Students Speak Classroom Best Practices

Video of "no device found" when checking FM connection

This is a quick video of the message that no device was found when checking the connection.  The easiest problem technique is to try a new battery.  If the device is not found, then contact the audiology office.

How to check FM connection with a Roger teacher microphone

If you are unsure if a student is connected or they claim the device is not working, you may check the connection through the Roger microphone.  If the device is connected, it will list the serial number of the student hearing device.  If it is not connected you will see a message "no device found".  If the device is not found, add a new battery and try again.  If you receive the message again that the device was not found, contact audiology. 

Roger Teacher microphone and "FM"

A short video on how to connect a student's FM device to the Roger teacher microphone.  In the video, the hearing device is on a counter.  In a typical classroom, you will hold the teacher mic up close to the student's ear.  You have to connect each ear separately. 

Soundfield Infrared Microphones in the Classroom

All schools in Cobb County should have boxes of Infrared Microphones that can be paired with the classroom projector.  The microphones are easy to use.  There are some concerns about the loudness level of the system bleeding over into adjacent classrooms.  It is advised you adjust the volume control on the microphone to a comfortable listening level, not a rock band concert level or sports arena level.

How to Use Splitter Cable

How to Use a Splitter Cable.

If a teacher is showing a video through the classroom projector, you can set up the Teacher Mic (Inspiro) so the sound will be heard from the classroom speakers AND the sound is delivered to the student's hearing assistive technology.  You will need:  1) Inspiro (teacher mic) 2) splitter cable 3) patch cord.

Auditory Neuropathy Disorder examples

This example is often used in Audiology to demonstrate various "hearing loss" caused by Auditory Neuropathy.  In Auditory Neuropathy, the outer hair cell nerves in the cochlea function normally.  This is in contrast to sensory hearing loss where the outer hair cells are damaged and hearing aids help compensate for this damage.  Treatment for Auditory Neuropathy can include hearing aids (with caution), cochlear implantation, or ASL or cued speech.  At this time, we cannot predict the severity of the Auditory Neuropathy based on objective tests (i.e. Auditory Brainstem Response).  We have to monitor the child's auditory skill development (i.e. head to turns to mom's voice, startle to loud sounds) and later speech and language skill development.  In addition, there have been cases where the Auditory Neuropathy resolved in later years.

Auditory examples of hearing loss

This You Tube video does not have a video, but recorded samples of hearing loss.  I think this simulation does an accurate job relating to speech audibility and not just loudness level.  Notice the demonstration of the mild hearing loss and how you can hear a lot of speech sounds, but not the /s/.

FM simulation

FM simulation in the classroom.  The video is several minutes long but accurate and eye opening.  A good video to show general educational classroom teachers and parents.
