That's the noise of the piezoelectric cleaning system. It vibrates the low pass filter (located just in front of the sensor) to shake dust loose.
In some cameras it sounds like a couple of squeaks. My 60Da makes the same noise. No reason for concern. Some cameras start out not squeaking when new and end up making the squeak later.
The good news is I have never heard of it actually being a problem.
No, the good news is that the OP is still young enough to be able to hear a squealing sound at such a high frequency!
