Hearing Loss

Hearing impairment In the United States, about 32 million people are decreasing their hearing. In this figure, about 2 million people have severe hearing loss that is sufficient to be considered as paralyzed. We define the term "We" to be partially or completely absent (Lytle & Rovins). Throughout history, many technical advances and mainstreaming to help Deaf people such as Deaf people, sign language, hearing aids and cochlear implants have been invented.

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

Sensory hearing loss is caused by dysfunction of the inner ear, cochlea or nerve, which transfers pulses from the cochlea to the auditory center in the brain. The most common cause of sensorineural hearing loss is injury of cochlear hair cells. By definition, it can be estimated that more than 50% of the population over the age of 70 has hearing impairment. This is not actual hearing loss, but it can cause serious deafness. One hearing treatment disorder is King Kopeckitski syndrome, which is characterized by being unable to process background noise in noisy environments despite the usual performance in traditional hearing tests. Hearing disorders are sometimes associated with speech disorders of people of all ages
