This isn't a homework problem or anything, but a problem plaguing me at home.
I have a set of speakers that pop occasionally. The pop is uniform across all satellites and subwoofer of the speaker set (there are 5 satellites and 1 subwoofer). The speakers are 500 watts RMS, 1000 watts peak.
The speakers pop whenever the mini-fridge in my dorm room turns on or off. They also pop if I have the speakers at home and I turn my fan on or off, or from one mode to another.
The fan and mini-fridge are on the same circuit. In the case of the fan, it's in the same surge protector. The speakers still pop if I turn the fan on/off when it's plugged into a wall outlet on the same circuit.
Some people have told me electromagnetic interference may be causing it. To test it, I plugged the fan into another circuit in my house through an extension cord, and placed the fan where it normally rests. I turned it on, and the speakers don't pop.
The speakers don't pop at all if they're turned off.
My suspicion is that there's too much power being drawn from all the devices on the current circuit, so how can I alleviate the popping? Which would be more suitable, a backup power supply (UPS) with automatic voltage regulation or a home theater type power conditioner?
And if my speakers pop when I do something as simple as turning a fan on, why aren't my other peripherals affected? Say, the other two computers on the same circuit. Could the sag in power when I turn my fan on be harming these components?
Thanks for any insight.
