Why does my iPad Air 2 make a "popping" sound?

Apple customers are complaining on the Apple forums and Reddit about their iPad Air 2 models making a "popping" sound. It is unknown if this is a hardware or software problem, but some customers are reporting that they have exchanged their iPad and that the problem did not occur on the new device.

You should return your iPad Air 2 model to your local Apple retail location if you are experiencing this problem.
