Why not test for yourself

Take some handheld shots at 105mm at slow shutter speed (1/30s to 1/8s) with OS off and on and see the difference.  Then tell us about it.

As for sound, Canon used to put rotating gyros in IS to detect motions.  Now, inexpensive piezoelectric sensors with no moving parts are used.  They are also used in smartphones.  I think Canon's newer lens are silence also.
