"Supersonic" means a) faster than the speed of sound or b) (colloquial) ultrasonic, that is, too high to hear.

"Supersonics" with an "s" in the end means the study/technology of either.
The trope, however, is pretty clearly about just sound superpowers. Hence, it should not be described with the term "supersonic(s)". I'll see if I can fix the wording. It won't actually be changing the intended definition.

First paragraph of description before changes (emphasis added):
The power of supersonics. Able to shatter glass, crumble rocks, and knock down buildings. Er, in the world of fiction, anyways. Characters who have supersonic screams or other sound-based superpowers can usually do something like vocal mimicry, scream out sonic booms, and screech so loud it can paralyze people by making their eardrums bleed.

Seems fine for me.
"For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled." - Richard Feynman
Does this trope cover supersonic powers that aren't caused by your voice? For instance, a magical chime capable of shattering stone? If so, the name might be a bit misleading.
This Tropes namer is missing. The song "Make Me Wanna Shout". Add it and edit the article?
Is a sub trope to this - or is it an unwritten trope completely - that sound is represented in animation & drawing as round circles?
