Title Prediction, visualization, and auralization of noise in industrial workrooms during computer "walk-through"
Bibliographic information Mar.-Apr. 1999, Vol.47, No.2, p.65-70. Illus. 10 ref.
Abstract A new approach to the modelling of noise in industrial workrooms is presented. The objectives, approach and technical basis of the system, particularly regarding the novel prediction and auralization (acoustical-virtual-reality) aspects are discussed. New empirical models used to predict noise levels, reverberation times and fitting densities are presented. Methods for realizing simplified auralization of the predicted noise using a soundcard and headphones are discussed. A graphical user interface, which enables visualization of the workroom floor plan including sound sources and the user position, is described. Techniques are presented by which the user can "walk-through" the virtual workroom arbitrarily, experiencing the predicted noise visually and aurally, updated in real-time, as well as interact with the simulation - for example, to introduce noise-control measures -and visualize and auralize the resulting noise. An example of noise control involving sound-absorptive surface treatments and source enclosure is presented.
