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.
