Do Deaf Kids Need to Hear Their Classmates Comments?

You are guiding a discussion about the results of a science experiment investigating the effects of gravity on the growth of plant roots. In all cases, the roots of the seeds grew downward. Students are offering responses about why this might have happened.

The student in your class who is deaf hears you (through the FM) pose the question. “What are some reasons the roots might be growing downward?”

“The oo ahh  -ooee  or a oa ee a,” she hears one student suggest.

Another student answers, and she hears something like “a i something something something ou.”


It happens. Several times every day. I’ve experienced it.

I have observed students who are deaf participating in general education classes. They probably hear the teacher rather well. The teacher uses an FM and instinctively uses a louder-than-usual voice when addressing the class.

But students don’t use a louder voice. Many, many times, students use a softer-than-usual voice when speaking out in class. Sitting at the perimeter of the room,  I couldn’t understand what students said at this volume. I highly doubt that the student who is deaf understood them either.

Students should use the FM microphone so the D/HH student has access to their answers, questions and comments.

Best Practices: Pass the FM microphone for student questions and comments.

When teachers develop the habit of sharing the FM microphone with students, the student who is D/HH has access to ALL spoken language in the classroom.

It may seem awkward at first, but it can quickly become a classroom expectation. When a soundfield FM is used, all students benefit from access to the shared microphone.

Ask your educational audiologist about the availability of a pass-around mic, which limits the noise associated with handling the mic. 

Repeating  student comments and questions can benefit many students.

Teachers are modeling good public speaking  skills when they repeat the comments and questions of ‘the audience.’ Teach this as a leadership skill and you will be contributing to the development of our next generation of audience-conscious speakers.

Other Strategies

Discuss with the D/HH student how he can let you know he didn’t hear or understand.

Self advocacy is an important skill for all learners and community members. In school, we learn to function as part of a cooperative group, but also need to advocate for our individual needs.

Students who are deaf need to know their own needs regarding communication and language. They also need to be aware of what the general public knows about their needs (answer: very little). They need to have specific language for explaining their needs. And the criteria for having those needs met.

Post prompts on the student’s desk.

 Could you repeat that, please?

I didn’t understand the question. 

Consider a private signal for students who can’t be encouraged to speak up. The signal will remind you to repeat what was just said.


Just like all students have the right to access the building where education takes place; so all students have the right to access all the information being presented. The student who is deaf or hard of hearing needs to know what classmates are contributing in addition to the teacher’s communication. 

Speech and Deafness

In IQ & Deafness we discussed the assumptions we make about intelligence based on a person’s speech and language. I named four characteristics of students who are deaf or hard of hearing (D/HH) that can lead others to misjudge their intelligence. The first of these characteristics was imperfect speech. Other features include imperfect language.

This man has perfect diction, so he’s obviously smart.

Proposition:

We unconsciously make judgments about the intelligence of an individual based on the characteristics of their speech.

Think about the actors who played the aristocracy  in the TV series Downtown Abbey – they all had perfect speech – each word pronounced carefully and precisely.

Now think about movies that have bumbling sidekick bad guys who talk with thick tongues and mispronounce words right and left.

As soon as they open their mouths, you know these guys are idiots.




WHAT Exactly IS SPEECH? 

“Speech” refers to the sounds that make up our words. A common baby’s first word, “Momma,” has three sounds: mm, ah, and uh.

                             m + ah + m + uh  =   Momma Momma!

Speech is NOT making sentences, using good grammar or knowing Nouns vs. Verbs.

Stated simply:

SPEECH is using the parts of your mouth  to make sounds. 

How Did You Learn to Speak?

Who taught you to talk? The answer is (if you had typical development) “no one”.

Human brains are programmed to learn to talk just BY LISTENING to adults talk. That’s it. The typical baby in a typical environment will learn to talk without any help.

HERE’S HOW WE LEARN TO TALK

  • A baby listens to speech and imitate the sounds he hears — again and again.
  • For months, he listens and babbles, listens and babbles.
  • While babbling, he is listening to himself and refining his sounds, trying to match them to the sounds he hears from others.
  • He also hears the melodic patterns of our speech and copies them when babbling. (This is adorable to hear.)
  • By age 6, the sounds and melodic patterns he hears from himself match what he hears from others.

WHY IS DEAF SPEECH SOMETIMES IMPERFECT?

A baby who is born with a significant hearing loss doesn’t hear these sounds until he receives a hearing aid or cochlear implant. And even then, he is hearing the sounds imperfectly through man-made devices.

Imperfect sound going into the ear makes it more likely that imperfect sounds will come out of the mouth.

SLI SLO

SLI = SLO Speech/Language In = Speech/Language Out

Even with hearing aids and implants some sounds are difficult to hear. These are the sounds often left out of the speech of someone who is deaf. He doesn’t say what he doesn’t hear.

Even after a child learns to make the sounds of our language, he is often unaware when they are used because he isn’t hearing them. A common example is s at the end of words.

The speech problem becomes more complicated when we think about the child hearing his own speech. When a child fails to include the in the word cats, he is unaware of the omission because he hears himself speak in basically the same way he hears us – imperfectly. When you and I get to the end of the word cat, we know we haven’t heard the s yet, so we add it. So the production of those tough sounds must become a conscious act, and maybe eventually deeply ingrained habit.

HOW DO CHILDREN WHO ARE DEAF LEARN TO TALK?

A child who is D/HH  needs to be directly taught how to make the sounds of their language. He learns where to place his tongue, what shape his lips should make, whether or not to add his voice, and many other variables.

It’s more complicated than you think

Consider tongue placement: /t/  vs. /k/  

  • The /t/ sound brings the tongue up just behind the teeth.
  • The /k/ sound brings the tongue up at the back of the throat.

Is your voice on or off?  /f/  vs  /v/ 

  • When we make the /f/ sound and the /v/ sound, our tongue is in the same place
  • but for /f/, we don’t use our voice, and for /v/ we do

When you consider all the challenges a student who is deaf overcomes to learn to talk, can you honestly question his intelligence?

 

Implants & Hearing Aids: NOT a FIX

UNLIKE EYEGLASSES & VISION,

cochlear implants

& hearing aids

do not fix hearing loss.

 HEARING AID     not equal       eyeglasses

Many times teachers have said, “I know she can hear me,” usually followed by comments that openly state or imply that the student is intentionally ignoring what was said.

Yet we all know that hearing something doesn’t mean you understand it.

Think about listening to a radio that isn’t tuned exactly to the station you want to hear.

You  HEAR  the voices,radio-dial_00273392

but they are DISTORTED

and there are lots of BREAKS

in the sound and STATIC around it.

That’s one way to imagine listening with a hearing aid or implant.

Hearing aids and implants

can get the radio tuned more closely to the right place on the dial.

But IT’s NOT a PERFECT SIGNAL LIKE YOU & I HEAR. 


Here’s a demonstration of listening through a hearing aid at close distance, 10 ft., with background noise and with a personal FM.

Here’s a demonstration of listening through a cochlear implant.

Simulation begins at 2:44.


 HOW ARE THEY DIFFERENT?

Both hearing aids and implants are programmed to make voices sound as loud as necessary and as clear as possible.

One is not “better” than the other. Some types of hearing loss can benefit from a cochlear implant. Others get full benefit from a hearing aid.  Which device a student uses can depend on her individual hearing loss, insurance coverage, and ultimately, parent choice.

So when a student seems to be ignoring you, or just doesn’t seem to ‘get it’, stop and remember that she is still deaf – even with her state of the art listening device.
