How old are your ears? A video from ASAP Science has gone viral with a test of hearing that's hard to resist.
The video cranks up the frequency of a sustained pitch, beginning at 8,000 hertz and matching the frequency with an average age. At the end of the test, you may be patting yourself on the back, thankful for all those rock concerts your parents didn't let you attend.
Or you could be like some of the commenters at the ASAP Science YouTube channel, wondering why they're 17 but their hearing is 30.
Either way, ASAP makes the test entertaining with its trademark bright diagrams and concise explanations. Now we know why we lose the ability to hear higher pitches over time. Tiny hair cells in the inner ear responsible for picking up different frequencies break down over time with the constant barrage of noise and loud sounds.
