Mosquito Ringtone

Some of you might have read about the super-high pitched Mosquito ringtone. This ringtone, which is of super-high frequency, can be heared by most teenagers but not adults (especially the decaying ones). The principle behind this is that we gradually lose our ability to listen to higher frequencies as we age.

I did some googling, and found a page where some person (with apparently a fair amount of free time) made many samples of the different frequencies. You can test what is the cutoff frequency of your ear (and indirectly how old you are hehe...) here.

Oh yes, you can reference the frequency range to age using this chart here.
