Anyone know if it's possible to stop this? It never really used to be a problem, but where I'm now in a smaller room it seems that no matter where I have my phone, it interferes with my speakers.

On the plus side it makes me look psychic because I can grab my phone before it actually starts ringing, and hold it for a second or two before the call/text arrives.

------------

To answer my own question: I assume that it's either the speaker wire or something in the speakers/amplifier that is acting as an antenna. So presumably shielding the wires or something inside the amplifier is the solution. Presumably I have the problem because my speakers are cheap.

Perhaps tin foil inside the amplifier, wrap it up, or something ... and I guess it would make sense to Earth the foil.

Also, it doesn't happen with all phones. So it must only happen with phones that use X to transmit data, rather than Y.

I suppose I should try and identify if it's the satellite speakers, the wires, or the sub-woofer causing the bleepingness.

It's the most annoying sound of our generation.

I have the exact same problem at work, trying to listen to Spotify, immerse myself in paperwork and then the bosses (office next door) phone rings, radiating interference right to my low-class Labtec speakers which start going as liq has explained above.

I've bordered the issue to be the left speaker, I.e. the one with the power input. If I cover the speaker with my hand between where the signal is coming from, it dampens. I get a similar effect when rotating the speaker a bit.

Usually I just turn the speakers off and silently swear to myself.

I need around tree fiddy.

buy some "snap choke cores"

they are iron ferrite rings that cancel out electro magnetic interference.
clip them onto the wires of your speaker and push them up as close to the speaker as you can get

i think local radioshack or similar store should stock them

That sounds interesting.

Yeah, I think it would be unshielded wires picking up interference. I've got logitech z-4's in my room, and every time I got a call or sms on my old phone, I would get the interference noise a second before. It was quite handy actually, cause that phone failed to actually ring sometimes..

I've also got a weird problem where I'll hear static when someone rings the doorbell (I'm in the room above the entrance to the house). However I also hear it when listening to music via my HD555's.. , so I'm not sure whats causing that one..

I don't get any interference on any speakers at home.. Hmm.. I sometimes pick up weird AM radio stations on my guitar amps but that's it. It's just at work where it busts my nuts.

I do get monitor flickering when my amp is on (same outlet), and sometimes a massive SNAP from my Creative 2.1:s when I turn off the bathroom light. Go late 50's wiring!

I'm going to be very happy if the RF-interference issue liq posted will be solved here.

You want to make that? I was keen on doing that too, but then I scrolled down to the part that a ferrite sleeve is needed and thought "f it".

Sounds like far too much effort tbh. Especially seeing as I have surround sound (i.e. lots of cables).

There's nothing you can do. It is usually the amplifier, speaker wire or actual speaker coils that pick up the cell phone interference. Aside from moving into a Faraday cage, that is.

The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP

So why do my cheapy 2.1 speakers on my TV make the noise and my Gigaworks surround system doesn't? Must have some sort of shielding going on there.

They probably have the amplifier shielded. All amplifiers should be shielded, but those cheapo manufacturers usually just fuck it.

Any way to shield the amp in the cheapies? I've given them to a mate now but he's getting just as annoyed by it as I was lol.

They didn't fix the problem. It's only phones using GPRS signal that do it. If you have a 3G signal in your house, you will get no interference. My old Nokia 6300 did it all the time, then I bought a new Sony Ericsson C510 and I get no more interference.

Solution? Buy a new phone.

Get some double sided tape and put it on the ceiling in the middle of your room. Hopefully your phone will be far enough away to not interfere if you keep it there.

If you need ferrite rings i think i have some, somewhere, in the wilderness that is the 'underneath my workbench'.

Minor development: If I cup my phone in my hands when it's ringing I can substantially reduce the loudness of the speaker bleeping.
