How to look after your ears?
How well do you know your ears?
Ears are really important in our lives.
Ears don't only let us hear but they also keep our balance.
Your ears are really fragile because they can be damaged permanently after an exposure to a loud noise.
Even when you sleep your ears are still listening to every single noise around you just like when you are up. It's just that your brain ignores it.
When you lose the ability to hear you will be deaf for life or need to wear a hearing device for your whole life so take care of your ears.
• Listen to soft music (under 70 decibels).
• If a noise is too loud (more than 85 decibels) get away from it.
• If one of your friends or family member is listening to music or watching the television too loud (more than 75 decibels) warn them about the effects.

Causes of hearing loss or deafness
Don't work with loud (more than 95 decibels) working tools e.g.: drill without ear protection.

Don't go near any sounds that hurt your ears (+/- 95 decibels) .
Don't go to car or motorbike races without ear protections because it is around 100 decibels and you can get hearing damage after 4 hours.
The pinna picks up the sound wave which then travels throught the ear canal. The sound wave then hits the ear drum.

One of the biggest hearing loss causes is age. Most people start loosing hearing capacity from 30-40 years. It gets worse with age. By the age of 80 it is probable that you will have a really bad hearing. The reason of age hearing loss is that the small tiny hair cells on your cochlea get damaged or even die. You still can hear some sounds and it is rather high pitch sounds that you can have difficulties hearing (women or small children voices).
How to overcome hearing loss

Useful tips and information to keep your ears clean
These tiny hairs are divided into two groups. The first one: the outer hair cells make the sound louder and they pitch it.
The second one: the inner hair cells they take all the information from the vibrations and send these to the hearing nerve, it then sends it to the brain and you can finally hear.
This shock creates vibrations which makes the hammer, the anvil and the stirrup move. These vibrations then go to the cochlea. The cochlea is filled with liquid and is covered in lined cells which have thousands of tiny hairs on them.

Check your hearing regularly at a doctor or specialist.
Don't use ear buds because all they do is push the wax further in your ears.
Use some special spray or just a little bit of water and then put the corner of a tissue in your ear canal to dry it.
After a shower if you feel that your ears are full of water you can tilt you head and pull on your pina to open your ear canal so that the water can leak out.
The second cause of hearing loss is when you are exposed to loud noises in your everyday life.
For example if you are a builder or work in a night club.
Also it is also possible that you were born deaf or hearing-impaired.

Nowadays we can cure hearing loss of deafness with technology. These small helpers are called hearing aids. Different types of hearing aids exist, so you can choose
the color and shape you want your hearing aid to be. However you cannot keep a hearing aid for a lifetime specially for kids as the part in the ear can get too small or even dry and crack in which causes the sound to leak out.
These devices are so modern that you can even plug your phone or music player to your hearing device and listen to music.
