Try turning it off.
Try resetting it, hold down the sleep and home keys, past when you see the red power down slider and until you see the silver apple. Let it reboot and see if that helps.
I've also gotten that chirping to go away by simply unplugging and replugging the charger.

It's happening because the iPad is not getting constant power into it.
Make sure all connectors, plugs are securely plugged in(iPad and wall socket).
