Real-time building acoustics noise auralization and evaluation of human cognitive performance in virtual reality
* Presenting author
There is a concern about steadily growing annoyance due to noise in private and commercial work offices that leads towards reduced power of concentration during mental work and losses of working performance. This paper describes a method to assess the influence of noise disturbances on human cognitive performance in buildings in compliance with standardized data formats of sound insulation and building structure geometries, which are caused by the building materials and constructions. An interface is established between real-time auralization of buildings in virtual reality and evaluation of human working performance under different conditions. In this context, a real-time building acoustic auralization framework in 3D audio-visual technology is developed to introduce more realism and contextual features into psychoacoustic experiments, which help to better analyse and interpret the noise impact in building situations depending on the actual activity such as working and learning. Psychoacoustic experiments are performed by presenting a virtual building scenario to the user by Head Mounted Devices. Initial results of noise effects on human performance are presented in an ecologically valid way.
