    There’s a similar effect that happens at 2:34. I just stopped hearing what he was talking about till about the 2:38 mark.

    Maybe he was just boring you?

    I wonder if this still happens with abnormal psychologies, like with schizophrenics.

    Reminds me of several other tricks that can be played on the brain that Daniel Dennett talks about in some of his writings on nueroscience. Just another observation that puts into question how much human beings can really “know” or how much “true” information is transferred from the exterior world into our brains vs. the brain just making a pattern because it needs to.

    The BBC’s excellent ‘Horizon’ documentaries [from which this small clip was taken] are some of the best presented on TV. In this case popular science with the complete background information. For those who live in the US and do not have access to them, many are available on YouTube, as is “Seeing Is Believing” [in 6 parts].

    If you close your eyes or turn away from the screen when they start with the Ba Ba Ba / Fa Fa Fa sequence, then you can clearly hear only one sound: Ba Ba Ba.

    Does this mean that blind people have perfect hearing, or does the lack of eyesight “conflicts” just make them better as hearing? Does the telephone therefor transfer “perfect” message?

    Maybe the eyes are allowed a higher priority when the input comes in. :)

    Oops, meant to say “better AT hearing”…

    I watched the programme when it originally aired on the BBC. Fascinating stuff – quite discomfiting to know that our senses can not always be relied on – they can be ‘tricked’, they edit stuff out, and they fill in the blanks when there’s not enough to provide a whole picture … and they can be adapted/expanded to work in ways previously never thought possible.

    Why ba? Does it work for the other vowel sounds?
