This is a reduced ability to hear sounds in the same way as other people. This occurs when a person cannot understand speech through hearing, even when sound is amplified. This refers to a total lack of hearing. An individual with profound deafness is unable to detect sound at all. The severity of hearing impairment is categorized by how much louder volumes need to be set at before they can detect a sound.
Some people define profoundly deaf and totally deaf in the same way, while others say that a diagnosis of profound deafness is the end of the hearing spectrum. How does hearing work? Sound waves enter the ear, move down the ear or auditory canal, and hit the eardrum, which vibrates.
The vibrations from the eardrum pass to three bones known as the ossicles in the middle ear. These ossicles amplify the vibrations, which are then picked up by small hair-like cells in the cochlea.
These move as the vibrations hit them, and the movement data is sent through the auditory nerve to the brain. The brain processes the data, which a person with functional hearing will interpret as sound. Types There are three different types of hearing loss: This type can occur for many reasons, including: The ossicles may become impaired as a result of infection, trauma, or fusing together in a condition known as ankylosis.
This kind of hearing loss is normally due to damaged hair cells in the cochlea.
As humans grow older, hair cells lose some of their function, and hearing deteriorates. Long-term exposure to loud noises, especially high-frequency sounds, is another common reason for hair cell damage. Damaged hair cells cannot be replaced. Currently, research is looking into using stem cells to grow new hair cells.
Sensorineural total deafness may occur as a result of congenital deformities, inner ear infections, or head trauma. Long-term ear infections can damage both the eardrum and the ossicles. Sometimes, surgical intervention may restore hearing, but it is not always effective.
Deafness and speech Hearing loss can affect speech ability depending on when it occurs. Prelingual deafness This is an inability to fully or partially hear before learning how to utter or understand speech. An individual with prelingual deafness was born with a congenital deformity or will have lost hearing during infancy.
In the majority of cases, people with prelingual deafness have hearing parents and siblings. Many are also born into families who did not already know sign language. They consequently also tend to have slow language development.
The few who were born into signing families tend not to face delays in language development. If children with prelingual deafness are given cochlear implants before the age of 4 years, they can acquire oral language successfully. Oral language and the ability to use social cues are very closely interrelated.
That is why children with hearing loss, especially those with severe symptoms, may not only experience delayed language development, but also slower social development.Just as "deaf-mute" and "deaf and dumb" are inappropriate labels, "hearing impaired" is an outdated way to collectively label people with any level of hearing loss.
It does not account for cultural identity. Elderly people with a hearing loss developed late in life often refer to themselves as being hearing impaired. To Call Illinois Relay simply Dial Relay is available 24 hours a day, 7 days a week, days a year!
