Wow, that is pretty bad wiring. I can hear an audible hum from my subwoofer when my wife runs the vacuum or blow dryer but that’s about it. And those are about the highest pulling appliances you could have in a household and the sub is pretty big with pretty powerful amp.

Brushed AC motors degrade power quality, although they're normally equipped with filters.

Right, similarly to my dimmers that constant gating of power draw as the brushes make and break contact just wreck your AC circuit.

Bad wiring and a sub-par setup will make that bleed right through your speakers.
