Topic Area 2 - Effect of HL on Language & Learning Flashcards
What is the difference in training of educational audiologists and that of other audiologists?
No specialized training for educational audiologists; only training is on the job (but audiologists are typically ‘in the booth’ whereas educational audiologists are in the environment)
Be able to identify a few strategies for advising teachers about quieter classrooms. For example, what are HUSH Ups?
Make sure fans/radiators aren’t too loud, don’t be in a class right next to the gym, add felt/cover to bottom of chairs (HUSH Ups are pre-cut navy tennis balls)
Don’t use conventional tennis balls because they may release toxic gas
From the textbook:
Installing carpeting or cork on the floor
Hanging acoustical panels, cork, felt, or flannel bulletin boards on walls
Placing bookshelves or wall dividers to create quiet areas within the classroom
Apply window treatments (e.g., drapes) to decrease amount of reverberation
Cover ceiling with suspended acoustic tile
In the home, Dr. Ritter has advised us to educate parents about:
Distance from signal and keeping noise/media background to a minimum.
When distance and/or room acoustics make listening through only a hearing aid or a cochlear implant very difficult, there are other possibilities:
FM systems for home and school …ALDS (assisted listening devices) can augment hearing aids and CIs (around the neck FM, “easy pen”)

What does it stand for?
What is it?
What it stands for:
“Computer-aided transcription services” has become known as “real-time captioning” or “Communication Access Realtime Translation” services
What it is:
The instant translation of the spoken word into English text using a stenotype machine, notebook computer and realtime software; can be delivered on location or remotely
Personal FM versus Sound-Field FM systems
Personal FM:
- Main talker wears a microphone usually on a cord around the neck or clipped onto the shirt
- Speech signal conveyed into a transmitter, where it is frequency modulated on radio frequency carrier waves and transmitted to the client, who wears a receiver
Sound-field FM systems:
- Sound transmitted to loudspeakers that are positioned throughout the room (usually two in the back of the room and one near the front)
- Signal converted to an audio signal and played into the environment. Client’s personal HA microphone picks up the system
Audio boots and FM boots
- The receiver may connect to the patient’s HA by a direct auditory interface and an audio boot connection
- OR the patient may wear an FM boot at the bottom of the hearing aid
Neckloop
Transmits to the HA via the HA’s telecoil
Microphones and transmitters
Microphone: transducer worn by the ‘main talker’ (e.g., teacher) that picks up the acoustic signal and converts it into an electric signal;
- Transmitter: speech signal conveyed here and it’s frequency is modulated on radio waves and transmitted through the room to the person wearing the receiver
Advantages/disadvantages of personal FM/Sound Field FMs
Personal FM: better signal-to-noise ratios
Sound-field system:
o Beneficial for the entire room, even those without HL
o Do not require a patient to wear a special FM receiver so patient wears less hardware
Infrared systems
- Where they are typically used
- Advantages/disadvantages
-TV watching and movie theaters
- Not appropriate for outdoors (sunlight interferes w/ transmission)
- Signals cannot travel through walls; “line of sight” required for signal to be received
Induction Loop systems
Generally how it works
System that works by running a wire around the circumference of a room that conducts electrical energy from and amplifier; this creates a magnetic field, which induces the telecoil in an HA to provide amplified sound to the user
Hardwired systems - advantages/disadvantages
Can be used for listening to TV, radio, or music
Require the user to be tethered to the sound source (most patients do not want this)
The purposes of making the “invisible visible”
Hearing is invisible → the Ling 6 can make these child really active listeners and help parents be confident that their child is hearing
Conducting the Ling 6 Sound Test - Dr. Ritter’s vid
Need to have a quiet auditory AND visual environment (use quiet toys so that child is “captured” by the sound)
Administration:
Want to come out of quiet with a sound
Interrupted presentation (e.g., a, a, a; sh, sh, sh; unusual, so more likely to respond)
Better to conduct test twice
The need to vary wait times and order of presentation (so child can’t predict)
Daily use can reveal progressive hearing loss
Before it might otherwise become obvious
Use of the test with children with complex needs/multiple involvements:
-Sharing between 2 people: parents, siblings, etc.
–Siblings can help to model and demonstrate
-One person in front of child and one behind
–to watch child’s face to make sure there’s a consistent response
-Ensuring stable seating or lying down – not to interfere with listening and ability to respond with “stilling” or smiling or searching or using eye gaze
