Zipline publishes modeled noise reductions from revised flight trajectories
Zipline says fleetwide sound-optimized dynamic flying, together with other hardware and software changes, reduced modeled per-flight sound exposure by 68% and peak volume by 24% against its 2025 fleet. It also claims lower energy use and shorter flights.

Using wind and a longer wing-borne segment could change a delivery aircraft's acoustic footprint without changing the delivery location.
The figures are from internal modeling rather than published independent ground measurements; request microphone geometry and comparable route conditions.
