    Okay, so we've all seen the optical illusions... but have you guys ever heard of auditory illusions?

    I was procrastinating the other day and came across this...

    listen to it the first time while watching what he's saying... then afterwards, replay it, but close your eyes and listen.

    The Exploratorium here in SF has an exhibition going on called Listen: Making Sense of Sound, and they have displays on the McGurk effect and a variety of other interesting (to science dorks like me, at least) audio phenomena. Cool stuff.

    That is one *bad* sheep impersonation.

    All I hear is bah-bah. I think it might be due to the low quality of youtube and the lag between audio and video.

    With Visual input, it sounds distinctly like "DA DA"

    If you watch and listen, he's saying, "DA DA DA DA DA DA"; if you you just listen, he's saying, "BA BA BA BA BA BA". You see a mouth making a Duh shape and your brain draws the wrong conclusion ...

    Cool.

    Edit: Beat me to it!

    my girlfriend thought i was nuts when i showed this to her. She said that she didn't hear the da part very well. But, she has horrible vision (maybe that's why she's going out with me?) so maybe she's used to not watching what people are saying...

    hayduke, ucfgrad93, and Fearless Leader... you guys don't wear glasses by any chance, do you?

    Good trick... but I could kinda tell he wasn't saying GA GA while I watched... but when I closed my eyes it made it much more prominent that he was saying BA BA

    Hmm, like some others I just heard "ba ba" without reading anything and while looking at the guy. I have very good vision.

    Pretty cool.

    For those who don't get it, try hearing it with your eyes closed, and then mute the computer and watch it again.

    I heard "BA-BA"

    I really don't understand this. How does one hear "GA-GA"??:confused:

    You don't hear it. Mute the computer and read lips.

    right, what's supposed to happen here is... when one's mouth lips "ga ga", while "ba ba" is dubbed over, to an observer it should sound like "da da".

    However, when one doesn't watch the mouth moving, and just hears what is being dubbed, he or she should be able to hear "ba ba"

    I guess this doesn't work for everyone, but for those that is does work for, it's pretty neat.

    On the third listen it sounded like "You are the angle of death. The time of cleansing is now at hand".

    Is that just me?

    Probably the same people that found out that the Dark Side of the Moon synced up to the Wizard of Oz...

    Yes, but It's mainly cookery recipes and Cricket scores.
