Here's an interesting link I found in another forum.
How good is your listening ability?

I scored -39db

I scored -33db

I used headphones and I think that is why I was able to score well. I just tried it with the PC speakers and scored -19db

I first tried it with a pair of cheap Sony headphones,didn't do as well as I did when using a set of Senn 570s.

I just tried it again with the headphones and scored -28db.
Not too bad. My first score must've been beginners luck

Interesting. I tried it on my laptop with Sennheiser HD500s and my favorites, Shure E2cs. I still only made it to -12dB. Too much heavy metal and punk during my teens and early 20s.
