I'm 32 and I can hear those 18khz test tones without any trouble... I once had really awesome hearing range, I could tell when the telly was off downstairs just by hearing the high-frequency power whine on the transformer.
duno if playing loud music affects the fq ur ears can hear or if its just age, but thought its intresting i can hear 17 but not 18!
can hear all of em!
I could hear all of them apart from 18...........
I can hear the lot but surely it depends what volume you have your headphones on
For example I have Technics rp dj1200 cans on volume 3. What if people have got there volume on 100, or have the bass up in their computer sound bit or something cus then it makes the test a little un reliable.
