The two major causes of deafness may be the genetic or environmental factors, although between 20 and 30 per cent of cases of hearing loss are unknown.
Children may be suffering deafness of middle ear infections that were not treated well or time, or after a meningitis, and in adults is often caused by exposure to noise, ototoxic drugs at a very hard blow, or simply the aging process.
It also influences the inheritance and, curiously, the race. Whites suffer more hearing loss than blacks, and the incidence is higher in urban than in rural areas.
When there is an injury to the inner ear or the auditory nerve, hearing loss is permanent. Sometimes the sound can not reach inner ear wax or fluid buildup, or a punctured eardrum.
The key is to understand that hearing problems that are not addressed, they often worsen. The impairment has an important impact on the emotional health of those who suffer, because it affects your relationship with others and the world around them. That’s why many patients feel depressed when they stop to hear well.
There are hearing aids, digital and wireless is the first that mimics the human ear, and in fact was designed to simulate how the two ears and brain work together to process sound.
You need two eyes to perceive the distance, with the ears it is the same, it requires the information they receive two to really listen. The device enables interaction with others, but also electronic devices that were previously banned for these people.
The devices are manufactured so they are almost invisible. This can be used in cases of mild hearing loss, moderate or severe.
