Actually the kids are way ahead of us and have been using the high

That's quite nifty... I can sort-of hear the 15.8KHz one (I can hear the
sound, but it's just not as clear as the slower ones), but not the
16.7KHz one - which is slightly better than my age group (assuming the
site's accurate).

My hearing's somewhat shot though (too many rock concerts and pub gigs in
my youth, too many engines and angle grinders as I've got older :-) so
it's nice to know that I can at least still hear the expected frequencies
(what I do find extremely difficult are things such as hearing someone
talking when there's a lot of background noise)

Some of the frequencies quoted are wrong, the sounds seem to be 10 kHz
less than they should be. Also, your computer's sound system might be
less sensitive at higher frequencies.

I can hear the '18.8 kHz' sound via the tichy speakers in my flat
monitor, and I'm 40.


I can hear them all

I'm 92 you know ...
