I don't play an Au Ra myself, but I don't think that the Lore itself supports any of what you've listed. I seem to recall a statement that Au Ra don't have especially "better" hearing than the other races. I want to activate the Sounsyy flag right about now..
Unless you're not looking for Lore explanations. But if you're only interested in head-canon, the Lore forum is an odd place for this thread.
