On the other hand, our communications would clearly be so high as to be indecipherable by said black hole. Not to mention that the sound has been on its way for about a billion years the black hole that is producing it might have blown up already, and we are just waiting for the evidence of it to get here. Heck, it make take us with it.
I'm pretty impressed that those astronomers could measure pressure waves in space, which is a vacuum with therefore zero pressure. It must be a pretty powerful sound to be carried through a medium where molecules are a meter or more apart.
And black holes have such strong gravity that they suck back nearly everything they radiate, so this sound had to punch through that, too.
Like I said before, two black holes with nearly the same frequency could do some damage.
