Am I correct to assume that most of the noise is coming from there being an increased amount of air turbulence coming off the prop blades than their would be were the drone (and thus it's props) less heavily loaded?
- outworlder 6y agoSmall and light drones are still very noisy. It is not as bad when it's in a steady state, but any maneuvering increases noise by a lot. We have replaced moving parts (as in helicopter swashplates) with fixed, but quick to react motors, spinning at a very high speed. Those generate lots of turbulence whenever they need to shift speeds for maneuvers. There's someone in this thread saying that their F150 is less noisy than a drone. That is unlikely to be true, but the emitted frequencies are very different. A high pitch whine is, for whatever reason, very noticeable, compared to a lower pitch of similar amplitude. Think dentist drills.
