It is a noise coming through the speakers themselves. As many have pointed out, it is almost definitely feedback of some form.
Like back in the day when leaving a 2G GSM phone next to some computer speakers, it would make certain buzzes as it was receiving a text message or phone call.
This happened to me at work, a coworker planted a listening device in a wooden mallard and gave it to me as a gift. He was trying to collect evidence against me for attempted blackmail. I put my phone next to it and heard the staticky feedback which gave it away.
What tha heck? You can't just leave us hanging, How'd that play out?
Haha I was just kidding, that was a plotline on The Office.
Why would a listening device have speakers though?
Because he used a walkie talkie in the wooden mallard as a listening device and it was actually from an episode of The Office
But did you check your pens?
Haha no? What kind of a psychopath would use a secondary listening device?
