ASSISTIVE LISTENING DEVICES TECHNOLOGY FOR LEARNING WITH HEARING
IMPAIRMENT
Hearing Aids: hearing aids are amplification devices worn on
the body, behind the ear, or on the eyeglass that amplify sound. Hearing aids
are limited by their need to be used in a quiet and structured environment, as
well as their need for the user to be situated close to the sound source.
Telecommunication Device for the Deaf (TDD): TDD enables
hearing impairments to receive phone calls using technology attached to the
phone that has a small keyboard and screen for typing. While this device is not
used regularly in the classroom, it is the most widely known device today.
Frequency-Modulated: (FM) Amplification Systems: FM
amplification systems create a link between the teacher (with microphone) and
the hearing aid for the HI student. This technology works effectively in the
classroom by greatly reducing background noise and freeing the teacher to walk
around the room. As a result, this is of most commonly used assistive technology
devices used in schools because of it’s “versatility and portability for use in
or out of the school building.”
Audio Loops: Audio Loops are adaptations of
Frequency-Modulated (FM) Amplification Systems where the loops amplify sound
directly through wire connection radio waves to the hearing aid. This
technology decreases background noise and increases teacher mobility, by
allowing the teacher to move about the room freely.
Infrared Systems: this new technology uses a transmitter to
send the sound invisibly to hearing impaired listeners. This technology is
considered to be better for public places, as well as better for students and
teachers alike, due to it having no wires and cords.
Cochlear Implants: implants can provide sound for people with
“profound hearing impairments. Implants enable the wearer to hear sounds
previously indistinguishable by bypassing the damaged part of the inner ear and
stimulating the healthy nerves.
Televisions: Wireless
technology in personal listening systems provides direct and amplified sound
with adjustable volume and little background noise.
Captioning: Captioning
allows spoken word on the television to be translated into typed English for
the viewer to read. This type of assistive technology is used most widely in
the regular classroom environment. Additionally, amplified telephone ringers
allow customized selection of volume and frequency for those who may have
difficulty in hearing the phone ring.

ASSISTIVE DEVICES TECHNOLOGY FOR
LEARNING WITH COGNITIVE IMPAIRMENT
Educational Technology
Educational
technology is sometimes referred to as “e-learning,” “instructional technology,”
or “learning technology,” and usually refers to the use of technology to
support the learning process. Although the term can refer to all kinds of
related technologies, e.g., photographs, films, videos, audio recordings, etc.,
it is usually used to talk specifically about computer technology.
Durable Medical Equipment
Durable
medical equipment (DME) generally consists of items that can withstand repeated
use and that are primarily and customarily used to serve a medical purpose that
is usually not useful to a person in the absence of illness or injury. Examples
of DME include items such as iron lungs, oxygen tents, hospital beds,
wheelchairs, and seat lift mechanisms that are used in the patient’s home and
are either purchased or rented.
Cognitive Orthoses/Cognitive
Prosthetics The
terms “cognitive orthoses” and “cognitive prosthetics” are used
interchange-ably and are defined as compensatory strategies that alter the
patient’s environment and are directed to an individual’s functional skills. Fallon-As
clinicians and researchers seek new ways to serve people with cognitive and
neuropsychological disabilities, many have incorporated computers and other
advanced technologies into clinical interventions. The following attributes of
a cognitive prosthetic:
• Uses computer technology.
• Is designed specifically for rehabilitation
purposes.
• Directly assists the individual in performing
some of his/her everyday activities.
• Is highly customizable to the needs of the
individual.
Rehabilitation Technology The term “rehabilitation technology”
refers to the systematic application of technologies, engineering
methodologies, or scientific principles to meet the needs of and address the
barriers confronted by individuals with disabilities in the areas of education,
rehabilitation, employment, transportation, independent living, and recreation.
The term includes rehabilitation engineering, assistive technology devices, and
assistive technology services.
AHome Modification/Environmental
Adaptation “Home
modification” includes any change to a home that fosters the independence and
safety of individuals with disabilities or that allows people to carry out
their daily tasks more easily (Pynoos, 1998). Home modifications can range from
installation of inexpensive items (e.g., grab bars) to more costly structural
changes such as widening of doorways, renovation of bathrooms and kitchens, and
installation of ramps. Home modification is often referred to by the more
general term “environmental accessibility adaptation.” Examples of home
modifications include removing throw rugs to prevent slips and falls,
installing grab bars in the bathroom for stability, and building a ramp up to
the entrance of a home.
