Raising and Educating a Deaf Child

International experts answer your questions about the choices, controversies, and decisions faced by the parents and educators of deaf and hard-of-hearing children.

Cochlear Implants and Hearing Aids

I’m a pediatric occupational therapist who only occasionally works with deaf children. I don’t have time (or a library) to read papers and books about deaf children. Is there something like Cliff’s Notes on deaf kids?

Question from R.P., Virginia. Posted July 16, 2014.
Response from Marc Marschark - NTID

Yes, Virginia, there is a Santa Claus. (sorry!)

Raising and Educating Deaf Children is a new site offering objective, evidence-based information for policy-making and practice associated with raising and educating deaf children – with an eye to improving them. New eBulletins are posted quarterly; each includes sections on The Issue, What We Know, What We Don’t Know, and Implications about various topics, all written so as to be accessible to parents as well as professionals.  eBulletins include Further Readings with content offered free of charge by Oxford University Press.

My 4 year old son has been diagnosed with severe sensorineural hearing loss in both ears. He was not born this way; we believe he lost his hearing sometime between 2.5 and now. He was just diagnosed in June and he will be getting his first pair of hearing aids at the end of July. I’ve been told by his ENT and Audiologist that we need to make a decision about cochlear implants (CIs) very soon. My son had lots of vocabulary and speech sounds; he now is a little difficult to understand but communicates with family and friends. My question is where can I find good information about CIs and also why must I rush to make a decision?

Question from M.H., New Jersey. Posted June 27, 2014.

It sounds as if your child’s loss predominantly occurred after he acquired verbal speech and auditory language, so his deafness is categorized as “post-lingual.”  This means your son’s brain has a memory of what speech sounds like, even if that memory and how to reproduce it are fading a bit. That is one reason why implantation is recommended sooner rather than later – research has demonstrated that the shorter the lag between onset of the hearing loss and input from a cochlear implant, the better the child does.  We believe that is because the auditory memory (part of that auditory path design) has had less time to “forget” the sounds of speech.  There are lots of research articles that talk about keeping that time-frame short between onset of hearing loss and use of the CI, although outcomes are more variable than they might appear.

The signal from the hearing aid is amplified speech and other sounds, so your son will hear things at a louder level with his aids.  The sounds will be distorted and some sounds may not be transmitted very well (sounds like /sssss/ and /shhhhhh/).  His brain and his ears are connected by a path of nerves (the auditory path), and the signals that the ears receive must be interpreted by the brain.  There is big difference between the signal provided by a hearing aid (loud speech) and the signal transmitted by the cochlear implant (kind of like Stephen Hawking’s electronic speech).

Without knowing more details as to the cause of the hearing loss, it is unclear whether there are specific reasons for recommending earlier implantation – some audiologists and ENTs simply believe that CIs are for almost every deaf children and the sooner the better. However, I can tell you that there are some conditions that can cause a bony growth to happen in the cochlea (which is the organ if hearing) and, if so, this growth begins after the hearing loss in a gradual and slow manner.  If this occurs, the longer one waits, the more difficult it can be to insert the electrode of the cochlear implant.

There may be other reasons your healthcare providers are wanting you to make a decision, but you need to do your homework first. One of the predictors of children’s success with CIs, literally, is how much time their parents spend getting information on the subject. Here are two links that let you compare what the signals of a hearing aid sound like and the signals of a Cochlear Implant sound like

Over the years I have had many hard of hearing students deny their hearing losses and refuse to wear any amplification. I usually tell students that amplification needs should be discussed with their parents. I generally support whatever the parent wants to do.

One of my students’ parent wants to develop a contract for hearing aid and FM use next school year for her seventh grader. The prospective seventh grader will not acknowledge the hearing loss or any of its impact. At this point, I am truly concerned for the student’s well-being. My inclination is to teach clarification and compensatory skills while working to help the student come to some acceptance of the hearing loss.

What does research say about acceptance of hearing loss or amplification use in adolescence?

Question from S.K., Ohio. Posted June 17, 2014.

Your question about available research is difficult to answer – after all these years, we still only have anecdotes to inform us, and not even enough of these to work with.  But we can take an educated guess at what this young person is thinking: “I have a problem but I want it to go away; all I want is be like everyone else so I will pretend I am.”

