TED Talk
• Establishing a Sound Foundation
• Dr. Karl R. White is a Professor of Psychology at Utah
State University and the founding Director of the National
Center for Hearing Assessment and Management
(NCHAM).
• Recognized as one of the world's leading authorities on
early identification and treatment of hearing loss in infants
and young children.
• He has hundreds of publications and presentations at
scholarly meetings, and has been invited to more than 30
countries to assist in the implementation of newborn
hearing screening and intervention programs.
Case Studies
• Newborn identified at birth with connexin 26, severe to
profound bilateral hearing loss, normal hearing parents
• Newborn identified at 2 years with rapidly progressive
bilateral SNHL, parents have a profound loss
• Seven year old recently identified with unilateral severe
SNHL
• Middle school male with normal hearing but auditory
processing problem in noise
• Fourteen year recently survived bacterial meningitis
resulting in bilateral SNHL
• Dad, suffered sudden onset mild bilateral SNHL
• Grandmother, slow progressive bilateral SNHL

AR Definition
“The assessment, intervention, and
management of communicative
consequences of hearing loss”
(unknown author)
ASHA
Aural rehabilitation refers to services and procedures for
facilitating adequate receptive and expressive communication in
individuals with hearing impairment. (ASHA, 1984, p. 37)
Audiologic/aural rehabilitation (AR) is an ecological,
interactive process that facilitates one's ability to minimize or
prevent the limitations and restrictions that auditory
dysfunctions can impose on well-being and communication,
including interpersonal, psychosocial, educational, and
vocational functioning.
(American Speech-Language-Hearing Association. (2001). Knowledge and Skills
Required for the Practice of Audiologic/Aural Rehabilitation [Knowledge and Skills)
David Hawkins
Anything that facilitates:
1) hearing,
2) understanding of hearing loss,
3) coping strategies,
4) acceptance of hearing loss, and
5) involving communication partners.
(Hawkins, D. 2003)
Mark Ross
Any device, procedure,
information, interaction, or
therapy which lessens the
communicative and
psychosocial consequences of a
hearing loss.
Ross, M., JARA, 1997
McCarthy & Culpepper
The purpose of an aural
rehabilitation program is to focus on
assisting hearing-impaired
individuals in the realization of their
optimal potential in communication,
which is needed in educational,
vocational, or social settings.
McCarthy & Culpepper, AJA, 1987, p. 305
Houston & Montgomery
"…the goal of aural
rehabilitation for the adult is
ambitious – to increase the
likelihood, the level, of
successful communication
over the client’s lifetime."
Houston, K.T., and Montgomery, A.A.
Auditory-visual integration: A practical
approach. Seminars in Hearing, 18 (2), 1997.
JP Gagné
“Aural rehabilitation is aimed at restoring
or optimizing a patient’s participation in
activities that have been limited as a
result of a hearing loss and also may be
aimed at benefiting communication
partners who engage in activities that
include person with hearing loss.”
Gagné JP. Ear and Hearing. 2000, p36.
Arthur Boothroyd, Ph.D.
“Adult aural rehabilitation is here
defined holistically as the reduction of
hearing-loss-induced deficits of function,
activity, participation, and quality of life
through a combination of sensory
management, instruction, perceptual
training, and counseling.
Boothroyd A, Trends in Amplification, 2007, p63.
Aural Rehabilitation
Intervention aimed at minimizing
and alleviating the communication
difficulties associated with hearing
loss.
(Tye-Murray N. Foundations of Aural Rehabilitation
(video)
Audiologic Rehabilitation
“Any activity, method, resource,
technology, and/or device that facilitates
and/or enhances communication and
participation in activities.”
Hanavan, PC, 2010
Conversational Fluency
“…relates to how
smoothly conversation
unfolds”
“the book’s central theme”
Tye-Murray N, Foundations of Aural
Rehabilitation, p2. and preface, p ix.
Hearing-Related Disability
“…a loss of function imposed by
hearing loss. The term denotes a
multidimensional phenomenon.”

ICF (WHO: 2001)
Disabilities is an umbrella term, covering
impairments, activity limitations, and participation
restrictions.
– Thus disability is a complex phenomenon, reflecting an
interaction between features of a person’s body and
features of the society in which he or she lives.
Question
Does “hearing impairment” means deaf, only?
Yes
No
ICF (WHO: 2001)
Hearing impairment is a broad term used to
describe the loss of hearing in one or both ears.
There are different levels of hearing impairment:
hearing impairment refers to complete or partial loss of
the ability to hear from one or both ears. The level of
impairment can be mild, moderate, severe or profound;
deafness refers to the complete loss of ability to hear
from one or both ears.
ICF (WHO: 2001)
Impairment is 'a loss or abnormality of body structure
or physiological or psychological function'
Activity limitation is 'the nature or extent of
functioning at the level of the person'
Participation restriction is 'the nature or extent of a
person’s involvement in life situations in relation to
impairment, activities, health conditions, and
contextual factors’
Health-related Quality of Life is 'the functional effect
of an illness and its consequent therapy upon the
patient.'
Satisfaction is the subjective assessment by the patient
that his/her needs or expectations have been met.
Applying WHO Taxonomy to HL
• Anatomy and physiology: Physical and functional
integrity, including integrity of outer ear, middle ear,
cochlea, neural pathways to the brain, and the brain itself.
A major concern is with the status of the cochlea. With
older patients, integrity of neural structures is important.
• Function: Includes hearing threshold, dynamic range,
frequency range, spectral and temporal resolution, acoustic
pattern discrimination, direction and distance perception,
attention, auditory working memory, processing speed, and
ability to listen in noise.
Applying WHO Taxonomy to HL
• Activity: The use of this capacity—the things one wants or
needs to do with hearing in the real world. Examples
include being alerted by sound, monitoring the
environment, recognizing and localizing events and
deducing their significance, monitoring and controlling
one's own speech, and enjoying auditory experiences. The
activities of most concern, however, are perceiving the
speech of others and engaging in spoken language
communication.
• Participation: The contribution of these activities to daily
life, include social interactions and relationships,
employment, leisure, learning, control, creativity, etc.
ICF (WHO: 2001)
Psychological factors pertains to
attitudes, self-image, motivation and
assertiveness, etc.
Social factors are the viewpoint of
society

1 of every 22 infants has some degree of HL
1/1000 to 6/1000 born with HL
1.3% of children who receive special ed services
were hard of hearing or deaf
• 1 in 25 people under age 45
• 1 in 10 by age 60
– Third most prevalent chronic problem in older persons
• 5% of world’s population, about 360 million
people, including 328 million adults and 32 million
children, have disabling hearing loss

The Joint Committee on Infant Hearing (JCIH)
Year 2000 Position Statement
• The American Academy of Audiology, the
American Academy of Pediatrics, the American
Speech-Language-Hearing Association, the
Council on Education of the Deaf, and the
Directors of Speech and Hearing Programs in
State Health and Welfare Agencies have joined
together to endorse universal detection of infants
with hearing loss.
• The goal is that all infants with hearing loss will
be identified before 3 months of age and receive
intervention by 6 months of age.

Common Etiologies
• Most of the hearing loss is genetic with over 30
autosomal recessive (70-80%), dominant (2330%) and X-linked (2-3%) forms.
• A large proportion (60-75%) of nonsyndromic
hearing loss in children has been localized to
defects in a single gene, Connexin 26 (Cx26) on
chromosome 13q11-12.
– A variety of mutations have been described in this gene
with a 35delG hotspot mutation representing over half
of the defects in Caucasians.
• Recently, other links with deafness and connexin
has been established
