Were it funky stuff such as Aburame which requires doing it from birth, I'd get that. Sound however, I do not.
I mean, think about it dood. Clap yo hands, and poof, you have sound. Speak or shout, there you go again. Hell, the latter of those two is an age old move of mine, an amplified shout; stick a bit of chakra to the vocal cords to reinforce/boost them, and let out a good roar, its that simple.
I don't mean to sound like an ass or anything, but being perfectly honest you claiming sound completely in this manner would be rather silly o^o it'd be basically the same as condemning everyone outside of the listed users into being so ungodly stupid they're unable to speak or even use their ears.
If you really want there to be an "element" about it on SL, I suggest you leave it to only the truly special stuff such as
Chakra Enhancing Music.
