Hearing Loss: You may not know what you are missingThere are
over 8 million people in the United Kingdom, who suffer with hearing problems. most of
these people are not completely deaf, but "Hard of Hearing"
Unfortunately hearing loss can go undetected for many years, as the symptons are often
ignored or confused i.e other people not speaking clearly.
Sometimes the cause of a hearing difficulty is nothing more sinister than ear wax,
blocking the sound pathways, and can be cleared quite easily by your Doctor or practice
nurse.
In reality we now live in a very hectic world and the stress and strain on ones hearing
can be tremendous. Our history of working in noisy surroundings has inevitably left its
mark, as does the fact that as we get older there will obviously be some degeneration of
the nerve endings which enable us to hear clearly.
The Ear
The ear responds to the vibrations that constitute sound, and these are translated into
nerve signals and passed to the brain. The ear consists of three parts: outer ear, middle
ear, and inner ear. The outer ear is the sound collection point, which directs the sound
down the ear canal towards the ear drum (tympanic membrane). Sounds vibrate this membrane,
the mechanical movement of which is transferred to a amaller membrane leading to the inner
ear by three small bones, the auditory ossicles.
Vibration of the inner ear membrane move fluid contained in the snail-shaped cochlea,
which vibrates hair cells that stimulate the auditory nerve connected to the brain. Three
fluid-filled canals of the inner ear detect changes of position; this mechanism, with
other sensory inputs, is responsible for the sense of balance.
When a loud noise occurs, muscles behind the eardrum automatically, suppressing the
noise to enhance perception of sound and prevent injury.
Hearing Loss
As was said previously, there are over 8 million people suffering with some form of
hearing loss, many of which are suffering with a sensori-neural hearing loss (nerve
deafness) This type of loss means that whilst the person can hear quite clearly when
listening on a one to one basis, any background noise or poor acoustics (cocktail party)
can interfere with ones perception of what is being said, leading to a lack of clarity in
the sounds being heard. Difficulty hearing on the telephone, family converstions and
softly spoken voices, can lead to a feeling of isolation.
Hearing Health Checks
It is advisable as you would with either a Dentist or Optician, to have your hearing
checked on a regular basis, this can be done free of any charge, either by your G.P. or
local E.N.T hospital or by a Privately registered Hearing Aid consultant. They will be
able to give you advice, should you need to consider a hearing aid. Please be assured that
you will not be offered a hearing aid, unless you need one.
Hearing Aids
When considering a hearing aid, there are basically two choices, firstly one provided
by the government via the N.H.S. They are free of charge, but in the main
quite old technology, and sit behind the ear with a tube connected to an ear
piece, designed to fit the shape of ones ear. However, in 2000 the
Government announced a project to introduce digital hearing aids into the
NHS. You can read about the project by clicking
this link.
Alternatively you may seek out the advice of a Registered Hearing Aid consultant who
will be able to demonstrate to you the benefits of Digital Hearing aids and explain to you
which type is best suited to your requirements. See: www.21stcenturyhearing.com
The Digital Leap
With the introduction of digital hearing aids, it became clear that a digital hearing
aid could provide the user with a range of benefits never previously possible in a hearing
aid. Clear comfortable sound reproduction without internal noise and an efficient
management of feedback whistle. Added to this is the automatic regulation of sound volume,
giving comfortable adaptation to the various sound environments encountered in every day
life. The result is a hearing instrument, which has made the greatest contribution to
increasing speech understanding, even in noisy surroundings.
