If you are someone who likes to change your cell phone ringtones, you might probably have heard this unique ringtones. It is ringtones which are designed to be audible for specific age range. For example, if you download one of the ringtones below which are made for 18 years old or younger, only people within that age range can hear it.
Basically, it is based on the fact that human hearing are less and less sensitive when he/she became older. Research found that people who are 18 years old or younger still can hear a sound with frequency around 22kHz. This frequency sensitivity decreases as people gets older. And if you still can hear ringtones which are intended for people below your age, that means your hearing is excellent!
Try these ringtones (in mp3 format) to test your hearing or if you want to make your cell phone rings unnoticeable by your parents :-)

I could not hear anything, even for everyone. does it mean that I am deaf?
There might be a problem with your speaker, you can try turning your speaker volume up.
Other alternative may be by trying to download the file and play it using a Media Player.
