I saw last week that Lockheed has announced the release of a new quadcopter called Indago VTOL Quad Rotor.

They've got price sheets posted. It seems overpriced but what I found interesting in the specs is how quiet it is.
Whisper Quiet - 62dB at 3m, 52dB at 10m
At 10m distance, the acoustic signature of the Indago is comparable to the hum of a refrigerator.
I own a Vision+ and it's loud. Are there aftermarket props that are quieter?
