I think you're hearing the movement of the elements. I find it makes a similar amount of 'noise' compared to Canon USM focusing lenses....very very quiet, and essentially no focus motor noise (which I view as silent AF), but you can still hear the elements move a bit...I mean, the elements do need to slide along the lens barrel.
Maybe I'm bad at describing the sound but no, this is not like sound from the Canon USM lenses, or the Sigma HSM. What you here from them is more like a smooth whooshing sound, not a high pitch whirring sound.

A gyroscope? It's an ordinary lens Carsten, I don't think there is a gyroscope involved and it is not about the sound made by the IBIS - this is lens related and to this lens only.
IBIS, that is what I meant Oh well.
No problems Carsten, any suggestion is welcome.
I got a reply from a user at another forum suggesting he can hear the same when lifting the lens up tp his ear and let the camera focus at something impossible; a whirring sound but very faint. My reply to him:
A high pitch whirring sound" - that's it. In my case it is clearly audible in all situations, shooting with the camera lifted, from the side when my wife handles the camera or when standing in front of it. I'll visit the shop again and compare it to their demo copy.
