You are right that this thing is going to be noisy as hell. I can say this without having heard it because basic physics makes hovering craft with little propellers impossible to make quiet. Welcome to the new world of a flying buzzsaw delivering your neighbor's toothpaste at 7 AM.
No wonder they chose to play classical music over this video.
If I’m working on a drone in my yard, surrounded by buildings, the noise has a direct line to a few people. If I put that drone at 200 feet, suddenly many more people are directly exposed to that noise. Imagine how loud a UPS truck would be within a 90° cone above your bedroom. Also, consider how many more people would be affected by that noise per delivery.
But to be fair, the frequencies are quite different.
The UPS truck that delivers to my block makes a bit more noise then the average car driving down my street, parks, the driver gets out of it, and spends a couple of minutes making >20 deliveries. A human carrying cardboard boxes does not make much noise. Neither does a powered-off truck... And it's not like UPS does domestic deliveries from the back of 20-wheeler rigs.
This is orders of magnitude less noise than 20 drones, coming and going, throughout the day. (Not to mention the ones passing overhead, to deliver to the next block down...)
Yeah, but if I have enough money/income (which is a big caveat, I know) then I can have some control over the location of the UPS truck by virtue of living someplace not too close to a road.
When was the last time a UPS truck drove over your house / apartment / etc?
