Don’t you just love misleading pictures?

It’s all about the hearing these days. I remember those crazy sound-tests when I was a little kid. They put these enormous headphones on you, and told you to raise your hand whenever you heard something. Fun at first- but simply annoying after listening to high-pitched frequencies for a full ten minutes. I remember going back to class with the ringing still in my ears.

Little did I know that I was hearing frequencies most adults probably could not of. According to research, children and young teenagers can hear higher frequencies then adults. Well, a shopkeeper in Wiltshire, England has decided to utilize this information. The man developed a mosquito-type noise that plays outside of his shop to keep away troublemakers. Apparently, the noise is unbearably annoying for anyone under the age of 25. You can even try listening to the soundwave yourself.

(Something to note about the BBC article above: The caption on the picture of the mosquito reads, “A Mosquito, yesterday”. Whatever happened to pictures actually relating to the articles?)

Anyways, someone who noticed this article decided to create a sample of different frequencies to test their own hearing. Test it on their website for yourself. See how high up you can get before you can’t hear anything at all! The highest I can hear is 17,000 Hz- and I challenge you to beat it.

(Note: Try this around animals for extra fun :D)
