Anyone here know about the mythology of sound/noise/silence?

I've been looking for information on any legends about something that could take away someone's voice in one way or another and all I can find is a Buffy episode of all things! I did find one thing, the legend of Echo, and I'm thinking if I can do a play on that, but if there's anyone here who knows anything else that might be of use to me, that'd be great! Thanks!
