WHOA! Science Facts You Didn’t Know Were Real

There Are Certain Frequencies Only Kids Can Hear

Daily Mail

As we age, we lose the ability to hear certain high-frequency sounds, due to a process called presbycusis. It basically just boils down to the natural aging of the cells in our ears, so rest assured it’s nothing to worry about. Because of this process, there are certain sounds that only younger people are about to hear. Try it out for yourself, by inviting your kids to take this test with you. Some businesses have used this phenomenon to develop controversial devices that emit high-frequency noise in an attempt to keep kids from loitering. Kids have cashed in on this fact as well, however, and often use these frequencies as ringtones when they’re at school.
