Speakers pop when turning off fans in house...

[chuckears]

Wow, talk about a blast from the past!

...I have not had a problem with this since I installed two Richard Gray Power Company boxes between my gear and the newer dedicated line. They were pricey (even though I bought them used), but all of my equipment has survived some pretty wicked storms and power surges, including the whole-house power loss from a weather-head pinch that fried my computer during an ice storm a few years ago (tree limbs fell on the weather head).

...and nary a "pop" through the speakers for years now.

I had the same issue after a light switch was changed recently. ONLY ONE switch and it was easy to find due to the replacement.

I pulled the switch, replaced with a quality switch, and NO more pop through the speakers.

Hi,

 

So I'm experiencing this, however, the speaker is from a toy, with its own battery system. I'm thinking maybe it's the electromagnets of the fan messing with the ones in the toys speaker? It can't be electrical, as they are both insulated in dependant circuits... Also strange that it only beeps in certain positions on the ground

Isolation Filter on the power fixes that.  Hard to get one $$ to handle heavy load though.  Dedicated line would likely be best but still talking $$.  Isolation filter fixes more ills though.

It's obviously electrical in nature.  The question is "how?"  If not getting through common supply wiring then it has to be airborne.  (Which the other device's relative location / orientation would affect (see Dean?) "reception of.")  Either way I believe a suitable capacitor across the fan switch contacts would snub the release of the switch-opening electrical noise.  No, I don't have a value in mind.  I'm confident google (or my now-preferred Duck duck go search engine) will provide some ideas.

 

I'm unaware of how the "common" (white) wires could possibly be not bonded to earth as mentioned above years ago.  The last code I've seen was current in 2007.
