No Sport, The snoring of a stalled prop is very typical, and not at all like the sound of high tip speeds.
You are right in that the stalling is rpm depending, and that it does not occur over the whole blade length. I.e., an 8x8 prop is square at the tips, but oversquare at the inner diameters IF the prop has true pitch over the blade length. Lots of room here to play with prop design.
