Answer :

IT DOESN’T TO ME EITHER :D:D:D:D I’m glad someone’s finally brought this up. I’d love to see a UV detector, like different shades. Filter out the known stars and see what else is giving off light. Or as stupid as it sounds a smell-o-scope (yes… futurama) but it’s not that stupid really. I mean like you said, their signals might be completely different. The chances of us finding anything via sound is just stupendously low. Not to mention the fact we have to scan all of space in our tiny little microscopic frame of time. And then even if we did find something and it was say 3 million light years away, then anything we’re detecting now happened 3 million years ago!
