How do you hear?
Your ears enable you to detect vibrations in the air around you. We call these vibrations 'sound'. You can hear a huge range of sounds, from a deep bass to a high– pitched whistle, and from a tiny whisper to a loud rock band. Sound travels through your ear and reaches the special receptor cells right inside your inner ear. These cells change the sound vibrations into electrical signals, which pass along the auditory nerve to the brain.
Do you have perfect pitch?
When you listen to music, most activity is in the right side of your brain. But in 1995, scientists identified an area in the left side of the brain that is enlarged in people with exceptional musical ability. This was especially true of people who have 'perfect pitch' – the ability to identify any musical note without having to compare it with any others. Scientists think that perfect pitch has a genetic basis.
