Step-by-Step Instructions
Step 1: Identify the appropriate assistive listening device
Select a device suitable for the student’s hearing needs and classroom environment. Consider options like FM systems for active movement, infrared for larger rooms, or personal amplifiers for one-on-one use.
Tip:
Consult with the student’s audiologist if unsure about the best type of device.
Check:
The chosen device matches the student’s needs and has all necessary components (microphone, receiver, power source).
Step 2: Charge or insert batteries into the device
Ensure the device’s batteries are fresh or fully charged. Insert batteries as per the manufacturer’s instructions or connect the device to a power source.
Tip:
Test the device after inserting batteries to verify power is working.
Check:
The device powers on without error messages and is ready for use.
Step 3: Connect the microphone or transmitter
Attach the microphone or transmitter to the teacher’s or speaker’s clothing, ensuring it points toward the sound source. Secure it firmly to prevent movement during class.
Tip:
If using a wireless transmitter, ensure it is paired with the receiver and within range.
Check:
The microphone/transmitter transmits audio clearly to the receiver without static or dropout.
Step 4: Configure the receiver for the student
Turn on the receiver and set the volume to a low level initially. Confirm it is paired properly with the microphone/transmitter, following the device’s pairing process.
Tip:
Adjust volume gradually to avoid sudden loud sounds that could discomfort the student.
Check:
The student can hear the microphone clearly without static, and the volume can be comfortably adjusted.
Step 5: Place the receiver on the student
Secure the receiver in the student’s hearing aid, cochlear implant, or pocket. Attach to clothing using clips or lanyards if available.
Tip:
Ensure the receiver is close enough to the student’s ear for clear audio transmission.
Check:
The student reports hearing sounds clearly and comfortably, with no feedback or static.
Step 6: Test the device in the classroom environment
Speak from the teacher’s position and verify the student can hear clearly through the device. Adjust volume as needed.
Tip:
Check for background noise or interference, adjusting microphone placement if necessary.
Check:
The student demonstrates understanding of spoken instructions during the test, confirming clear audio transmission.
