No, it means that if no mic in the world can record the mosquitos, they don=

The human reception is different then machines reception (not just the non-

What makes the human different (some call it superior) is combining this=20

Of course there are legions of scientists and nerds working on making machi=
better in these parts too.

Going into psychoacoustics is not really contradicting the "machines can't=
measure it, still it exists". Machines can measure the frequencies the huma=

Which in turn makes most audio people discard frequencies >22kHz light-

doesn't deny the psycho-acoustic effects, it only ignores them for the sake=

Have fun,
