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.
Meteor Showers are named for the constellation out of which they seem to come. Because all of the particles are moving in roughly the same direction, the meteors which strike our atmosphere all âpointâ back to the direction of the cometâs path. This point in the sky is called the Meteor Shower Radiant. The Perseids appear to come from a point next to the constellation of Perseus. Perseids can be seen anywhere in the sky, but the direction of motion, when traced back, will point to a point next to the Perseus constellation.
