Barber's Shop Illusion

After exploring much about music, I have decided to look more into the amazing and mysterious world of SOUND.

The definition of sound is: a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations.
This is the physical, and rather boring, definition. I want to explore what effect does sound have on us humans. I started by Looking at auditory illusions and how they can help us understand the workings of the human brain.The most exciting one I have experienced so far is 'the Barber's Shop Illusion'.

In order for this to work you'll need headphones. Make sure there is no noise around, close your eyes, turn the volume up a little bit, hold and press headphone on your ears for better hearing, play it and enjoy this impressive illusion.



The Barber's Shop Illusion is a demonstration of the stereo effect. Listening to it, you feel as though you are in a barber's chair, with the barber moving around you, clipping away at your hair. As the barber "moves" to your right, the volume increases slightly in the right channel and decreases in the left. Similarly, increases in the volume of sound from the clippers give the impression that he is bringing them closer and closer to each ear. The illusion demonstrates our ability to locate sounds in space; by comparing the inputs to the two ears, we can work out where a sound is coming from.

Looking into this, and other illusions made me want to learn more about sound. sound journey begins, Hope I won't be disappointed...
