assistive devices
|
|
|
What is ALD?
pg64 |
ADs used by people with deafness
assistive listening devices |
|
|
What are the four types of ALDs?
pg64 |
1. FM systems
2. hardwire 3. induction loop 4. infrared |
|
|
What is ILA?
pg64 |
induction loop amplification
|
|
|
What ALD is used with a telecoil?
pg65 |
ILA
|
|
|
What are benefits and limitations of hardwire systems?
pg64 |
Inexpensive
Lightweight and portable Limited by wire length May have reduced sound quality |
|
|
How does a hardwire system work?
pg64 |
Microphone in front of a speaker is wired to a direct audio input (DAI) of a hearing aid or box that sends the signal to headphones.
|
|
|
How does an induction loop amplification (ILA) system work?
pg64 |
Wire is looped around the perimeter of a room. A receiver converts a microphone signal to electrical energy, which creates a magnetic filed that is detected by a telecoil.
|
|
|
What are the benefits and limitations of induction loop amplification?
pg65 |
Does not require hard connection to listener.
Works with telecoils in hearing aids Inexpensive Wire must be installed Not portable Affected by orientation of telecoil Too much distance from loop decreases signal strength multiple loops in same building can cross-interfere |
|
|
How does an infrared system work?
pg66 |
microphone⇒acoustic signal⇒electrical energy⇒infrared light via a transmitter
infrared light⇒receiver⇒electrical signal⇒acoustic signal used for theatrical or musical productions |
|
|
What are the benefits and limitations of infrared systems?
pg67 |
1. inexpensive
2. wireless 3. stays in a specific listening area 4. can be used in adjacent rooms 1. needs direct line of sight 2. will not work in sunlight 3. person must stay in one area |
|
|
What are the benefits and limitations of FM systems?
pg69 |
1. portable
2. wireless 3. simple 4. used inside or outside 5. can be used simultaneously in adjacent rooms 6. electromagnetic interference is not a problem 7. receive can be out of line of sight 8. great sound quality 1. radio interference possible |
|
|
A t-coil eliminates what when on the phone?
pg71 |
acoustic feedback
|
|
|
What do people with severe hearing loss utilize for using a phone?
pg71 |
text telephone (TT)
telephone device for the deaf (TDD) |
|
|
TDDs communicate with...
pg72 |
other TDD devices or through a relay device
|
|
|
What is relaying?
pg72 |
The process of transcribing spoken words into text and vice versa.
Used when only one TDD device is involved. |
|
|

pg383 |
disability
|
|
|
Impairment is...
pg383 |
one part of disability that can be measured audiometrically

|
What four things provide a complete approach to understanding the abilities and needs of the hearing impaired?
pg384 |
1. assessment tools
2. audiometric performance measures 3. data logging 4. self-report |
|
|
Why do we assess the consequences of hearing loss?
pg384 |
1. need to obtain info to understand the HL
2. understand the psychosocial aspects of HL 3. discover specific hearing environments for a patient |
|
|
The audiometric assessment assists in what two areas?
pg384 |
diagnosis
rehab |
|
|
What does a basic diagnostic test battery consist of?
pg384 |
1. immittance
2. measures of uncomfortable level (UCL) 3. pure-tone air and bone conduction audiometry 4. speech threshold tests 5. word recognition tests |
|
|
What are benefits of self-report questionnaires?
pg386 |
1. easy & inexpensive
2. used for a wide variety of purposes & populations 3. noninvasive |
|
|
What are the three essential outcome measures that are important in assessing overall hearing aid fittings?
pg387 |
1. hearing aid usage
2. satisfaction and benefit 3. speech recognition performance |
|
|
What is the SAC?
pg388 |
Self-Assessment of Communication
|
|
|
What is the SOAC?
pg389 |
Significant Other Assessment of Communication

What is the "communication predicament of aging"?
pg399 |
the self-fulfilling prophecy of the elderly losing hearing then displaying stereotypical behavior that is misinterpreted which leads to social isolation
|
|
|
What is geriapathy syndrome?
pg400 |
when an elderly person is hard of hearing, he tires of trying to understand conversations and after a while will just give up trying, disengaging in social interactions
|
|
|

|
|
