Multirotor noise level

[jackwrangham]

Anyone have any noise-level (decibel) readings to hand for a hexa multirotor, similar to skyjib 6?

Cheers

No. But, I can tell you quiet multis are made of big props turned slowly.. Makes a world of difference.

So true. I have 11 and 12 inch Graupners that are extremely quiet. You can't hear it at altitude.

I'm turning 10 or 11" props at around 5600 RPM and I'm glad I can hear them. I might lose it if I couldn't.
