Clicking - popping noises

I have an issue with hearing popping sounds when using my iPhone cell phone. However, I can now easily reproduce this. Holding the cell phone against my right ear and talking for at least 10 minutes causes a popping/clicking noise that appears to be coming from inside my head and perceived in my left ear. At this time, my iPhone is very warm -almost hot. To make sure that the sound is not sourcing from the iPhone speaker, I hold the phone at arms length. It is still close enough to hear the conversation. However there is no popping/clicking sound. Placing the iPhone against my right ear again cause the noise to be perceived again. I cannot reproduce this by holding the phone against my left ear. This is all very disturbing, especially since I can reproduce this every time. At first I dismissed this as a form of tinnitus or some other sinus related issue. However, after talking to several people who have "heard" this as well, I am now confident that there is a connection between an overheated cell phone being held against the skull and sound being perceived in the opposite ear. If anyone can reproduce this, I would be interested to hear this. -Bill
