Altså er det katten og ikke hunden vi burde spørre om hirez kilde og superdiskant fungerer bra ;-)

I hvert fall ikke høns...

Kanskje SACD blir en slager når bare dyrehagene får ut finger'n

Litt interessant at tunfisk og beluga som begge lever i havet har så radikalt forskjellig frekvensområde?

64-23000hZ ?? trodde da vi hørte betraktelig lavere frekvenser enn det.

http://en.wikipedia.org/wiki/Psychoacoustic_model

"The human ear can nominally hear sounds in the range 20 Hz to 20,000 Hz (20 kHz). This upper limit tends to decrease with age, most adults being unable to hear above 16 kHz. The ear itself does not respond to frequencies below 20 Hz, but these can be perceived via the body's sense of touch. "

Jeg ville nok ha festet størst lit til wikipedias tall i dette tilfellet.
