Aerodynamics & Aeroacoustics

Conclusions will be presented first to accommodate readers with limited time. For those interested in a deeper dive, the following sections provide background on aeroacoustics and a detailed explanation of the data collection process.

Conclusions

On-road testing effectively identified trends among the evaluated anti-buffeting devices, demonstrating that a commercially available solution, as shown above, successfully reduces interior cabin buffeting in a 2019 Porsche GT3 RS.

To achieve more controlled and precise evaluations, future testing should incorporate wind tunnel experiments and/or computational fluid dynamics (CFD). These methods offer a stable environment and can provide deeper insights into the flow physics affecting the dBA results.
