A Tennessee woman, Ali Perkins, made an unusual discovery when she opened her dishwasher and heard faint voices coming out of it. She initially thought the sound was from a radio station, but quickly found it to be true. She shared a video of the phenomenon on TikTok, which quickly went viral. Some users, including engineers, offered their insights on the issue. Perkins plans to share these findings with an electrician who didn't know how to fix it. The phenomenon, known as radio frequency interference, is caused by ungrounded or loosely grounded wires or metal or a breakdown of internal shielding or filtering in a machine's components.
