This has come up often on this vehicle. The noise typically comes from the AC compressor clutch. When the AC is turned on the clutch should engage tightly and spin with the AC compressor pulley. The clutch tends to make noise once it engages due to too much clearance between the clutch and the pulley. There are some flaws in the design of this compressor and the clearance is not easily adjusted. Though this will not cause any adverse issues with the car, the best way I have found to repair it is by replacing the compressor. This is an expensive option to fix the noise when it does not necessarily need a compressor. It is still best to verify that this is indeed the noise. To do this I would enlist the help of a certified mechanic, like one from YourMechanic, that has the knowledge to identify the noise.
