[–] algorithmae@lemmy.sdf.org 8 points 2 years ago (2 children) Yeah, the same way a radio tuned to a station could be static until you plug in an antenna. You could also get hums and interference from other sufficiently strong EMF sources, like how AM radios can pick up the sound of transmission lines permalink fedilink source parent hideshow 4 child comments replies: [–] dohpaz42@lemmy.world 8 points 2 years ago Your mom (or dad) using an electric knife to cut a turkey on thanksgiving would do the same.
