The Difficulties of Hearing Loss in Education

People in the list below have something in common: Whoopi Goldberg, Pete Townshend (Who's lead guitarist), Huey Lewis, Helen Keller, Ludwig Van Beethoven and Thomas Edison. If you can not guess, all of these people have hearing loss. In terms of formal definition, hearing loss is "a set of diseases that cause disruption or distortion of auditory information that the central nervous system is reaching or is undergoing." Hearing impairment affects not only adults but also adults, and it is also common among children.

There are four main types of hearing loss. Conductive hearing loss, sensory deafness, central deafness, and combination of conductive and sensory hearing loss known as mixed hearing loss. Another problem that more and more people perceive is that hearing disorder is not itself deafness, but it is difficult to perceive sound. Conductive hearing loss occurs when the sound does not reach the inner ear (cochlea). This may be due to a malformation of the ear canal, dysfunction of the tympanic membrane or dysfunction of the middle ear. On the eardrum, defects ranging from small to large can be seen, resulting in various levels of hearing loss. Scar tissue after ear infection also causes tympanic dysfunction and retracts and adheres to the inner part of the middle ear

Hearing loss may be gradually or suddenly. Hearing loss is negligible, so conversation may become difficult or hearing loss may become serious. The rate at which hearing loss occurs may provide clues about the cause. If hearing loss occurs suddenly, it may be a problem of trauma or blood circulation. Stepwise seizures suggest other causes such as aging and tumor. If there are other related neurological problems such as tinnitus and dizziness, it may indicate that there is a problem with the ear or the brain. Hearing impairment may be unilateral or bilateral. Unilateral hearing loss is usually associated with electrical conduction, trauma, and acoustic neuroma. Ear canal infection, trauma and ear ache with accompanying ear canal obstruction
