10 interesting facts about ears - this selection of facts came across.
1. Do men hear worse?
Men are more likely to experience hearing loss than women. And they don't have an additional filter, as many assume. It's just that they are more often involved in noisy professions and this often damages their hearing.
2. Loud music and your ears
Music is not harmful to the ear, problems only begin when it comes to loud music. Loud music is a problem not only in clubs and pubs, but also in your headphones. By the way, listening to music through headphones increases the number of bacteria by 700 times.
3. The ears are a self-cleaning organ
The ears are self-cleaning. The pores in the ear canal produce earwax, and small hairs called cilia push it out of the ears. If you use the headphones incorrectly, you can damage your ears.
4. Dangerous decibels
The slightest sound you can hear is 0 decibels. The loudness level of the jet engine is 120 decibels, and the volume of the rifle shot is 140 decibels. Exposing you to 90 decibels or more for 8 hours can damage your hearing. Anything over 140 decibels causes immediate damage.
5. Hearing loss is common
About three out of five people aged 60 and over experience hearing loss to some degree. And 40 percent of these people will need a hearing aid.
6. The sound of the ocean in a shell
The sound of a raging ocean that we hear when we put a seashell to our ear is not the ocean, but the sound of blood running through the veins in the ear.
7. Children often have ear infections
Water trapped in the ear can cause hearing loss. This is most common in children and can cause a painful ear infection. It is easy to cure but cannot be ignored.
8. Hearing and balance
Your ears play an important role in keeping you balanced. Next to the cochlea are three sequential channels that act like a gyroscope to keep us in balance and give us information about where you are in space. So with an ear infection, some people have difficulty balancing.
9. Sports and the mutilated ear
Rugby players often have a cauliflower-like pinna. This occurs when the outer cartilage of the ear, which contains no bones, is repeatedly damaged.
10. Child's hearing
Children have more sensitive hearing. At birth, the human ear is able to hear the lowest sound at 20 hertz (which is lower than the lowest sound of a piano) and the highest at 20, 000 hertz.
