Auralization is a technique which allows the rendering of realistic 3D audio based on virtual spatial scenes. Certain sound propagation parameters (or so-called auralization parameters) such as propagation delay, atmospheric attenuation, and spreading loss, can be derived from physics-based simulations of virtual scenes. These parameters are essential to rendering plausible sound signals in a spatial context. In the auralization of complex scenes, the simulations can be very computationally demanding. This can become a bottleneck for real-time auralization: The amount of…

Stienen: Real-time auralisation of outdoor sound propagation

Juni 3 @ 13:00 - 14:00

Auralisation describes the process of generating and presenting audible sound using computer programs and audio hardware. Since the result is perceived naturally by the human's auditory system, a demonstration by means of auralisation is easily comprehensible and does neither require background knowledge nor expertise. Producing auralisation under real-time constraints increases the implementation demands significantly. Real-time auralisation is required in applications that respond to user interaction, for example, in interactive Virtual Reality (VR) environments. Dynamically moving sound sources and receivers evoke…

From the beginning of their auditory development, children are immediately confronted with the challenge of orienting themselves in complex acoustic situations. Whether a parent’s voice or a passing vehicle, it is crucial to distinguish an auditory signal from the acoustic environment. Spatially distributed sound sources, distracting sounds, and disturbing background noise, for example, impede this listening process. The ability to focus on the relevant target source while blocking out simultaneous distracting sounds in a multi-layered acoustic environment is known as…
