Some user had the same issue awhile back, only not so loud. My guess, some sort of protection tape came loose (yes, Acer uses a lot of tape on the inside). Either that, or a grounding point is loose on the inside.
If it's under warranty, send it back.
If not, pop the back off and poke around a little. There's some guides somewhere in the general or q&a forum. Also some you tube vids if you search.
Also, dirty electrical in the house/apartment can cause this as well. If you have a really good power strip with noise filters, you can try this also. Or go to a new facility and plug it in there and see if it's the same.
