Real-Time Capable Wind and Rolling Noise Synthesis for a More Realistic Vehicle Simulator Experience 2020-01-1546
Nowadays a large proportion of the overall acoustic vehicle development takes place within virtual phases. Increasingly, projects require the auralization of virtual developed acoustics measures, e.g. from the disciplines of electro-acoustic, ride comfort, rolling noise or passive acoustic on dynamic or static driving simulators. In practice it turns out that in addition to engine noise also a realistic reproduction of rolling and wind noise is important. In this article, approaches to synthetic rolling and wind noise generators are discussed. We developed such real-time capable sound generators that are parametrizable according to arbitrary driving conditions. Furthermore, spacial reproduction of the driving sounds is achieved for binaural headphone, as well as for other arbitrary loudspeaker setups, like often found in driving simulators. Derived models and parametrization are based on measurements and recordings from several real vehicles. In order to facilitate the adjustment on specific vehicles and designing rolls thereof, the suggested parametrization is guided by a defined procedure. The influence of these noise components on an improved perception of the overall driving experience is objectified by means of a jury evaluation and presented here.
