Acer monitor siren

So what does it does this every now and then? It'll go months between doing it. It comes from the monitor not the speakers and turning off the monitor stops it. Weird.

Why would a monitor be able to make a noise? Does it have speakers in it?

It must have yes. There plenty of other videos on youtube and posts about it. No one seems to have any idea what it is or why it does it.
