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.

虚拟声学环境（VAE）的感知已经被研究多年。交互式翻译使听众能够探索听觉场景的更多细节。尤其是聆听位置的连续变化很少受到研究。另一方面，多项研究表明，动态聆听者能够更准确地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听众的距离感知。此外，可以更准确地感知声源的方向性和范围。到目前为止，对于是否以及以何种方式可以在 VAE 中观察到这些效应仅进行了初步研究。目前尚不清楚模拟算法的简化如何影响自然感知。此外，问题仍然是某些方面的简化或缺失再现是否被视为质量方面的缺陷。在所请求的项目中，对虚拟听觉环境关于不断变化的聆听视角的感知进行了研究。除了距离的连续变化之外，还将研究虚拟声源和虚拟听众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建中起着重要作用。然而，听众运动过程中对室内声学的感知尚未完全了解。该项目的目标是估计位置动态双耳合成的某些技术参数与 VAE 感知之间的联系。调查将重点关注翻译听众运动的贡献。
