A drone whine is high(er) pitched, so it doesn't go through closed windows and doors nearly as much, and the noise is a relatively short range and not supersonic like a helicopter rotor. Diesel truck rumble is low pitched and pretty much goes through everything, closed or not.
And the human perception of higher pitched noises is that they're much more noticeable and much more obnoxious. And when the kid across the street is flying his drone, I can hear it in my living room through my double-paned window. I'd much rather hear the FedEx truck idling than that fucking thing whizzing around - and it's hundreds of feet away!
