wel i think they have been fooling you
. children can hear up to 19/20 khz when there
around 10 years old adults can hear up to 16/17 khz if you are lucky.
you can test it with a signal generator, slowly sweep the freq. go as hi as you can.
and stop when you can't hear the signal no more. and look at the generator !!!
you'l be suprise'd. there are also web sites for testing your hearing.
ps: the speaker has to go as far as 20hkz.
and lookout for your hearing you only got 2 ears and they dident come with spares.
i think its the same trick like with the mic pre's .( harmonics ) they add more air to the signal.
