Interesting you should ask. https://www.youtube.com/watch?v=z58RORCUTao https://www.youtube.com/watch?v=z58RORCUTao

  “Silent” is a stretch, though it doesn’t seem too bad: https://youtube.com/shorts/W_WDw1KFHUg https://youtube.com/shorts/W_WDw1KFHUg

    They're quiet enough that if you're anywhere near a road you won't hear them over the noise of car tyres. In the video you linked the sound of the parachute deploying was significantly louder than the drone itself, that's close enough to silent for me.

      Yeah but cars are too loud. It's not good enough to say "don't worry they'll be drowned out by the biggest source of noise pollution there is". I suppose the future is everyone inside sound proofed bubbles because outside will be hell.

      I live in the center of a big city, but my windows are pointed away from the road. At the moment I am hearing someone one building over three floors down practicing piano, and the startup devs opposite chatting over a cigarette on the fire escape. Might be "close enough to silent" for you, but cars are really loud. If this is in even the same league, this is too loud, especially as you just can't get a flat with windows pointed away from the drones.

        I suggest you actually watch the video linked above, it gives a really good idea of how quiet it is.

        This is HN, so I think I can be pedantic without reservation here. In Rober's video the drone is not any less loud, it's just that the power in each frequency is smoothed out. In that, the total power is the same, just now more evenly distributed. We humans then perceive this as more quiet. The drone is essentially more akin to a white noise machine than a machine that buzzes in certain frequency bands. For the curious, Tom Scott talks about the oddities of human hearing here : https://www.youtube.com/watch?v=Is_wu0VRIqQ https://www.youtube.com/watch?v=Is_wu0VRIqQ TLDR: Human hearing is more 'sensitive' to certain frequencies, perceiving them as louder despite being the same power.

        There is also a short posted below that which shows the drone in action. Seriously watch it, it's 10 seconds long and you can hear how quiet it is with no other sounds around.
