3. Importance of Hearing Mechanism
Hearing is the ability to perceive sound by detecting vibrations through
the ear. The ability to hear enables us to connect to the world. Most
importantly, hearing connects us to people enabling us
to communicate in a way that none of our other senses can achieve. It
can be thought of as a biological microphone.
Sound waves enter the outer ear and travel through the
external auditory canal until they reach the tympanic membrane,
causing the membrane and the attached chain of auditory ossicles to
vibrate.

5. Importance Of Hearing Mechanism In
Speech And Language Development
Hearing is critical to speech and language development. Hearing sounds
and words helps children learn to talk and understand. Children pick up
words they hear in their environment. To develop spoken language,
children must be able to hear speech clearly and also to hear
themselves.
If child's hearing loss is left untreated, their basic language
development will often be delayed. A child with hearing loss misses out
on these sounds. This can cause problems with speaking, reading,
school success, and social skills.

6. The earlier a hearing loss occurs in a child’s life, the more serious the
effects on the child’s development. Similarly, the earlier the problem is
identified and intervention begun, the less serious the ultimate impact.
There are four major ways in which a hearing loss affects children:
I. It causes delay in the development of receptive and expressive
communication skills (speech and language).
II. The language deficit causes learning problems that result in reduced
academic achievement.
III. Communication difficulties often lead to social isolation and poor
self-regard.
IV. Having trouble in making friends.
V. Awkward feeling due to behavior of surrounding people.
It is important to have child tested if you think he has trouble
hearing. Getting help early is easy to recover. Children with any kind

7. of hearing loss do not able to learn speech and language as far as
other normal children.

8. Speech
Children with hearing loss cannot hear sounds well. They may have
problems speaking clearly. They may:
 Not use sounds like s, sh, f, t, or k. These are quiet sounds that are
hard to hear.
 Not hear their own voices when they speak. They may be too loud
or too soft. They may speak in a high pitch. People may think they
mumble or sound different.
Causes
 Articulation impairment.
 Fluency impairment.
 Voice impairment.

10. Language
Words
They may:
 Learn concrete words like cat, jump, five, and red. However, they
may have trouble with abstract words like before, equal
to, and shy. They may not use words like the, an, are, and a.
 Have trouble knowing the different meanings of a word. Think
about the word bat. It can mean a flying animal or what we use to
play baseball. A child with hearing loss may not understand these
meanings.
 Fall farther behind children with normal hearing as they get older.
Children with hearing loss do not catch up without help.

11. Sentences
Children with hearing loss may have trouble understanding and using
sentences. They may:
 Understand and use shorter sentences than children with normal
hearing.
 Have problems with more complex sentences. They may not use
clauses in their sentences. An example of a clause is "When I get
home, I will eat dinner." They may not use passive voice. An
example of this is "The ball was thrown by Mary."
 Have trouble hearing word endings, like -s or -ed. They may not
understand or use plural words, like cats. They may not use past
tense, like walked. And possessives, like Bob's, can be hard to hear
or use.

13. School Success
Children with hearing loss have trouble in school. Reading and math
may be the hardest for them. Some facts about hearing loss and school
success include:
 Children with mild to moderate hearing loss may fall one to four
grade levels behind without help.
 Children with more severe hearing loss may not learn past the
third- or fourth-grade level. School support will help them do
better.
 Children with hearing loss do not do as well as children with
normal hearing. The gap between them grows over time. Children
with hearing loss will do better in school if they get help early.
This includes support at home from parents and families.

14. Social Skills
Hearing loss can make it harder to talk with others. Children may not
want to talk or play with other kids. Children with hearing loss may:
 Children with a hearing loss often feeling alone, without friends.
 Unhappy in school, particularly when their socialization with other
children with a hearing loss is limited.

15. Conclusion
The most important thing we can do is to have child's hearing tested.
With early help, child may speak or use sign language as well as children
who hear. An audiologist can test child's hearing. He or she can talk to
us about the best way to treat child's hearing loss. This may include
medical treatment, hearing aids, or speech and language therapy.
‘‘We should not strangely behave with those children
who are suffering from speech and language and any
other problems. We should support and encourage
such people to help them out of those problems.’’