We do know quite a bit about acceptance in general, though: a mindset that first requires the hard work (and pain) of looking at a situation honestly.  This young person may need to work with a counselor to “get there.”  Additionally, while working on the strategies mentioned, perhaps you might ask her to chat about the concept of resilience.  It’s often more comfortable to talk less about the issue at hand (amplification decisions) and instead discuss a bigger but semi-related topic, as in: “People are talking a lot about resilience these days, have you noticed? When adversity occurs, how do people rebound? What strengths do people draw upon to recover and move forward? Any examples come to mind?” Just generally about “people,” but most of us insert ourselves into the answers.  All children need practice talking about their emotions. She is fortunate to have you in her life.

Our district audiologist wants to put all DHH students on personal FM and remove the class soundfields altogether. I find conflicting research on this. The DHH teachers don’t want to get rid of the class soundfield systems. Can you please confirm either the benefits or detriment of keeping the soundfield in place in addition to personal FMs?

Question from E.W., California. Posted June 12, 2014.

By class soundfield system, I assume you mean a room equipped with two or more speakers that broadcast the desired signal into the desired space.  The problem with these systems is that everyone in the room is exposed to the signal and, depending upon where the deaf or hard-of-hearing student is sitting, there could loss of signal strength over distance.  Personal FM systems have the advantage of being set up specifically for the user, whether the individual is using a hearing aid (s), a cochlear implant, or both.  The signal is clear, coming directly from the teacher to the student.  The signal does not lose strength over classroom distance, and the teacher can use one microphone to connect to several students at the same time.  Also, there is no “carry over” into adjoining classes as there might be with a sound field system (depending upon the decibel level of the signal).  In my opinion, the FM is superior though more expensive. Two additional notes:  (1) Students with milder hearing losses may do best with soundfield system while those with severe to profound losses are likely to do better with FM. (2) It is unclear why a person would remove an existing soundfield system unless maintenance is an issue.

Our son was born deaf and has cochlear implants. He is now 6 years old and in regular classroom with assistive devices. He seems to have a real trouble focusing and some issues with getting angry, upset, crying at times and arguing with adults. We are wondering if there are things we can do to help him gain better control of his emotions and get better focus.

Question from A.B., Oregon. Posted April 28, 2014.

It’s very important to remember that using assistive listening devices can be extremely stressful and tiring.  Cochlear implants have become very sophisticated and can be highly effective for many children and adults.  But, many children and adults still need to work quite hard to make sense of the auditory input they are receiving and process all that information.  School can be tiring, too.  So, one first step is to look at the times and situations that are most difficult for the youngster—the situations that bring up the most tears, anger, and arguing.  These may be times when he has been listening and working extra hard to hear and understand everything and everyone and is tired and worried that he hasn’t gotten it all.

Tracking the times and situations that are most difficult can also help teachers and parents to intervene before the child has reached that peak of frustration and can no longer regulate their emotions (leading to crying, arguing, and anger).  Once a child has “gone over the edge,” so to speak and is very upset, adults can mostly just help them gain control again.  That might mean getting away from the situation, waiting out the outburst, keeping them safe, etc.  But, if adults are able to recognize the warning signs, then intervening before control has been lost is possible.   Helping children learn to manage difficult times while they are still in control of their emotions can be done through conversations, modeling of appropriate behavior, offering alternative activities, and basic empathic statements.   And always remember to show children things they can DO when upset, as opposed to telling them what they should not do.  Not doing things is much harder than having an appropriate alternative.

I work with a CI student who is in 2nd grade. He received one implant at the age of 3 and now has two. He is unable to comprehend what he reads for the most part. I realize CI children have difficulty learning to read. My question is: What is your opinion about retention of CI students. This particular child is the youngest student in his grade with a birthday falling just at the deadline day for entering school. I feel he needs another year of language skills (academic and life vocabulary) so that he even has a chance of success. If he were not a CI student, I would recommend retention because of delays and his age.

Question from E.T., South Carolina. Posted April 21, 2014.

