I'm not sure how you were doing it, but when I think of "hum", I think of making a noise with my mouth closed. I found opening my mouth and making a tone worked much better. I'm not sure how many people think of hum the same way. I've noticed lately some words being used slightly differently than I am used to (the one coming to mind right now is "giggle" in a story that in context I would interpret as meaning "chuckle"), and at this point it's happening enough that I'm not sure if there's a shift in perception of these words or if I just always interpreted them more narrowly than they were intended.
