Static noise from computer speakers

Whenever a mobile is near the computer and goes off, theres a really horrible static sound coming out of the computer speakers.
I just bought a cordless phone today and its near the computer (only phone outlet is near the computer) is even though the phone doesnt go off, the static noise goes off. Is there a way to fix this?

Someone more knowledgeable may speak up, but I don't think so without moving the phone in some way. We had the same problem at our house with a portable phone and our dsl wireless modem. We never were able to have them in the same area without causing trouble.

If you can't move the phone, can you move the speakers a bit?

I just more the speakers away enough so it does not make that sound.

Digital phones often result in a characteristic buzz-buzz sound when the signal is picked up by audio equipment.    If you can't move the phone further away easily, try to isolate where the interference is being picked up.

Adjust the volume control on the amplifier/speaker units.  Does it alter the volume of the interference as well?   If so, then unplug the speakers from the computer and see if the noise is still present. 

Hiya,

Couple of things

1. Get an extension cord and move the cordless base station further away from the PC

2. Sell off your current PC speakers, and look for 'Magetically Shielded' speakers

The 'mobile' static usually occurs when the phone is communicating with the Base station or 'Cell Site' its currently sitting in. Happens every so often. If/when a call comes in, you can tell with an increase in intereference and the characteristic sound it makes if the mobile is close to some speakers or audio equipment connected to speakers.

I'm not 100% sure if all the 'computer speakers' you see in places like PC world are magentically shielded - I'd assume they are as they often sit close to PC monitors. You could *cough* buy some modest speakers from PC world, try em out and if they dont get interefered with keep em else take em back *cough*

Good luck!

They're not.   That won't help if the interference is being picked up on the interconnections anyway. 

Wrapping the power and/or signal cables through a ferrite toroid a few turns can act as a filter to attenuate the interference, although you'd need to experiment a little to find the best arrangement.   Keep all the computer leads as far from the phone wiring as possible too, and especially avoid parallel runs.

Very nice tip, gonna try that. OP, look up Farradays law, or the Farraday effect. Basically wireless objects must communicate via (relatively high) EM spikes. This causes the noises you hear in your hardwired devices. The means Paul_1966 mentions is used in current TV co-axial cables as copper shielding.

How to avoid it? Move the EM transmitters away from the problem, place a TV right next to a PC monitor to see what I mean.

 

What frequency is your phone?  2.4ghz?  You could try switching to a lower or higher one if available.
