Plug a good pair of headphones into your PC and try the following website:|
For me, I could only hear the 50Hz tone, the 20Hz one made a sound, but it was like a fuzzy "flop" noise repeating, not a pure tone.
In the high frequency range, 16KHz was surprisingly really quiet, and I couldn't hear the 17KHz one at all.
I'm quite sure it isn't the headphones, they're the Sony in-ear Fontopia ones that form a seal in your ear. Their sensitivity is 100dB, and frequency range sadly is between 6 - 23,000Hz
That means I've lost 3KHz of frequencies. Not too good for a 32 year old. =(
On the bright side - in a few more years I can buy bargain-bin $1 headphones that will have a frequency response covering far more than the frequency range I can hear. ^-^
