This area is too small for 60 Hz, but there’s a lot of microwave crap that would get picked up. If there isn’t a low-pass analog filter before the next silicon junction then this RF EMI will get rectified down. If it’s a sufficiently bad situation then you’ll hear it. That’s why you can hear garbage when you put your phone right next to crappy computer speakers.
