welcome to question of the day Friday
where i answer your hearing healthcare
and audio technology question
what is sensorineural hearing loss? today
i'm talking about sensorineural hearing
loss and the inner ear
there are three parts of the ear: the
external, middle, and inner ear
there's also three types of hearing loss:
conductive, sensorineural, and mixed
sound is collected by the external ear
sent down the ear canal to the middle
ear (where the ear drum and ear bones are located)
and then this sound energy is
transferred into the inner ear
the inner ear includes the cochlea and
semicircular canals
the cochlea contains our hearing sensory
cells and the semicircular canals
contain our balance sensory cells
the inner ear contains fluid that moves
in response to sound
this fluid movement activates our
hearing sensory cells called hair
cells which sends signals up the
auditory nerve to the brain
once that signal is received by the
auditory cortex in the brain we perceive sound
so up to this point i've discussed
how the ear works normally
but what happens if we have
sensorineural hearing loss?
sensorineural hearing loss occurs in the
inner ear and it's permanent
it can be caused by damage to the hair
cells inside the cochlea
or by damage to the auditory nerve
sensorineural hearing loss may be the
result of gradual hearing loss due to
aging
also known as presbycusis,
genetic abnormalities,
ototoxic medications,
noise exposure,
an auditory nerve tumor,
illness or disease affecting the inner ear,
head trauma, or congenital causes
sensorineural hearing loss often
appears in the high frequency sounds
first
this makes words sound like they're
garbled or reduced in clarity
hearing aid use is the only way to
provide more clarity
but it's important to know that hearing
aids only aid our hearing they cannot
fix our hearing
and they cannot restore our hearing
fully
in cases of more severe hearing loss
hearing aids may not provide enough
benefit
so a cochlear implant can be considered
cochlear implants stimulate the auditory
nerve with electrical impulses
that the brain interprets as sound
this direct connection to the nerve
bypasses the damaged part of the ear
altogether and sends the signal
up to the brain
remember sensorineural
hearing loss is permanent
avoid excessively loud noise and music
because this can damage your ears
or at least use hearing protection when
you're in those loud situations
So for today's question, what one thing did
you learn about hearing loss or the ear
that surprised you the most?
