We’ve all been warned about losing our hearing for about as long as we’ve loved music. Don’t listen to music too loud, wear earplugs at concerts, turn the bass down in the car… ¯\_(ツ)_/¯

However, the ear doesn’t repair itself—once that hearing is gone, it’s gone forever. So, in the interest of checking in, this video helps you test the age of your ear by playing progressively higher frequencies to gauge how much hearing you’ve got left. If you’re 19 with the inner ear of a 54-year-old, it might be time to turn down the dial. Make sure you take the test with the video streaming at 1080p and with headphones on; I did neither and truly believed I was going deaf.
