Discovered by Diana Deutsch in 1973, the octave illusion is an auditory illusion produced by simultaneously playing two sequences of two notes that are spaced an octave apart, high to low, and low to high, in separate stereo channels over headphones. People who are right-handed tend to hear the higher pitch as being in their right ear while the results are mixed for left-handed people.
