 HOW WELL DO YOU HEAR? TEST YOUR HEARING: How does normal hearing work?The three parts of the ear anatomy are the outer ear, the middle ear and the inner ear. The inner ear is also called the cochlea. (‘Cochlea’ means ‘snail’ in Latin; the cochlea gets its name from its distinctive coiled up shape.)

Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles) in the middle ear. The last bone in this chain ‘knocks’ on the membrane window of the cochlea and makes the fluid in the cochlea move. The fluid movement then triggers a response in the hearing nerve.

What is tinnitus?
Tinnitus is the perception of noises in the head and/or ears which has no external source. It is not a disease or illness; it is a symptom generated within the auditory system. The noise may be in one or both ears, or in the head, or it may be difficult to pinpoint its exact location. The noise may be low, medium or high pitched. The may be a single noise or two or more components. The noise may be continuous or it may come and go.
Who gets tinnitus?
Experiences of tinnitus are very common in all age groups, especially following exposure to loud noise. About 10% of the UK adult population have permanent tinnitus.
What causes tinnitus?
The causes of tinnitus are still not fully understood, but tinnitus can be associated with:
Hearing loss - the delicate hair cells in the inner ear may reduce in number due to ‘wear and tear’ as people age. This gradual change can cause hearing loss, which makes tinnitus more noticeable as it is not masked by external sound.
Exposure to loud noise - hair cells can also be damaged by exposure to loud noise, which could generate tinnitus.
Stress and anxiety - it is not always clear whether stress causes the onset of tinnitus. However, tinnitus may be more noticeable if you are anxious or stressed.
Ear infections - middle ear infections can cause hearing loss and tinnitus. Symptoms will normally be temporary, but it is important to have the underlying infection treated by a GP.
Treatment options
Tinnitus is rarely an indication of a serious disorder, but it is wise to see your doctor if you think you have it. Your GP will be able to refer you to specialist Ear, Nose and Throat (ENT) and Audiology services.
An ENT specialist will take a medical history from you, perform a clinical examination and arrange for any tests. You should then be referred to the Audiology service for help in managing your tinnitus.
There are several strategies that can be very helpful in managing the condition:
Information - you will probably feel better when you find out more about the condition, that it is very common and that you are not alone.
Counselling - techniques such as Cognitive Behavioural Therapy (CBT) can be helpful, either as a standalone therapy or combined with sound therapy.
Correcting any hearing loss - if your tinnitus is accompanied by any hearing loss, then trying to correct this loss with hearing aids is often very helpful.
Sound therapy - if the noises seem louder at quiet times, particularly during the night, it may help to have some environmental or natural sound from a CD, a sound generator, or even a fan or ticking clock in the background. Some people use in-ear sound generators.
Relaxation - learning to relax is probably one of the most useful things you can do to help yourself. Those who practice relaxation techniques say they reduce the loudness of their tinnitus and helps them become indifferent to it.

Support groups - the BTA can also put you in touch with a support group or contact if there is one in your area. Groups are run by people who are living with tinnitus - personal contact and shared experience are very useful for many people with tinnitus.
Information leaflets - the helpline can also give you details of the BTA’s wide range of information leaflets on tinnitus and associated subjects which are available in standard or large print. They can also be downloaded free of charge from the BTA’s website www.tinnitus.org.uk
It does get better!
Studies have indicated that, over time, the noises disappear completely or at least diminish to a tolerable threshold level in most cases, as the brain loses interest and stops surveying the signal. This process is called ‘habituation’. The length of time this takes varies from person to person - but it does happen.
