On the upside they're not quadcopters, the noise from dozens or hundreds of those flying by daily would drive people completely insane.

- 8note 4y agoNo more than the thousands of cars, I imagine Cars and trucks are really loud
- Aperocky 4y agoquadcopters are pretty quiet if they are flying at a good distance, it's only the ones zooming in that are loud. Just be as far away as you'd like an actual highway, but in this case vertical space works too.
- saint_abroad 4y agoSound decreases by 6dB for every doubling of distance: https://www.airbornedrones.co/drone-noise-levels/ https://www.airbornedrones.co/drone-noise-levels/ So a typical 80db commercial drone flying at 300m (CAA minimum) would be 50db at ground level (closest point), or about a loud conversation (but less than quiet road traffic).
- Aperocky 4y agodrones noise are very directed, the side noises are much smaller than if directly below. Source: I did drone noise research a few years ago. It's almost impossible to detect via noise with decent distance (>100m) unless directly under.
