I once did a blind (rather than double blind) test with a friend where we did this; the person playing them knew which was which but the listener didn't. We could both tell 128kbps from the original but not 160kbps or above.

You could try this test here, though you have to email them to get the answers:

LOL - if you want to talk scientific - use science and you would already know the answer to your question!
