I have recorded the noise with my phone and posted it to youtube. The sound is clearly audible at the end of the video, when the IS shuts down.

Mine sounds similar to yours, but yours may be a little bit louder.  It was hard for me to determine the proper volume on my computer to hear it as it should be.  However, mine reacts the same as yours, but the sounds may be a little different.  Mine sounds more like a muffled screeching noise which I presume is normal.  I haven't had any difficulty with it at all.
