• Cure for hearing loss

What is hearing Test?

• Most hearing loss can be helped through
  medication, surgery or amplification. An ear
  hearing test or hearing evaluation is key to
  maintaining effective communication, ear and
  balance health and overall well-being. Our
  communication with family, friends, educators,
  and coworkers is an essential part of our day.
  Our success and happiness in all situations
  depends on great communication.Early
  identification of hearing loss or hearing
  disorders minimizes adverse effects.

Types of hearing test

• Basic diagnostic audiometry is used to measure
  hearing for frequency-specific tones and speech.
  Based on the age of the patient or their ability
  to respond, various techniques are utilized
  throughout the process. Additional measures allow
  us to determine the overall function and mobility
  of the middle ear.
• 1.AUDITORY BRAINSTEM RESPONSE (ABR TEST)-
  Auditory Brainstem Response testing is useful in
  demonstrating the softest mid to high pitched
  sounds the hearing system can respond to. The
  test takes approximately one hour. Four
  electrodes are attached to the scalp and
  headphones placed in the ears. Clicking sounds
  are presented at various loudness levels and a
  response is measured on a computer. The response
  allows the audiologist to determine how
  efficiently sound is moving through the hearing
  system.

OTOACOUSTIC EMISSION (OAE TEST)

• Otoacoustic emission testing evaluation is an
  evaluation of cochlear function (the sensory
  organ of hearing). OAE is a fairly new but very
  reliable test. A normal cochlea will emit an echo
  when a sound is presented. Earphones are placed
  in the ear canal and a clicking sound is
  presented in the ear. A computer monitors the ear
  for a response, which enables the audiologist to
  determine if the cochlea is functioning normally.
  An OAE evaluation takes approximately 30 minutes.

ELECTRONYSTAGMOGRAPHY (ENG)/VIDEONYSTAGMOGRAPHY
(VNG)

Electronystagmography evaluates the causes of
dizziness, vertigo, or balance dysfunction. ENG
is designed to test the function of several of
the systems involved in keeping us steady and
balanced. Use of electrodes or video goggles to
measure and record eye movements allows for
objective assessment of the oculomotor and
vestibular system.

COCHLEAR IMPLANT EVALUATIONS REHABILITATION

Cochlear implants are electronic devices
surgically implanted in individuals who are deaf
and can no longer benefit from conventional
hearing aid technology. Thorough examinations by
both an audiologist and physician can help to
determine if a person is a qualified candidate
for this type of procedure.

What are Rinne and Weber test

Rinne Test In the Rinne test, air and bone
conduction tests are compared. In normal hearing,
tones sound louder by air conduction than by bone
conduction. In conductive hearing loss, however,
the bone-conduction stimulus is perceived as
louder. In sensorineural hearing loss both air
and bone conduction sounds are diminished, but
the air conduction sound is perceived as louder.
The Rinne test is most sensitive in detecting
mild conductive hearing losses if a 256 Hz tuning
fork is used.

Weber Test
The Weber test may be performed using a 256 or a
512 Hz tuning fork. During this test, the stem of
a vibrating tuning fork is placed on the head in
the midline. If the tone is perceived in
the affected ear, this indicates a unilateral
conductive hearing loss. In the case of
unilateral sensorineural hearing loss, the tone
is heard in the unaffected ear instead.
