Random idea: what if semblance sounds are not hearable to the human ear? Like, only certain animals and faunus with extra ears can catch them?

So Velvet brings up that right before Yang hit Mercury, she heard the same sound she heard before Yatsunashi was taken down. And that Coco told them that in that moment she saw fake!Yatsu.

While Blake should theorically have noticed this too, like any other faunus in the audience, she wouldn't be able to make the connection because she doesn't have access to Coco's testimony on the fake!Yatsu.
