My guess would be that it's a phenomenon called "coil whine". Read more at: http://en.wikipedia.org/wiki/Coil_noise
But it's basically the LSM units themselves that vibrates due to the magnetic load they are experiences as the train goes by.
It's very similar to many electronic things today (computers, screens, chargers, etc) which can emit a high pitch noise when in use.
Official Helix POV!!
Embedded the video from above:
A couple of things that are noteworthy on that POV.
The perspective makes will make the ride look very different in reality, the camera is mounted at the level where you have your feet.
And it's running slow in that video, I reckon that it will have to speed up about 10 seconds on the coasting bit to live up to the calculations done for Helix.
So it will get even better
