T3 Prescreening
1
Prescreening Learning
Objectives
Recognize normal auditory development.
Understand the importance of early
identification of hearing loss.
Know when and how hearing screening is
conducted.
Practice selecting an appropriate screening
method.
Be able to set up a hearing screening
program.
T3 Prescreening
2
Screening Programs
Goal: to quickly and efficiently
distinguish those children who need
further evaluation from those
children that probably are not
having hearing difficulties significant
enough to interfere with learning.
T3 Prescreening
3
Early Screening in Infants
Otoacoustic Emissions (OAE)
Auditory Brainstem Response (ABR) or
Brainstorm Auditory Evoked Response (BAER)
T3 Prescreening
4
Risk Factors for Hearing Loss

Birth weight less than 3 ½ pounds (1500 grams)
Difficult birth or delivery affecting baby’s breathing
Unusual appearance of head, face or ears
Severe jaundice requiring a blood transfusion
Infection of the brain
Prolonged mechanical ventilation
Characteristics related to certain syndromes
Receiving drugs toxic to the ears

Factor(s) from the previous slide
Factors associated with progressive hearing loss
(infection, mechanical ventilation, heredity)
Parent or caregiver is concerned about hearing,
speech, language or developmental delays
History of head trauma

Child is 16 years or over
Child’s parent objects in writing to the

1. Fluid or drainage from the ear
2. Blood
3. Open sore
4. Foreign object in the ear canal

ADHS Approved
Screening Methods
Pure Tone
Tympanometry
Otoacoustic Emission (OAE)
T3 Prescreening
11
Pure Tone Screening
Can the child:
Attend to sound?
Follow directions?
Give a behavioral response?
T3 Prescreening
12
Pure Tone with Conditioned
Play Audiometry (CPA)
Requires child be able to wear headphones
and learn a play activity in response to
sounds
Is useful with 3-5 year olds
Is useful with children developmentally able
to tolerate headphones and learn a repetitive
task, but unable to follow complicated
directions or stick with a task
Is useful with older children who are
developmentally delayed
T3 Prescreening
13
Tympanometry
Looks for fluid in middle ear
Does not measure hearing
Is useful with young population that has high
incidence of middle ear fluid
T3 Prescreening
14
Otoacoustic Emission (OAE)
Is mostly used with very young or difficult to
screen children
For school age children, must complete pure
tone screening first
Looks for middle ear problems and hearing
loss caused by damage to cochlea or
sensorineural hearing loss
Is quick
T3 Prescreening
15
Selecting the appropriate
screening method depends on:
Age of the child
Abilities of the child (developmental age)
Availability of trained personnel
Availability of equipment and other resources
Ability of the child to follow instructions
T3 Prescreening
16
Selecting a
Hearing Screening Site
Is it quiet?
Are there enough outlets?
Are noisy conditions limited?
Is area adaptable to traffic flow?
Adjust your environment; never adjust
your equipment!
T3 Prescreening
17
Preparing the Hearing
Screening Site
Decide on the number of stations
Obtain a table, 2 chairs & screening equipment for
each station
Design traffic flow
Designate areas for screening and waiting
Obtain extension cords, 3 prong adapters, power
strips & duct tape
Set out necessary paperwork and pens
Set out headphone cleaning supplies
Have “Quick Kit” on hand
T3 Prescreening
18
Quick Kit
Several pairs of latex gloves
Paper towels
Self-closing plastic bags (e.g., Zip-loc ®)
Moistened towelettes, or waterless
handwashing gel
Small bottle of freshly-made bleach and water
solution mixed in a ratio of 1 part bleach to
10 parts of water - Keep this solution out of
the reach of children!

Think, Pair & Share
Activity
Be familiar with state rules
Know your equipment is calibrated
Be sure you use the right screening method for each
