There is no known medical or surgical treatment that will restore hearing in sensorineural hearing impairment. Treatment consists of rehabilitation through the use of hearing aids and special training. Children with profound sensorineural hearing loss can be treated with a cochlear implant.
Location: Lovund, Nordland, Norway. Meteors become incandescent â or glow â almost as soon as they hit Earthâs atmosphere. Some meteors, such as the Perseids in August, burn up in the atmosphere at about 100 kilometers â or 60 miles â above Earthâs surface. Other meteors, such as the Draconids in October, fall to 70 kilometers â or about 40 miles â before they heat up enough to glow and vaporize. The difference is that the Draconids are much slower meteors than the Perseids. So the height in the atmosphere at which a meteor begins to glow depends on its arrival speed.
Most meteors are composed of debris left behind by comets as they orbit the Sun. A meteor shower occurs when the Earth intersects a comet's path and moves through the stream of debris and dust emitted by the comet. The meteors in a shower appear to originate from one area of the sky called the radiant.eteoroids the size of a fist or larger may survive the trip through the atmosphere to land on the Earth's surface. They are then known as meteorites. A meteorite located after a witnessed descent is called a fall. A meteorite from an unwitnessed descent is called a find.
