研究项目中，将系统地研究这种关系。为此，将首先开发一种新的方法，该方法可以独立地和任意地修改小提琴的触觉和听觉反馈。因此，可以修改多模态事件的特定属性，而其他属性保持不变。当直接比较小提琴时，这是不可能的，因为它经常在文献中描述。为此，一个“虚拟原型”（v. p.）一个小提琴将被开发和实施。这种乐器是基于一个电子小提琴，它具有传统的人体工程学的声学小提琴。它将配备一个拾音系统、一个信号处理单元、耳机和振动器。这允许在与乐器的接触点处真实地再现声音和振动。因此，可以模拟实际的声学小提琴，或者可以创建合成小提琴。除了演奏之外，这种乐器还可以用作音频触觉播放设备。此外，还将开发一种测量系统，该系统可以测量在v. p.上进行仿真所需的声学小提琴上的传递函数。此外，该系统还可用于制作小提琴的音频-触觉记录，以便通过v. p.播放。交互式和非交互式知觉实验将与副总裁进行。首先，在非交互模式下，将研究振动信号的不同属性如何影响感知属性的评估。因此，不同频率和振幅的原始振动信号的影响进行了研究。然后，将使用基于声学小提琴振动记录的更复杂的信号。基于这些实验的结果，将开发一个模型的振动特性和小提琴的评价之间的关系。最后，将非交互式实验与交互式实验进行比较。为此，受试者将自己演奏副总裁，并评估与以前相同的振动特性。因此，一方面可以突出主动交互的影响，另一方面可以评估经由小提琴弓的附加触觉刺激。