If the child needs to be held back, he needs to be held back. Whether or not he has a CI  should not change the educational decisions. At the same time, retaining a child and just giving him the same instruction is not going to solve the problem. I would recommend that first you make sure the implants are working and, second, that the child receives a full diagnostic reading assessment. My hunch is that he needs intensive and explicit phonics instruction but it depends on the results of the assessment.

Can you please suggest some good articles, research or data to support having a TOD in a classroom with a 5 year old with significant delays “across the board” (the student has bilateral CIs, no sign language, extreme speech delays [apraxia?])?

Question from J.B., Vermont. Posted April 2, 2014.

Given the huge individual differences among deaf children with multiple challenges, this is an impossible question to answer. You really are (or should be) looking for information relevant to a very specific child, and we don’t have much to go on.  How significant are the delays?  Is the child using the CIs successfully?  What is the cause of the extreme speech delays? Has there been an assessment that suggests apraxia or is that a guess, and if the latter, based on what? Does the child not use sign language because s/he has not responded to it or because s/he has not been exposed to it?

You can find articles and chapters about the educational needs of deaf children with additional disabilities (see below), but you really want to know why that 5year-old should have a teacher of the deaf.  You will not get that from an article.  You are going to need a comprehensive evaluation done by people who know what they are doing and can communicate effectively with the child.  There is no one right answer; it depends on the needs of each child.

Is there research to support why an additional year of preschool is considered appropriate for a child who is deaf and uses cochlear implants to develop language skills rather than moving on to kindergarten placement?

Question from A.H., Virginia. Posted March 4, 2014.

There does not appear to be any literature on this nor any general conclusions about what is or is not appropriate. It would definitely depend on the individual child and a full assessment of that child’s abilities.

I work in schools in Madrid Spain. We are debating the usefulness of Cued Speech for reading in deaf children with CIs. What are the latest results on this and how generalizable to Spanish children are these results?

Question from M.P., Spain. Posted February 5, 2014.

There are reasons to believe that Cued Speech may help deaf children with cochlear implants to learn to read and write. Cochlear implants provide auditory information that may be not precise enough to develop accurate phonological representations. Consequently, the reading and spelling skills of children with implants may be delayed compared to the acquisition of these skills by hearing children (with the same instruction). Those children who receive Cued Speech combined with the audio-visual input may develop more precise phonological representations, and better phonemic awareness which is an important skill for learning to read.

There are at least two empirical studies showing better reading, spelling, and reading related skills in deaf children with cochlear implants exposed to Cued Speech compared to deaf children with implants and not exposed to Cued Speech:

I am living in India and fostering a 6 year old boy who has 95% hearing loss. He used to live in an orphanage and came into my foster care in July. Prior to this no one noticed that he was deaf. I want to look into getting cochlear implants for him, but have been told that because of his age and that he has gone 6 years having no auditory input, the CIs won’t work. Thoughts?”

Question from N.C., India. Posted October 30, 2013.

Amazing that this child went six years until his hearing loss was discovered. This used to happen more than we would like to admit here in the United States, but thanks to newborn hearing screening we are usually able to diagnose hearing loss much earlier now.

Several things that make me curious relate to whether or not to pursue the option of cochlear implantation. I am curious as to whether this little guy has any vocalizations and how he makes his needs known. Do you have a sense whether he is bright and learns quickly? The reason I ask this is that sometimes children who are quick learners are able to slide under the radar and perform well in many arenas and their hearing loss gets over-looked. Alternatively, children who have multiple developmental delays in motor skills, learning, self-care, and if they have a lot of health issues as well, their hearing loss goes undetected as other health issues are the focus of intervention. I am also curious as to whether he ever had some hearing. If he does have the ability to vocalize he may have had hearing at one point in time.

First of all, I think you need to assure that this boy has access to language. As a child with profound hearing loss without amplification/implants he will need to have access to a signed language so that he can learn to communicate with the world. At this point, access to language (sign) is a main priority. In addition, I would also encourage you to advocate for a cochlear implant evaluation. He may indeed be a wonderful candidate. We know that children who learn quickly, who have had hearing, who have support to learn to listen and who are exposed to speech consistently will learn to produce the sounds of their language and within 4 years of CI listening experience, they may be able to produce a majority of the sounds, even if they get a relatively late start.
