How Old Are Your Ears

How Old Are Your Ears , is a short video (which needs to be watched in 1080p for accuracy since youtube applies its own compression) which plays a series of high frequency tones which you may or may not be able to hear, and explains why that is the case. (This is why perceptual codecs like MP3 generally throw away frequencies over 16kHz since a large portion of the population will not be able to hear them anyway)
