Second, the motion sensors wouldn't have to work when IBIS is turned off. Yet, the noise is of equal strength regardless of whether IBIS is on or off.

On my OM-D there is a quite noticable difference in the sound level between the IS being turned on and turned off. I have no idea why you are hearing otherwise.

How do you know that it is gyros you are hearing in that case? I would rather think it is the mechanism moving the IS lens group.

The gyro sound with Canon lenses is there even if the lens/camera is held stable. The gyro spinning sound continues several seconds after the shutter is let go, when no lens correction movement would be taking place.

Note that the causes of the E-M5 IBIS noise were discussed in considerable detail on this forum about the time the E-M5 was released. Some people advanced your hypothesis already at that point but it was quickly shot down for the reasons spelled out above.

I had googled older posts. One of the big theories originally was fan noise. I don't see where the gyro theory was disproved. If it sounds like a gyro and acts like a gyro, I would suspect it's a gyro. Maybe someone will take the camera apart and prove otherwise.
