Blow dryer causes audible buzz from power amps in two audio systems...


but only at one speed.  My wife's hair blow dryer causes the amps in both my bedroom system and family room system to audibly buzz.  It only causes the buzz when the blow dryer is on its low fan speed.  Strange.  The bedroom system is close to the master bathroom, where she uses the blow dryer.  But the family room is on the other end of the house and I assume on a completely different circuit.  Now, it does not cause any problem with the audio that the amps are producing.  It is just an audible buzz you can hear coming from the amp. Does this mean there is something wrong with the wiring in my house?  The house was built in 1987.

Millercarbon, and several others, please don’t spread misinformation about how residential electrical systems are wired and how they work. Get a real licensed electrician who is qualified if you don’t understand this stuff. If you still want to do your own work, at least get educated on the subject, and make sure you have your electrical safety authority inspect and approve all work you do.

Sorry if this sounds harsh, but if you don’t understand the difference between neutral and ground, and the difference between grounding and bonding, and where to ground and where to bond, you are putting yourself and your families in danger if you undertake your own electrical work. For the record, residential electrical feed is single split phase.
