Or do they just hear it as noise, not as a tune or melody?

Or don't they hear it at all? Just as vibrations?

For example; could there be another world with life that breathe something other than oxygen? Like a different element of sort. Or could there be something similar but not exactly water that could support life? After all, our corner of the universe is extremely small compared to the entire picture. I'm just curious if there are other elements unknown to man. I also have wondered if there is another element besides Oxygen that would keep us alive.
