Hearing Assistive Technology in the Classroom

CLICK HERE TO SEE HOW TO WEAR THE FM TRANSMITTER!
This is the Auditory Equipment that the Classroom Teacher of the Deaf/Hard of Hearing Student uses in the classroom.
The student's D/HH Case Manager and the student's IEP will refer to this as the HAT Hearing Assistive Technology.

The photo above,  is a Phonak FM Transmitter with a microphone/iLapel.
You must allow the cord that connects the mic to the FM Transmitter to dangle since this cord serves as the antenna for the wireless system.

The Roger Pen-
New in some of our high schools is the Roger Pen!  It's a cutting-edge wireless microphone that enables people with hearing loss to hear and understand more speech in loud noise and over distance.  




So What is an FM System??
(Frequency Modulated System)
An FM system is a wireless system designed to help
someone better identify and understand speech in noisy situations and over distances of up to 15 meters (50 feet).
Our FM systems work together with hearing aids.
It works like this: the person speaking (usually, YOU, the teacher) wears a transmitter with a microphone. This transmitter picks up important speech sounds and uses harmless radio waves to send these to the student's FM receivers, which a child wears behind the ear and is connected to their hearing aids.
The result? The child hears the speaker’s words directly in their ears, without any distracting background noise, allowing them to participate fully in the classroom conversation.

This plug appears to be round,  but it's a trapezoid shape which fits into the bottom of the transmitter.



The D/HH student can not wear headphones while wearing their Hearing Aids or CIs.  Each student should receive the two cords shown above (a split cord & a patch cord), to attach the transmitter to a lap top/desk top computer and/or a smart board.



This patch cord is plugged into the bottom of the FM Transmitter and into the computer. (Use the same plug as headphones.) This way, the student is able to hear the computer through their hearing aids or Cochlear Implants.

The split cord is used for the smartboard.
Note that the split cord is attached to a patch cord which is attached to the smart board and the transmitter.

Batteries for the Hearing Aids.
Remember to change the batteries every Monday.
If your student is in 2nd grade and above;
they should be changing their own batteries.  
We recycle these batteries.
Please put old batteries in a zip lock bag and return them to me in December and May. (click here to read - THE DANGERS OF BUTTON BATTERIES)


 Hearing Aids with built in FM Receivers.

Notice the red sticker = right ear and
the blue sticker = left ear. 
When your student changes his/her battery,
they also need to clean the ear wax out of the mold. 
Built up ear wax will clog the tube and prevent it from working properly.
Please, do not use a paper clip!!
You will be given plastic, crooked-neck toothpicks that are very useful in cleaning out ear wax without damaging the tubes.

Everyone received a case for the hearing aids.
The battery door must be opened to turn OFF the aid.
If you hear a high pitch squeeling sound once the aids have been put into the case;
the aids are not turned off. 


This is a MyLInk FM Receiver.
This is used by a student with Cochlear Implants. It's worn around the student's neck and receives from the Teacher's FM Transmitter.
It also has to be recharged at the end of school and works with the teacher's FM system.
Please do not wear during PE and recess.

Some students use a bag of sound /toteable.
The bag is placed on the desk next to the student or on the floor - where ever the student is sitting.

The transmitter and microphone for the
bag of sound.


The bag of sound also has it's own battery charger that will need to be recharged daily. 
~~~~~~~~~~~~~~~~
Remember the daily sound check using the check sheet in the student's folder. This tells you, the student, and me, that all the equipment is working.
I hope this has helped or will help in the future! 
Please let your D/HH Teacher know if you are going on a field trip like a museum and taking the HAT (school hearing aids and FM transmitter) with you. The Teacher is responsible for the HAT!
The student should not wear the HAT for recess, on Field D
ay or on an overnight event. 

Ask the student if he/she would rather use their personal hearing aids for a field trip.  
If something is not working,  please contact your D/HH Special Ed. Teacher ASAP.
Either Ms. Lynda Entsminger from Audiology(678-581-7400) or your D/HH Teacher will get back with you.
