How Old Are Your Ears? (Hearing Test) - YouTube


When doing a hearing test, it is recommended that you select "1080p" of image quality from the setting icon when watching movies on YouTube, and wear headphones to do it.


That's why I started the movie. The movie starts from the question "How old is your ear?"


It is a feeling that the tests are executed in parallel while drawing letters and illustrations by handwriting on the white board.


First of all, the sound of 8000 Hz targeted for all ages flows.


Next, the sound of 12,000 Hz, that if it can hear it is the ear age under 50 years old.


People who can hear the sound of 15,000 Hz are owner of younger ear age than 40 years old.


The sound becomes more difficult to hear quickly, but if you are 30 years old or younger, you can hear the sound of 16000 Hz.


When it hears this, the ear age is 24 years old or less, that is, the sound of 18,000 Hz.


The sound of 19,000 Hz can not be listened to by YouTube video compression.


This concludes the test.


In the first place, the mechanism to "hear the sound" is in the earsHair cellsReceive vibration of sound ...


By sending it to the brain as an electric signal, it recognizes the sound.


But hair cells are gradually damaged by continuing being exposed to sound. Because of this damage hair cells can not feel the vibration of the sound, hearing ability will decrease.


Furthermore, in the part near the entrance of the earHair cells for receiving high frequency soundAnd these hair cells are susceptible to more damage because they are exposed to more sounds.


That's why it seems that it will be difficult to hear high frequency sounds as years go by.


Easily check the age of your ear, so if you overwork your own ear, once you try it you will be able to strike the result of the impact ....
