Which aerodynamic consequence results when barn owl feathers exhibit asymmetric barbule structure?

💡 Explanation

When barn owl feathers have asymmetric barbules, it facilitates turbulence diffusion because tiny structures disrupt airflow, diminishing pressure fluctuations, leading to quieter flight for prey detection. Therefore reduced noise results, rather than enabling low speeds, high lift, or maneuverability; each of which require different feather structures.
