What is age related hearing loss?
Do you know how your ears work? Or Why elder people are hard of hearing ? I went on the world
wide web in order to answer these questions.There are too many results include of blogs, pictures,
videos.I visited one of the most famous blog about ears.Its named Hearingloss blog.The reason why this
blog is so famous is writer Dr.Eric.Mckeeper. Who is well-known audiologist.After I read all articles I
knew about what is hearing loss and how our ears work how can we prevent of hearing loss? and what
is earing aid?
Your ears are very complex organs,and they have to work hard in many ways so that you can hear the
world around you.Your ears split into three sections.Hearing loss is defined as three types.One of them
is related to aging ear.In the end I answered all my questions and learn about How to choose best
hearing aid between a lot of species.
First of all your ears consists of three major areas(Picture 1.1):
1. Outer ear( Pinna)
2. Middle ear
Picture 1.1 Structure of ear
3. Inner ear Your outer ear collects the sound around you and funnels them into your ear canal
which causes your ear drum(tympanic membrane) to vibrate.This vibration shakes the ossicles in
yor middle ear,which helps move the sounds into the cochlea in your inner ear.Your cochlea
processes these sounds and sends them up the auditiory
nerve to your brain,where you interpret what you
hearing.Picture 1.2
Second:Hearing loss is defined as 3 types(Picture 2.1)
1.
Conductive (involves outer or middle ear)
2.
Sensorineural (involves inner ear)
3.
Mixed (combination of the two)
As you can see drug side effects and noise damages are sensorineural
type of hearing loss.Anotherhand allergies and impacted earwax are
conductive type of hearing loss.Genetic disorders and impections are
example of mixed type of hearing loss.The loss of hearing due to aging is classified as a kind of
sensorineural hearing loss that can’t be reversed and can even lead to deafness and distress.According
to the survey in Mongolia has two hundred thousands of people who is deaf and hard of hearing.47
percent of them is naturally deaf,21 % is age related hearing loss(presbycusis) another ones are because
of drug side effects and noise damage etc(Otgontungalag 2017)
Dr.Eric.Mckeeper said that “Aging ear is originated from
external ear larger,ear canal narrows,Eardrum shrinks and
ossicles do not move as freely’“One in three people in the
United states between the ages of 65 and 74 have hearing
loss”( Mayoclinic.org,2017)
According the survey of World Health and Nutrition examination
2011-2012 people of age 60-69 years are more susceptible than
others. Protect your ears. Limiting the duration and intensity of your
exposure to noise is the best protection. In the crowded place, plastic
earplugs or glycerin-filled earmuffs can help protect your ears from
damaging noise. Avoiding noisy environments and repetitive
exposures to loud sounds,Controlling your blood sugar if you have
diabetes,and getting your hearing tested regularly.
Third: What is hearing aid?
All hearing aids use the same basic parts to carry sounds from the
environment into your ear and make them louder. Most hearing aids
are digital, and all are powered with a traditional hearing aid battery or a rechargeable
battery.Small microphones collect sounds from the environment. A computer chip with an
amplifier converts the incoming sound into digital code. It analyzes and adjusts the sound based
on your hearing loss, listening needs and the level of the sounds around you. The amplified
signals are then converted back into sound waves and delivered to your ears through speakers,
sometimes called receivers.(Picture 4.1) If you have sensorineural type of hearing loss you
should choose the ITE(in-the-ear) hearing aids. Because of the size of
the aid, they may fit a more severe loss.If you have mixed type of
hearing loss CIC or Completely-in-Canal hearing aid is better for you
because that one is Small and very discreet; which makes them
perfect for anyone that doesn’t want others to know you are using a
hearing device. At last If you have conductive type of hearing loss
RIC(receiver-in-canal) is more suitable to you. There are less
feedback problems with this style because there is far greater
seperation between the microphones and receivers.
In conclusion our ear consist of three major areas.(Outer ear,middle ear,inner ear)and
hearing loss problems are defined as 3 types (Sensorineural,Conductive,Mixed) Age related
hearing loss is kind of sensorineural type that can’t be reversed and that can lead to deafness
and distress.Age of 45-69 years people should pay more attention their hearing and getting your
hearing tested regularly.Hearing aids won’t return your hearing to normal they can improve
your hearing by amplifying soft sounds.People have to choose carefully what hearing aid is
suitable for their situation.
