HEARING TESTS @ HNR HYDERABAD
Auditory Steady-State Response (ASSR)
For children who are too young, Auditory Steady state
response is an objective test used for evaluation of their hearing ability. If the screening of the new born indicates possible hearing loss, they are referred to ASSR. The ASSR results can be used to estimate pure-tone audiogram. For the children under 6 months of age, ASSR is performed when they are in natural sleep. In case of older children, sedation is suggested. The results are obtained by analyzing the brain activity when the person listens to the tone of varying pitch.
Newborn Hearing Screening
The hearing test for the newborns should be done by one
month age, preferable before the baby and the mother
are discharged from the hospital. The hearing test for
newborns is called the Automated Otoacoustic Emission. It
takes a few minutes. The screening test helps identify
babies with hearing loss. Early identification of the hearing
loss helps parents get support and necessary advice they
need right from the beginning

Auditory Brain Stem Response Test
The ABR test calibrates the reaction of the parts of the
child’s nervous system to sound. The test helps to
specifically monitor the performance of the hearing
nerves response to the sound. The ABR test is prescribed if
a newborn baby fails the hearing screening test. The test
is also recommended for the older children if they have
trouble with hearing.

Tympanometry
This acoustic evaluation is used to examine the
performance of the middle ear or ear drum and the
conduction bones. The audiologist introduces a small
earphone like device. This device will blow air into your ear.
The audiologist observes the performance of the ear on
the tympanograms. The information on the graph explains
the audiologist the ear drum’s performance, its
movement. The test reveals if there is any damage to the
ear drum, growing infection in the ear, formation of middle
ear fluid, a hole to the ear drum, etc.

Reflex Audiometry
The reflex audiometry or acoustic reflex is a method used
to measure the function of the middle ear. The
measurements are calibrated on tympanogram by
increasing the acoustic pressure in the external ear canal.
Reflex audiometry measures the total resistance a sound
wave encounters when it progresses through from the
middle ear to the cochlear receptor. The measurement is
simple with sophisticated equipment in a quiet room.
