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
Your mom (or dad) using an electric knife to cut a turkey on thanksgiving would do the same. It was wild.
AM car radio can pick up the waves from your cars electrical alternator as well, which can cause the static to rise and fall in pitch as you speed up and slow down.
