Title: The Process of Hearing and the evaluation of hearing loss
1The Process of Hearing and the evaluation of
hearing loss
2A child learns by hearing. Like the other four
senses, hearing is essential for an everyone. The
process of hearing starts with the sound waves
entering the external portion of the ear then
channeling through the auditory canal which is
structured like a tube. It has tiny hairs and
tiny glands which make wax inside the ear. Middle
ear starts where the auditory canal ends. Here
lies the eardrum three tiny bones known as
hammer, anvil and stirrup. Sound waves vibrate
and move the hammer, which in turn moves the
anvil. The vibration is then transmitted to the
inner ear through the movement of the stirrup.
3The middle ear amplifies the sound and any
disorder here may lead to hearing loss. The inner
ear is constituted of cochlea and the nerve of
hearing. Sound waves are converted to nerve
impulses here, and sent to the brain by the
movement of miniature cells of hair. Brain
interprets the impulses and makes you to hear and
understand the message sent to you by the
speaker. In case of any kind of distortion,
disruption or disturbance in the whole process of
hearing, hearing loss will be causes.
4Triangle Hearing services include evaluation of
diagnostic hearing for different ages, emission
of otoacoustic, supply, consultation, repair and
fitting of hearing aids, immittance testing for
mobility of eardrum, assertive devices for
listening, frequency modulated system, diagnosis
and treatment of tinnitus, evaluation of CAPD,
swim plugs devices for protection of earmold
hearing and earbuds for iPods and MP3 players.
You can get any kind of services or accessories
related to hearing aids NC.Proper hearing needs
to be ensured from a very early stage. In case
you observe any kind of deviation in hearing with
your children, you can opt for triangle hearing
services for evaluation of pediatric hearing.
5Techniques through which the hearing loss could
be evaluated for proper remedial measures
- Otoacoustic Emissions evaluates the functioning
of the outer hair cells - Visual Response Audiometry(VRA) is applied for
determining the hearing propensity of the child - Conditional Play Audiometry(CPA) evaluates
response of the child to different frequencies
and intensity of sound - Conventional Audiometry(CA) determines childs
hearing levels - Basic Immitance Test Battery evaluates the
response of eardrum to sounds - Auditory Processing Disorder or APD is best
applicable to school-going children who exhibit
problem in hearing and learning.
6Evaluation of hearing loss with adults could be
conducted by a number of testing procedures such
as Pure Tone Audiometry measures ability to hear
at various pitches and volumes, Word Recognition
Testing evaluates the ability of understanding
and responding to speech, Basic Immitance Test
Battery evaluates the response of ear drum to
sound and detection of fluid in the middle
ear.Tinnitus is a kind of ringing or roaring
sound, generated internally. This may annoy or
even incapacitate you. It is caused due to
neurological changes in the auditory system. For
