My guess is, and do correct me if I'm wrong, what you're looking for is how to put the energy of sound into a spell. If sound energy can shatter glass, I'm quite sure it can be put to good use. People across many cultures use bells in their places of worship for a good reason.
Having said that, ancient spells in extinct languages have a vibe because they were created and perhaps even practiced by people in a time when these languages were like second nature to man. So, again, this is a just a personal point of view, I believe that if you perform a spell using a language, then pick a language you're most comfortable with, because it's important to understand something to believe in it. And if you believe in what you're doing then the spells seems to work better... Just my pov.
