What are the most common types of hearing
loss?
Although there are many TYPES of hearing
loss, the most common type is SENSORINEURAL
(also called "cochlear" or "inner
ear" or "nerve loss"). The
second commonest type is CONDUCTIVE. Other
types of hearing loss include; mixed and
central.
When the problem is in the inner ear, the
most common - sensorineural hearing loss
- occurs. More than 90 percent of all hearing
aid wearers have sensorineural hearing loss.
The most common causes are; age related
changes, noise exposure, inner ear blood
circulation, inner ear fluid disturbances
and problems with the hearing nerve. |

| Conductive hearing loss occurs when sound
is not conducted efficiently through the ear canal,
eardrum or the tiny bones of the middle ear, resulting
in a reduction of loudness of sound. Conductive
loss may result from earwax blocking the ear canal,
fluid in the middle ear, middle ear infection,
obstructions in the ear canal, perforations (hole)
in the eardrum or disease of any of the three
middle ear bones.
People with conductive hearing loss may notice
their ears seem to be blocked. This person may
speak softly because they hear their own voice
loudly. Chewing crunchy foods seems very loud
to the person with a conductive hearing loss and
this person may have to stop chewing to hear what
is being said. All conductive hearing losses should
be evaluated by an audiologist and a physician
to explore medical and surgical options.
To demonstrate a conductive hearing loss, gently
and safely close your ears with your fingers.
This will give you the feeling of a conductive
hearing loss…you’ll feel plugged-up,
and you’ll feel a little hearing impaired.
Interestingly, some people may tell you they don’t
need hearing aids because they ONLY have a 30
decibel hearing loss. However, assuming you have
normal hearing, when you plug your ears with your
fingers, you’ll experience approximately
a 25 decibel hearing loss – and you’ll
quickly realize that even a VERY MILD hearing
loss is quite irritating and disconcerting!
