If you live anywhere where people love Harleys and Dodge Ram trucks with aftermarket exhausts, then 65 is luxury levels of quietness.

Also, whether in my small village or in a fancy suburb, there seems to always be someone with a 2 cycle, muffler-free piece of lawn equipment running. Leaf blowers are the worst, but weed trimmers and now even leaf vaccuums are common.

Or, if you live in an urban area, especially in NYC, there's rarely a moment that you don't hear an emergency vehicle siren echoing throughout the neighborhood.

Unfortunately, it's just a noisy world. At least this aircraft is electric and has some goal of keeping noise as low as possible.

They don't say how/where they measured, so the figures are basically worthless. 65-70 dB(A) seems on the low end of consumer unmanned quadcopters[1], e.g. "Maximum sound pressure level for fast flyover at 15 m height: 62 dB(A)" for a DJI Phantom 2 weighing less than 2kg.

If they managed to get into that range for a vehicle that must weigh many hundreds of times more, I guess that'd be very impressive.

Yes, except it will be on top of a building (most likely) and fly hundreds of feet above.

Lawnmowers are significantly louder.

I think a helicopter is a better comparison here, and they seem to be 80-100 dBA.

Significantly quieter than car traffic noise. Struggling to see the issue here.
