Also, it's very weird that you can only hear up to 16kHz. that would put you in legally deaf range.
This is so funny. Male, age 23. By these mosquito tones I can hear all the way up to 22kHz. But when I start Adobe Audition and generate sweep tone 20 to 22 khz in 32/96 mode I can only hear up to 16kHz. that means this test is horse ... well you know what. Of course lower registers doesn't matter because ppl till old age are able to hear bass. You can say that my rig and headphones are crap an you will be damn right, but still. I think you can measure your hearing only with precise signal generator and reference quality rig and HP or specialized equipment, good luck!
