Is there something wrong with my ears or it should be like > this? That is quite normal It is in fact good hearing (although many kids can hear up to 22-25 kHz). And it will get worse, especially if you like listening to music on your headphones. Almost all headphone users have their headphones cranked up WAY to loud, and that destroys the nerve cells in the ear. A bus, going up a hill, has sound levels inside of the order of 80dB and in order to hear the music people crank up their heaphones to 90 or 100 dB. After only a few years of that your threshold will be down to 14kHz then 8kHz then 3kHz. With any luck you will effectively be deaf by the time you are 40, and can join the ranks of almost all rock musicians. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
