New technical paper available: Applying Turbulent Flow Cross-Correlation Function to an SEA Side Glass for Windnoise

Last week, my latest technical paper was published at the ISNVH (International Styrian Noise, Vibration & Harshness Congress) congress in Graz, Austria.

This paper presents new advances in predicting wind noise contribution to interior SPL in the framework of the Wind Noise German Working Group composed of Audi, Daimler, Porsche and VW.  In particular, a new approach was developed that allows to fully describe the wind noise source using CFD generated surface pressure distribution and its cross-correlation function and apply this source on an SEA side glass.  This new method removes the need to use a diffuse acoustic field or several plane waves with various incidence angle to approximate the correct acoustics source character to apply on the SEA side glass.  This new approach results are compared with results previously published which use more deterministic methods to represent the side glass and the interior of a vehicle. This paper was a collaboration between Luca Alimonti, Anton Golota and myself.
