This more of an audio experiment that I heard about from two different sources. You need headphones for this to work.
First listen to this
Did you understand it?
Now listen to this.
This was a short reading spliced up and every alternate bit was sent to one ear and the other bits to the other ear. So in the first sound we are hearing what the ear is hearing; sounds, whistles and cuts. First through one ear then the other. In the second pieces the sounds are put together. Now here’s the interesting bit. Each ear is hearing meaningless sounds. But if they are played together in sequence we make sense of them. that means that the brain is arranging these sounds together and making sense of them!
I first heard Israel Rosenfield talk about this at the Memory Marathon (Listen around the 9:00 mark.) Then I read in Roger Scruton’s Understanding Musics that a researcher called Diana Deutsch did a similar experiment in music. Basically it’s our brains that make sense of all the auditory data and give it meaning. Much to think about here.
