It's been a while since I did anything other than 'lurk' on the site... but some interesting things have been happening to me lately, and I wanted
to share, and get some opinions.
For the last three days, I've been hearing noises on my speakers. It is the sort of noise you get when an active mobile/cell phone is placed near a
speaker, or music system, and causing electromagnetic interference when it's active. You can get an idea of what I mean
On my speakers though, the interference is a lot quieter. As though whatever is causing the interference isn't right next to the speaker system. It
is certainly close enough to cause the problem though.
The speaker system is an old-ish Creative 5.1 surround sound system. It's connected to my computer, and near a wi-fi router. My computer is never
I have turned off the router completely, to see if that had an effect. I've got the sounds on the speakers even when I leave my mobile phone in
another room, or when I have totally turned it off and disconnected the battery (it's a very old phone - but it works and I like it). I have tried
moving the speakers and sub, but to no avail. I've disconnected them from the computer, and still get the sound. I even shut down the computer and
disconnected it from the power supply. Still I get the sound.
I don't use many other electronic devices, and certainly not ones that have the ability to transmit and cause EM interference in speakers such as
The only time the noise of interference can be stopped is when the speakers are turned off pysically.
Turning them up or down doesn't make a difference in the volume of the interference.
It's also worth noting that the EM interference noise isn't constant. It comes and goes with no discernable pattern. Sometimes it lasts a few
minutes, others it lasts an hour or more. The gaps bettween the interfence happening are similiarly irregular.
I've searched the room for any mobile phones that might have been left behind by visitors to my home, and found nothing.
There aren't any base stations that are very close to my hosue. The nearest is quite a distance from my house and there isn't a clear line of sight
to the speakers from the mast.
Does anyone have any suggestions as to what could be causing it?
One of my friends suggested I'm being monitored, and it's a bugging device that's transmitting all conversation from my house back to the NSA or
GCHQ or something... which amuses me, since I'm wouldn't consider myself someone who's worth monitoring... but who knows!
Any ideas or suggestions would be gratefully appreciated though.
