Can you hear this?

We got a lot of positive feedback on our "Can You Hear Like a Teenager? " article, and it inspired us to take it just a little bit further.
Here is a list of tones that go from 8Hz all the way up to 22,000Hz. It’s fairly common for people who are over 25 years of age to not be able to hear above 15kHz, so this will help you find out where your high frequency hearing cuts off.
Musicians have a much higher risk of hearing loss that most people do, and many of us don’t really wear proper hearing protection. Even just listening to an iPod for an extended period of time can permanently damage your hearing. We also gradually lose our high-frequency hearing as we age.
Take our unscientific hearing test: listen to each of these tones and let us know where your hearing cuts out:
