A
Audiogram
1. A graphic illustration of hearing sensitivity. An audiogram depicts
hearing levels (in dB) at different frequencies (Hz) of sound.

C
Central
Auditory Processing Disorder (CAPD)
A
deficiency in the way the brain processes verbal/auditory information.
Children and adults that have CAPD often struggle to understand
the meaning of what is being said to them. Some people are born
with CAPD whereas; other people acquire it later in life.
(Is
CAPD curable? Learn more at AchieveHearing.com)
Cerebral vascular accident (CVA)
Also called a stroke. Damage to part of the brain due to a disturbance
in the blood supply.
Conductive hearing loss
Reduced hearing acuity from diminished ability to conduct sound
through the outer or middle ear; often due to abnormalities of the
external ear canal, eardrum, or ossicular chain.
D
Dementia
A loss of brain function that occurs with certain diseases. It affects
memory, thinking, language, judgment, and behavior.
E
Earmold
A fitting designed to conduct amplified sound from the receiver
of a hearing aid into the ear.
Eustachian tube
A tube that connects the nasopharynx and the middle ear. It equalizes
pressure in the middle ear with atmospheric pressure.

H
Hearing
aid
A tiny electroacoustic device which can be fit by an certified Audiologist
in or behind the patients ear, and is designed to safely amplify
and modulate sound to achieve better hearing.

I
Impedance
Resistance to a vibratory source of energy. Resistance may be acoustic,
mechanical, or electric. In impedance audiometry, impedance of air
pressure and air volume differences are measured to detect conductive
hearing loss and middle ear pathology.

M
Meniere’s
disease
A disease of the inner ear characterized by progressive sensorineural
hearing loss in the affected ear, recurrent dizziness, tinnitus,
nausea, and/or vomiting.
Mixed hearing loss
A hearing loss with conductive and sensorineural components.
N

O
Ossicles
The three small bones of the middle ear (incus, malleus, and stapes).
Also referred to as the ossicular chain.
Otitis media
An infection of the middle ear frequently acquired by children and
often associated with upper respiratory infection. There are three
varieties: Acute otitis media: A sudden onset of otitis media caused
by an infection.
Chronic otitis media
The permanent condition of a ruptured tympanic membrane. It may
or may not be associated with infection.
Serious otitis media
Inflammation of the middle ear, with the presence of a thick or
watery fluid that fills the middle ear space.
Ototoxicity
Damage to the ear caused by a harmful poison. It is usually associated
with certain drugs.
P
Pinna
The outside, visible part of the ear. Also called auricle.
Presbycusis
Progressive loss of hearing as a result of the aging process. .
Q

R
Receptive
abilities
The ability to understand or comprehend language. It usually refers
to the ability to understand verbal expression, but it also includes
the ability to understand sign language, writing, Braille, and other
forms of language.
S
Sensorineural
hearing loss
Reduced hearing acuity due to a pathological condition in the inner
ear or along the nerve pathway from the inner ear to the brainstem.
Speech
Therapy
Reduced hearing acuity due to a pathological condition in the inner
ear or along the nerve pathway from the inner ear to the brainstem.
T
Telecoil
switch
A hearing aid switch that allows the induction coil in the hearing
aid to pick up signals from a telephone. It is also use in loop
induction auditory training units.
Traumatic brain injury
An acute assault on the brain that causes mild to severe injury.
The two types of traumatic brain injury are penetrating injuries
and closed-head injuries. The damage is localized or generalized,
depending on the type and extent of the injury.
Tympanogram
A graph depicting eardrum and middle ear compliance measured during
air pressure changes in the external auditory canal.
