You're correct, but I'm also curious how you could measure accuracy here. There isn't any easy way that I can think of.

That's not an unreasonable question, however the larger point is that this sort of thing cannot be done perfectly accurately.

This was established mathematically, answering an old 1966 question from famous mathematician Mark Kac: "You can't hear the shape of a drum" -- there isn't a unique answer even when allowed to use arbitrary test sounds.

If you can't measure the results then the entire thing needs a rethink.
