Early Hearing Detection and Intervention (EHDI) refers to the practice of screening every newborn for hearing loss prior to hospital discharge. Infants not passing the screening receive diagnostic evaluation before three months of age and, when necessary, are enrolled in early intervention programs by six months of age.
The different treatment methods are Hearing aids, Cochlear implants, Assistive devices, Wireless devices, Classroom. Hearing aids are devices that work to improve the hearing and speech comprehension of those with hearing loss. It works by magnifying the sound vibrations in the ear so that one can understand what is being said around them. The use of this technological device may or may not have an effect on one's sociability. Some people feel as if they cannot live without one because they say it is the only thing that keeps them engaged with the public. Others dislike hearing aids very much because they feel wearing them is embarrassing or weird. Due to their low-esteem, they avoid hearing aid usage altogether and would rather remain quiet and to themselves in a social environment. Cochlear implants improve outcomes in people with hearing loss in either one or both ears. They work by artificial stimulation of the cochlear nerve by providing an electric impulse substitution for the firing of hair cells. They are expensive, and require programming along with extensive training for effectiveness. People with cochlear implants are at a higher risk for bacterial meningitis. Thus, meningitis vaccination is recommended.
Globally hearing loss affects about 10% of the population to some degree. It caused moderate to severe disability in 124.2 million people as of 2004 (107.9 million of whom are in low and middle income countries). Of these 65 million acquired the condition during childhood. Hearing loss increases with age. In those between 20 and 35 rates of hearing loss are 3% while in those 44 to 55 it is 11% and in those 65 to 85 it is 43%.
