They fly high enough that the noise is barely above background levels.
- OnlineGladiator 7y agoThat's doubtful. I can hear drones buzzing when they're over 500 feet away, and they're loud enough to be annoying (and those aren't carrying payloads so they are significantly lighter). Are they really using hundreds of feet of cable to drop the packages?
- Filligree 7y agoI think this varies significantly depending on drone design. You absolutely can make them quieter, you just have to compromise elsewhere -- for example, using larger props. This is a large drone to begin with, so that shouldn't be an issue. It's also got wings, so it shouldn't need to spin its engines at full except when it's hovering for a delivery.
- OnlineGladiator 7y agoI agree with some of what you said, but this is likely to weigh at least 10x as much as the drones I'm talking about when you include a payload of even a few pounds. There is another comment on here from someone in the trial city talking about how the residents complain about the noise. You can't beat physics.
- djhn 7y agoI was worried about this too. I recently got a newest gen DJI drone, and was self conscious about flying it for this very reason. Turns out, with the quiet propellers installed it disappears into the urban background hum when it's 30m up in the air. I've also flown it in uninhabited wilderness (national park, two days hike to nearest anything) and even there it's about 80-100. Add any horizontal distance and you will find it very hard to locate the drone after looking down at the controller (at least until you get better at flying it and develop better spatial awareness).
