How
Hearing is Tested in Children
-
Auditory
Brainstem Response (ABR):
While a child is sleeping or sedated, electrodes are placed
on the child's head, sounds are presented through earphones
and changes in brain wave activity are monitored when sound
is presented.
-
Otoacoustic
Emissions (OAE): involves
placing a small probe in a quiet child's ear and measuring
activity of the cochlea (inner ear).
-
Behavioral
testing: An alert infant or toddler sits on a parent's
lap in a sound proof room while an audiologist presents various
sounds and monitors the child behavior in response to sound.
Visual Reinforcement Audiometry can be performed when a child
is old enough to turn to the direction where a sound originates,
and the audiologist reinforces responses with animated toys
and lights.
-
Tympanometry
involves placing a special soft camera in a child's ear to
evaluate middle ear function.
