If you have a cell phone near any sort of electrical equipment that emits noise, old or new, you'll hear that skipping buzz noise. What causes this exactly, what is it, etc?
The cell phone in fundamentally a radio. Radios emit radio frequencies energy which will interfere (RFI) with other audio equipment like an AM radio. You hear the noise while the phone is communication with the tower. It does this from time to time to let the tower know it is online and ready to receive data and of course to transmit/receive data. Hope that helps.
