Bloody hell, that's odd in a sinister way. Today in the morning i decided to pass another hearing test (using sound forge generator) and found out that my left ear hears nothing over 10,5 k. And hears some 2 db worse than right. Right is ok - I can hear 16 k. I knew that my left ear is a bit lowpassed, but 10,5 k was like "I can use is as the fizz remover plugin". Shitty.
And now the hearing test is on this forum. AAAAARRRGHHHHH
