The Hearing Process
Brain translates impulses caused by
sound waves into meaningful messages.
 Allows communication through the
“telling-listening” process.
 Facilitates sharing of ideas and
emotions, and membership in
mainstream society.

People Who are Deaf..
Profound hearing loss
 Very little, even with aids
 Restricted ability to communicate
 Feel part of cultural minority—the Deaf
culture

Three Groups
Congenitallly Deaf—present at birth
 Prelingually Deaf—occurs before language
development
 Postlingually Deaf—occurs after age 2 or
language development

Types of Hearing Loss
Conductive Hearing Loss—loss in the
outer/middle ear
 Sensorineural Hearing Loss—loss in the
inner ear
 Mixed Hearing Loss—both
sensorineural and conducive

Degree of Hearing Loss
Mild—hear some speech sounds but soft
sounds are hard to hear
 Moderate—hear almost no speech at a
normal level
 Severe—hear no speech at a normal level
and only some loud sounds.
 Profound—will not hear any speech and only
very loud sounds

Degree of Hearing Loss

Degree of hearing loss refers to the severity
of the loss.


Unilateral or Bilateral—One or both ears
Pre-lingual or Post-lingual—Before language
acquisition or after
Symmetrical or Asymmetrical—Same or
differing degree and configuration of hearing
loss in each ear
Progressive or Sudden—Becomes worse over
time, or happens quickly
Fluctuating or Stable—Changes over time, or
sometimes getting better, sometimes getting
worse
Congenital or Acquired/Delayed Onset—At
birth or develops later in life
Causes
Maternal Rubella
 Meningitis
 Heredity
 Noise
 Head trauma
 Malformation of the inner ear
 Impacted ear wax
 Fluid in middle ear (from colds)
 Punctured eardrum

Prevention
Protect your ears—turn volume down to
music
 Early diagnosis—have your hearing tested
 Avoid recreational risks—wear hearing
protectors or take breaks from loud activities

Tests and Diagnosis
General Screening Tests—Dr. speaks at
various volumes to see how you respond
 Tuning Fork Tests—Metal instrument that
produce sound when struck
 Audiometer Tests—Earphones are worn to
hear various ranges of tones directed to one
ear at a time

Treatment
Removing Wax Blockage—Dr. may
loosen it with oil, then flush, scoop, or
suction the softened wax out
 Hearing Aids—makes sounds stronger
and easer to hear
 Cochlear Implants—amplifies sound and
directs it into ear canal; compensates for
damaged or nonworking parts of the
inner ear

Cochlear Implants

Cochlear implants use
an external
microphone and
speech processor that
you generally wear
behind your ear. A
transmitter sends
radiofrequency signals
to a surgically
implanted electronic
chip, the receiverstimulator, which
stimulates the auditory
nerve with electrodes
that have been
threaded through the
cochlea.
Strategies for Inclusion
Can be misdiagnosed with behavioral
problems
 Attention span is shorter
 General education may be MOST
restrictive environment
 Much emphasis placed on reading

Communication Tips
Gain attention
 Don’t shout
 Rephrase when misunderstood
 Moderate pace, not slow
 Use facial expressions and gestures

Implication for P.E. and Sports
Learn basic signs—stop, go, freeze, line up,
wait, or yes and no
 Visual Timer—visual countdown for activities
performed in time increments
 Visual Stick—Pictures/symbols for the days
activities
 Use colored jerseys to distinguish teams
 Use visual cues for changing stations
 Provide a helmet for the necessary activities
