How old is your hearing? Amazing test
How old is your hearing? Amazing test

Here's a cool little test for a Friday.

Obviously I'm not a doctor, so I can't vouch for the accuracy of this, but it's interesting to compare your results with your friends, and get a sense of just how good or bad your hearing really is. Click the button on this website and click again as soon as you can't hear the tone anymore. It'll let you know how your actual age compares to the age of your ears...

Oh, and keep your cats and dogs out of the room... Cats can hear up to 79,000 Hz and dogs up to 60,000 Hz.

Here's another one with the "full spectrum" to try!

Hearing specialists use 'audiograms' like this to investigate hearing loss. The most important frequencies for speech fall between the 250 and 6,000Hz range so as we lose frequencies at either end of the spectrum, it gets more and more difficult to decipher speech. Vowel sounds are typically the low frequencies that account for the louder volumes of speech. Consonants, especially ‘f’, ‘s’, and ‘th’ are higher frequency sounds and more easily missed as we lose hearing.
