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.

虚拟声环境的感知问题已经研究了很多年。交互式翻译使听众能够探索听觉场景的更多细节。特别是连续变化的收听位置很少受到研究。另一方面，多项研究表明，动态收听者以更高的准确度感知其声学环境的不同细节。例如，运动视差效果可以促进翻译收听者的距离感知。此外，声源的指向性和范围被更准确地感知。这些效应是否以及如何在VAE中被观察到，迄今为止还只是初步的研究。目前还不清楚，如何简化的模拟算法影响自然的看法。此外，问题仍然是是否简化或缺失的某些方面的再现被视为一个缺点，关于质量。在所要求的项目中，虚拟听觉环境的感知关于不断变化的听的角度是受研究。除了距离的连续变化的方面，虚拟声源和虚拟听众之间的取向的相对变化将被研究。此外，虚拟房间的感知在虚拟场景的创建中起着重要的作用。然而，在一个听者的运动过程中的室内声学的感知是不完全理解的，这个项目的目标是位置动态双耳合成的某些技术参数和VAE的感知之间的联系的估计。调查将集中在翻译听话人运动的贡献。
