If you ask me, that makes something one hears as a result of placebo audible. Does that necessarily make it a real sound? No - because the definition of audible is tied to what you hear, not more specifically to what sounds occur that one may hear.
For example, with the McGurk effect I would say that when the presenter is shown saying "bah" but his lips move like "fah", "fah" is audible when you are watching him - and when you close your eyes, "bah" is now audible. I would say that audibility is intrinsically tied into what we perceive, and as such does in fact incorporate the rest of our senses - even when they mislead us.
But we're playing word games again - because based on context it is perfectly clear what he meant.
