Influence of translatory motion of listeners on the perception of virtual acoustic environments

对虚拟声环境的感知已经进行了多年的研究。互动式翻译使听者能够探索更多听觉场景的细节。尤其是听音位置的不断变化，很少受到研究。另一方面，多项研究表明，动态听者对其声环境的不同细节的感知精度更高。例如，运动视差效果可以促进翻译听者的距离感知。此外，声源的指向性和范围被更准确地感知。是否以及以何种方式可以在VAEs中观察到这些影响，迄今为止还只是初步的研究。目前尚不清楚仿真算法的简化如何影响自然感知。此外，问题仍然存在，某些方面的简化或缺失复制是否被视为质量方面的缺陷。在请求的项目中，关于变化的听力视角的虚拟听觉环境的感知有待研究。除了距离的连续变化外，还将研究虚拟声源与虚拟听者之间方向的相对变化。此外，虚拟房间的感知在虚拟场景的创造中起着重要的作用。然而，听者在运动过程中对室内声学的感知并没有完全被理解。本项目的目标是估计位置动态双耳合成的某些技术参数与VAEs感知之间的联系。研究的重点是翻译听者运动的贡献。

The perception of virtual acoustic environments (VAEs) has been studied for years. An interactive translation enables the listener exploring more details of the auditory scene. Especially the continuous change of the listening position has rarely been subject to research.On the other hand multiple studies have shown, that dynamic listeners perceive different details of their acoustic environment with a higher accuracy. For example, motion parallax effects can facilitate the distance perception of a translating listener. Additionally, the directivity and extent of a sound source is perceived more accurately.Whether and in which way these effects can be observed in VAEs has been studied only rudimentary so far. It is still not clear, how simplifications in the simulation algorithms affect the natural perception. Furthermore the question remains whether a simplified or missing reproduction of certain aspects are perceived as a drawback regarding quality.In the requested project, the perception of virtual auditory environments regarding a changing listening perspective is subject to research. Besides aspects of continuous changes in distance, the relative changes in orientation between the virtual sound source and the virtual listener will be investigated. Furthermore, the perception of the virtual room plays an important role in the creation of virtual scenes. However, the perception of room acoustics during the movement of a listener is not completely understood.Target of this project is the estimation of connections between certain technical parameters of position dynamic binaural synthesis and the perception of VAEs. The investigations will focus on the contribution of translational listener movement.
