Can you hear THIS? Musicians high frequency hearing test | NoiseAddicts music and audio blog

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 15Hz, so this will help you find out where your high frequency hearing cuts off.

isn't the upper limit of audibility 20kHz? anyway, i can hear up to 20kHz, just barely.

I can hear 18kHz easy... 19 sounds like I hear a bit after the click and it immediately drops off... 20 sounds like there is a low buzz on the track... I'm guessing I'm not actually hearing the 20kHz sound... I was a drummer for 6 years... seems like I should have lost more hearing than that.

I can't hear the 19 kHz tone but I choose to blame my PowerBook's ancient speakers.
