A cursory google search has birds at around 30db and a DJI drone at around 1000x louder at 70db. I think this is something that can be worked on and improved. Also, I'd love to hunt duck one of these days, sounds like a very unique experience!

- grogenaut 6y agoI specifically mentioned hovering not flying. We have a humming bird feeder right above a table, them suckers buzz us a lot. 50db my dishwasher is 48db (measured). Humming birds significantly louder when hovering. Drones are always hovering currently. Yes they can likely get a lot quieter. Planes are still quite loud, they've had 100+ years of work? Birds, they still make noise, and they've had millions. They seem to switch modes of flight to be quiet.
- daxaxelrod 6y agoJust to clarify, you measured hummingbirds at 50db? Birds had millions of years to optimize for lower energy consumption which makes me wonder if it could be mechanized. I understand where you're coming from with the plane analogy. I'd argue that a lot has been done to cabin acoustics the demand is that its quieter while you're on a flight. The desired for quieter drones stems more from 3rd parties.
