This is a sound that can only be heard by people under 20 (some over 20 can hear it but not many) - it is a sine wave at 18,000 Hz (by comparison, a dog whistle sounds at 16,000 - 22,000 HZ - meaning your dog can hear this “under 20s” sound as well). This sound is used by some teenagers as a ring tone on their mobile phone so that only they (and others of their age group) can tell when the phone is ringing. It is also occasionally used in England to play very loud in areas that authorities don’t want teens to congregate in, as the noise annoys them. As people get older they lose the ability to hear higher pitched sounds - that is the reason that only young people can hear this sound - it is too high for most people over the age of 20.

hahaha I'm 15 and I can hear it but my mom's 42 and she can too. I guess the 20 and below isn't 100% and some older people can still hear if their hearing isn't as bad as most.
