Sound in videos is rarely recorded on location. What you hear when you're watching probably bares no relation to the real world at all. Also, it may be fine when there's one of them. When there's 50 coming and going from a popular tourist spot it'd be a very different story.

It sounds pretty noisy to me in that video, even with the music partially covering it.

It’s hard to say if it’s noisier than a car, but I wouldn’t say it’s quiet at all.

Being within ~10x the noise of a car is pretty quiet, considering they'll be up in the air most of the time. Unless the video is really misleading about noise, this won't be an insane nuisance.

It's definitely going to be noisier than a car because of the propeller noise. Small aircraft don't generally have mufflers on their engines, so a gasoline powered aircraft will have both propeller noise and engine noise that are greater than that of a modern automobile (imagine your car without a muffler or even much of an exhaust pipe - no, not you Tesla owners).

The video specifically mentions that they are fully electric. It isn't a gasoline powered aircraft.

Yes ... my point was that it was going to be quieter than a gasoline powered airplane and noisier than a car. As an aside, I suspect the "buzzing" noise made by the propellers was attenuated in the video post production.

If it has the same noise profile as a current consumer camera zone, I want none of these things anywhere near me.

When flying horizontally, I can imagine it is quite quiet.

While taking off and landing, I expect it to be very noisy and cause a lot of wind.

With work, the landing and takeoff could be very fast - maybe just a couple of seconds until it starts to get up to speed and can use the quiet wings rather than noisy tiny propellers.
