TAURA: Traffic Noise Auralisator
The videos on the right show auralisations which were generated with our calculation model.
Accelerating passenger cars
For accelerating passenger cars an emission synthesiser was established. It separately generates tyre/road sound and propulsion sound using spectral modeling synthesis. The characteristics of the propulsion sound depend on the instantaneous engine speed, engine load and emission angle. The steering parameters of the synthesiser were obtained from measurements on a chassis dynamometer. To produce realistic auralisations, the driving dynamics are simulated and used as input for the synthesiser.
