Want to know how old your hearing is? The boys from AsapSCIENCE developed the handy test above to help you find out.
But before you get started, it's important to watch the video in 1080p and use headphones (good quality ones, if possible) to get accurate results.
Got that sorted? Good. So how does it all work? As we get older, we slowly stop being able to hear sounds at the extreme ends of the hearing spectrum. This is because the inner-ear cells that detect sound waves, nerve cells called "hair cells" begin to die off, and they don't regenerate.
The hair cells that pick up the highest frequencies are the first to receive sound waves in your inner-ear, so that means that they're also the first to become stressed and stop working as we age (or as we're exposed to a lot of loud music).
So, while pretty much everyone can hear frequencies of 8,000 Hz, most people over the age of 40 can't hear 15,000 Hz.
Note that YouTube has compressed this video so, unfortunately the 19,000 Hz frequency has been lost. But that doesn't matter to me because I didn't come anywhere close to being able to hear it. Sigh.
Go and watch the video above to find out how young (or old) your ears really are and prepare to be depressed.
