2. Early identification of a hearing
impairment increases the chances for
the child to receive early treatment
and special education intervention.
The assessment program includes
audiological evaluation, test of mental
ability, and test of communication
ability.
3. 1. Audiological Evaluation
Audiology is the science of testing and evaluating hearing ability to detect and describe hearing
impairments.
Audiological evaluation is done by an audiologist through the use of sophisticated instruments and
techniques. The audiometer is an electronic device that generates sounds at different levels of intensity
and frequency. The purpose of audiological evaluation is to determine frequencies of sounds that a
particular person hears.
Pure tone audiometry utilizes pure tones in air and bone conduction tests which yield quantitative as
well as qualitative description of a child's hearing loss.
Another audiometric test is speech audiometry which uses speech instead of pure tones. Here, the
person's detection of speech at the minimum audible level is measured. The understanding of speech
sound and the ability to discriminate different speech sounds under sufficient loudness are also
determined.
There are alternative audiometric techniques for hearing evaluation such as the sound field audiometry,
evoked response audiometry, impedance audiometry, play audiometry, operant conditioning audiometry
and behavior observation audiometry.
In the Philippines where formal audiological services are limited, informal tests of hearing are employed.
The procedures for some of these hearing tests are described below.
5. Informal Hearing Tests
a. Whisper test
Sit the child comfortably. Ask him or her to stick the tip of the forefinger in
one ear.
The tester sits behind the child where the uncovered ear is. After a deep
breath, whisper some familiar words that contain high pitch and low pitch tones
right behind the unblocked ear. The child must be able to repeat the words
correctly.
6. b. Conversational live voice test
Keeping the same position but facing the child, ask him or her to repeat
words that contain high and low pitch consonants. Start with a whisper and
increase the intensity up to 20 dB moving away from the child little by little. If the
'child hears at a distance of 3 to 6 meters hearing is normal. If the child can
repeat the words but speech is unclear, he or she might be hard of hearing.
C. Ball pen click test
Use a retractable ball pen and place it one inch away from the ear. While
the other ear is blocked by a finger, press the button of the ball pen down and
release it. Do it only once. The child indicates that he or she hears the click by
either raising one hand or acknowledging it with a yes or a nod.
7. 2. Cognitive Assessment
The assessment tools that measure intellectual
capacity of children with hearing impairment do no rely
primarily on verbal abilities. ln the United States, The
Hiskey- Test or Learning Aptitude, the Wechsler
Intelligence Scale for Children (WISC) and the
Stanford Achievement Test (SAT) are widely used
because of the nonverbal performance subtests.
8. 3. Assessment of Communication Abilities
Assessment of speech and language abilities includes an analysis
of the development of the form, content and use of language.
Articulation, pitch, frequency and quality of voice are examined.
4. Social and Behavioral Assessment
Hearing impairment brings about significant effects on social-
emotional and personality development as a result of the restrictions
in interactive experiences and communication activities with their age
group. Linguistic difficulties oftentimes show in low self-concept and
social-emotional maladjustment.
9. Interpersonal Relation
• it has something to do with close, deep or
strong association or acquaintance between
two or more people that may range in
duration from brief to enduring: a bond or
close association that exists between two or
more people who may share common
interests or goals (Juneja, n. d).
10. - is a relationship
characterized by love,
intimacy, trust and respec
between individuals and
might end up in marriage;
Love
11. Communication
- refers to the exchange in meanings
between individuals through a
common system of symbols, signs,
behavior.
