WHY DEAFNESS CAUSES
Deaf people usually have little to no hearing. Hearing loss may be caused by a number of factors, including: genetics, ageing, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins. A common condition that results in hearing loss is chronic ear infections.
*HOW WE CAN HEAR*
The ear is made up of three different parts: the outer ear, the middle ear, and the inner ear. These parts work together so you can hear. The outer ear, or pinna (the part you can see), picks up sound waves that then travel through the ear canal.
When the sound waves hit the eardrum in the middle ear, the eardrum starts to vibrate. When the eardrum vibrates, it moves three tiny bones in your ear. These bones are called the hammer (or malleus), anvil (or incus), and stirrup (or stapes). They help sound move along on its journey into the inner ear.
The vibrations then travel to the cochlea, part of the inner ear. The cochlea looks like a tiny snail shell. It is filled with liquid and lined with tiny hairs. The sound vibrations make the tiny hairs move. There are two types of hair cells: the outer and inner cells. The outer hair cells take the sound information, make it louder and tune it. The inner hair cells change the sound waves into electrical signals. The hearing nerve then sends the signals to the brain, letting you hear
The most common cause of acquired hearing loss is noise, which accounts for over one quarter of people affected by hearing loss. You can protect your hearing by reducing your exposure to loud noise or wearing suitable protection such as ear muffs or ear plugs.
