As you can cheat your own ears

Ears lie brain no less than glaza



Diana Deutsch been studying memory and music therapy, especially those where people have taken the perfect pitch. She also worked on the auditory hallucinations: via the ears, you can trick the brain as well as via the eye. The difference is only one - in the case of the eyes, we quickly raspoznaёm deception.

Some identified Deutsch auditory illusion many of us are familiar. For example, you are still a few people hear the music coming from the other room. Some hear the notes rise, others - as a decrease. Two people hear the melody in different ways, because the melody tone is ambiguous.



The bottom line is that the melody is made up of two series presented tones that differ from each other by half an octave (the interval known as Triton). Sheet music in clearly defined, but it is impossible to make out an octave - one and the same note in different octaves sounds differently, and hence there is an illusion.

There are also more common illusions that are common in everyday life, but we do not notice them. The key to most of them is the illusion of an octave, it also Deutsch illusion: if sounds are played alternately in one ear or the other, it knocks the brain confused.

For example, imagine a man in headphones: in one ear, the music plays a note an octave higher, in the other - an octave lower. The man thus can not switch between the ears although he hears different sounds in each ear, he feels that he is in both ears hear the same sound.



Another example - the scale illusions Deutsch. To listen you'll need headphones. In the first part of the video sound simultaneously ascending and descending notes for each ear the. In one of the headphones connected melody periodically replaced by a cacophony, but your brain mixes the sounds coming from the left and right ear, together and you finally hear something different from what is actually played.

And finally, the illusion of phantom words: two speakers playing two sounds, they alternate left and right speakers, and those sounds vaguely reminiscent of the words. After listening to quite some people really begin to distinguish between the sounds of words - usually in their own language, whatever it was.
