The da Vinci propeller was, in fact, a bit noisier than the loop propeller at any given rotation speed. But the aerial screw also produced more lift—the upward force that opposes gravity's downward pull. The researchers also knew that the amount of lift needed to remain fixed for common drone assignments such as delivering packages, so they then calculated the noise emitted by the da Vinci and loop propellers when producing the same amount of lift.
