Building an Inclusive Listening & Spoken Language Classroom
As an itinerant DHH teacher, I support classrooms like yours to ensure that acoustic access matches visual potential. By integrating small accommodations, checking technology daily, and planning seating dynamically, you empower your DHH students to thrive in their general education environment!
Fast Auditory Fact:
Traditional hearing aids do not restore normal hearing. In a noisy classroom, a student's brain works three times harder simply to parse speech from background racket.

Our state-of-the-art simulator runs directly in your browser using the Web Audio API. Click and drag nodes on an audiogram plot to craft high-frequency sloping or cookie-bite losses. Blend in background HVAC buzz, add classroom echoing (reverberation), and instantly toggle simulation on/off during speech playback to experience what your student hears.

â
Microphone Placement: Teacher's personal DM/Roger transmitter is worn centered, about 6-8 inches below the mouth. Avoid necklaces or jackets that scrape the microphone.
â
Device Check: Student's aids or cochlear implants have fresh batteries or a full charge, and visual indicators show they are turned ON.
â
DM Sync: Hold the Roger transmitter close to the student's receiver and press "Connect". Confirm the student hears the double-chime connection signal.
â
Visual/Caption Verification: Subtitle overlays are enabled on the main Smartboard and any online video materials planned for the day's lessons.
â
Seating Alignment: Confirm student's desk placement is clear of low-frequency HVAC noises and has direct line-of-sight to the main board.
Frequently Asked Questions
DHH students experience intense listening fatigue. Working double-time to lip-read and parse sounds results in mental exhaustion, causing them to drift or look away. Use a soft, non-invasive cue (e.g. saying their name, gentle shoulder touch) and use visual charts to break down assignments.
No, absolutely not! The Roger microphone automatically measures incoming speech volume and matches it, delivering a clean audio feed straight to the student's ears at a comfortable level. Shouting or talking directly into the microphone capsule causes cracking and highly distorted, loud sounds.
Passing the Roger transmitter pen is excellent, but if impractical during fast-moving group talk, always repeat the student's questions or comments! Example: "Sarah just asked if we need to do odd numbered math questions on page 42..." This ensures the DHH student hears what was asked.
Always **mute or turn off** the transmitter during side conversations with other staff, parent-teacher drop-ins, phone calls, or when stepping into the hallway or restroom! Otherwise, the student will hear your private audio clearly across structural classroom walls.
