Munich Aeroacoustics Identifies Fractal Vertipad Surfaces as Potential eVTOL Noise Reducers

Acoustic modeling by German consultancy Munich Aeroacoustics (MUAA) suggests that specially designed fractal surfaces on vertipads could reduce noise from electric vertical takeoff and landing (eVTOL) aircraft operations, especially at elevated sites like rooftop vertiports. Using their FLYO simulation software, MUAA compared eight hypothetical pad configurations against untreated surfaces

Results indicated noise exposure reductions of approximately 5 dB behind the pad and measurable effects up to 300 meters at elevated locations. However, MUAA and Skyportz emphasize the need for further laboratory and field testing to validate the panels’ actual acoustic performance
