From Neil Doherty
You report that auditory rivalry was discovered in 2006 in France (14 March, p 34) but this idea has been around for at least a decade.
In 1994, during an Open University tutorial at Durham University in the UK, my professor conducted an experiment showing that sounds could be heard in two different ways.
He played the class a recording and then asked us if we could differentiate between the two different sound repertoires contained in it. On his playing the recording again, I found that I could swap from one perception of the type of sound to another. I called it an “auricle illusion”.
