After all, sound is his portal into your mind. I recall him saying that every weapon has its own sound. I don't recall him saying anything about anything else, though.

I actually might go through and listen to various moments of characters' using their Semblances to see if they do it every time.

I know that Weiss and Pyrrha's Semblances do make their own noises. Weiss' is a high sweee noise, while Pyrrha's is a low woom.
