If your child after wearing them for a reasonable time, has a and is , he/she may be
a candidate for a cochlear implant. At this writing, the desirability
of earlier implantation is being considered and some research
centers have begun implanting earlier.
A cochlear implant is an electronic device designed to provide
sound detection as well as improved speech understanding and
speech production. The cochlear implant is surgically implanted
in the ear. It bypasses the damaged parts of the ear and sends
electrical "sound" directly to the hearing nerve (the
auditory nerve). Research suggests that implantation during the
critical ages for speech and language development (between 2
and 5 years), is important for obtaining the best results. The
earlier a child can be implanted within this "window of
opportunity", the greater the likelihood that he/she will
make optimal use of a cochlear implant and achieve good speech
and hearing results. However, researchers are still not able
to predict how well an individual child will do following a cochlear
implant.
The surgery takes two to three hours and can be undertaken on
an outpatient basis or, at most, an overnight stay. The procedure
is covered by most insurance companies. For an eligible child
with a severe-to-profound hearing loss, cochlear implantation
can significantly improve a child's success with speech development
and listening but only if parents are highly motivated, and there
is a quality follow-up program available. The literature on cochlear
implants is extensive. Additionally, there are a number of informative
Web sites addressing all aspects of cochlear implantation.

All children with hearing
loss require some degree of educational and habilitative intervention.
Any level of loss can create challenges for a child, especially
in an academic environment. Even a child with a mild to moderate
loss-provided it goes undetected or untreated- has a higher likelihood
of repeating a grade than does a child with normal hearing.
A child with a mild loss may have subtle problems
which are not obvious either to parents or teachers. In fact,
in the past, mild hearing losses have generally been overlooked
as a significant factor in a child's speech and language development
or academic performance. Recent studies, however, debunk this
myth. A child with a mild loss will benefit from favorable acoustics,
hearing aids and/or a personal FM system. Soundfield amplification
may be helpful if the classroom is noisy or reverberant (echoes).
Favorable seating and lighting, as well as ongoing monitoring
of language and speech development, is important as well. Depending
on the level of loss, your child may benefit from speech-language
therapy and speechreading skills.
A child with a moderate hearing loss will benefit
from routine audiological evaluations and ongoing monitoring
of speech and language development, reading, and written language.
Amplification-hearing aids and assistive devices such as personal
FM systems-are imperative. Classroom acoustics should also be
addressed. A child with a moderate loss will benefit from speech-language
therapy to work on any language delays or difficulty in pronouncing
certain sounds. If your child is not yet school age and is showing
speech and/or language delays, a parent-infant or preschool program
with special emphasis on developing these skills is recommended.
Children with severe or profound losses
should be enrolled in a parent/infant program that addresses
their specific needs as soon as possible. These types of programs
are outlined in the next section. When school-age, children in
this category need ongoing monitoring of speech and language
progress and routine audiology checks. Hearing aids and assistive
listening devices (like FM systems) are essential, as is a favorable
acoustical environment. Your child may also benefit from the
use of an interpreter and/or notetaker in the classroom.
| Hearing is considered
normal when a person chan hear sound at a loudness of between
0-15 decibels. The table below shows the four categories
of hearing loss and the decibel level needed to detect sounds
in each category. |
| Mild |
15-40 dB |
Cannot hear a whispered conversation in a quiet atmosphere
at close range. |
| Moderate |
40-60 dB |
Cannot hear normal conversation in quiet atmosphere at
close range |
| Severe |
60-90 dB |
Cannot hear speech; can only hear loud noises such as a
vacuum cleaner or lawn mower at close range. |
| Profound |
over 90 dB |
Cannot hear speech; may only hear extremely loud noises
such as a chain saw at close range or the vibrating component
of loud sound. |
