We Hear All Types Of Sound In Our Brains---BY HARUN YAHYA

The hearing process also operates in a similar manner to the visual process. In other words, we hear sounds in our brains in the same way that we see the view of the outside world in our brains. The ear captures the sounds around us and delivers them to the middle ear. The middle ear amplifies the sound vibrations and delivers them to the inner ear. The inner ear transforms these sound vibrations into electric signals, on the basis of their frequency and intensity, and then transmits them to the brain. These messages in the brain are then sent to the hearing center where the sounds are interpreted. Therefore, the hearing process takes place in the hearing center in essentially the same way that the seeing process takes place in the seeing center.
The outer ear captures sound waves and delivers them to the middle ear. The middle ear amplifies these sounds and transmits them to the inner ear. The inner ear converts these sounds into electric signals on the basis of their intensity and frequency and then sends them to the brain.
Therefore, actual sounds do not exist outside our brains, even though there are physical vibrations we call sound waves. These sound waves are not transformed into sounds outside or inside our ears, but rather inside our brains. As the visual process is not performed by our eyes, neither do our ears perform the hearing process. For example, when you are having a chat with a friend, you observe the sight of your friend in your brain, and hear his or her voice in your brain. As the view in your brain is formed, you will have a deep feeling of three dimensions, and your friend's voice is also heard with a similar feeling of depth. For example, you could see your friend as being a long way from you, or sitting behind you; accordingly you feel his voice as if it is coming from him, from near you or from your back. However, your friend's voice is not far away or behind you. It is in your brain.
The extraordinariness about the real nature of the sound you hear is not limited to this. The brain is actually both lightproof and soundproof. Sound never in fact reaches the brain. Therefore, despite the volume of the sounds you hear, the interior of your brain is actually very quiet. However, you hear noise, such as voices, very clearly in your brain. They are so clear that a healthy person hears them without difficulties or distortions. You hear the symphony of an orchestra in your soundproof brain; you can hear all the sounds in a wide range of frequencies and decibel from the sounds of the leaves to the sounds of jet planes. When you go to a concert of your favorite singer, the deep and loud noise that fills the whole stadium is formed in the deep silence of your brain. When you sing by yourself loudly you hear the sound in your brain. However, if you were able to record the sound in your brain with a tape recorder at that moment, you would hear only silence. This is an extraordinary fact. The electrical signals that reach the brain are heard in your brain as sound, for example the sound of a concert in a stadium filled with people.
