How do owl feathers work?

An owl’s primary feathers are serrated like a comb. This design breaks down turbulence into smaller currents called micro-turbulences. Then the edge of the feather muffles the sound of air flowing over the wing and shifts the angle at which air flows. These soft feathers allow air to pass through which eliminates sound.
