Can You Hear This Sound? If Not Then You're Probably Ageing
How Old Are Your Ears? (Hearing Test)
If you can hear all of the sounds in the video above then you're apparently fit as a fiddle in the hearing department.
This is according to asapSCIENCE, an educational YouTube channel by Canadian duo Mitchell Moffit and Gregory Brown.
The video demonstrates how our ears age by playing different pitched sounds - our ability to hear high frequencies decreases with age.
It starts off with an output of 8,000 hertz, increasing to 12,00hz, 15,000hz, 16,000hz, 17,000hz, 18,000hz and 19,000hz.
Watch the video and find out how old your ears are. Who knows, you may even learn something!
