Towards the auralization of electrical machines in complex virtual scenarios

In industrial work environments electrical machines are used in various applications and are often perceived as annoying acoustic sources. Their auralization in realistic environments allows to assess the sound quality and to develop acoustically optimized machine designs and controls. Virtual reality combining 3-D visualization and binaural sound reproduction enables designer and user to fully immerge into the application scenario. Efficient computation of the radiated sound field at arbitrary torque/speed points is required. This work proposes a general concept for fast auralization interfacing electromagnetic force excitation, structural-dynamic response, radiation patterns and binaural perception.
