And it will get worse, especially if you like That's the main reason why I asked - I heard that people can hear 22khz or about that when they are young, than listening gets worse and they don't hear very high frequencies anymore - and since I consider myself still young ;), I was kind of disappointed by the fact that I can't hear not only 22khz, but even 20khz, and when I discovered that I can't hear even 18khz, I was kind if scared - is my hearing going down due to headphone usage?

After only a few years of that your threshold will be down to Actually there are solutions, like good in-ear noise isolation headphones, for example ER6 and ER4 are pretty good (though expensive) - http://www.etymotic.com/ephp/er6.aspx, with background isolation over -30dB.
