Why does my cell phone make the speakers on my computer pulse with a static-like noise occasionally?

Answer 1

RF (radio frequency) interference. Also, if you have a call coming in, you'll get RF interference BEFORE your cell phone rings. How weird is that!

Answer 2

The area which is covered by the 'phone service service is broken up into smaller areas called cells. That's why they're called cell 'phones.

Each cell has its own base station and antenna and the 'phones in that cell communicate with it.

A cell 'phone automatically transmits its identification at regular intervals so that the system knows in which cell it is located so that incoming calls are routed to the correct cell's transmitter.

Those regular identifying transmissions are picked up in audio and other electronic equipment and that's why you hear the noise. I hear them in my PC's 'speakers for instance.

Answer 3

Your cell phone is making periodic transmissions with its network--checking in to the network base station to see if there are any incoming messages or calls for your phone. The transmission is an electromagnetic pulse, so your speakers pick up on it.

Answer 4

It's called 'electrostatic interference'

It has to do with the carrier wave of the cell phone signal..

I never noticed it with any previous service I had but nextel, but I get similar results from my current t mobile phone.. Nextel is by far the most obnoxious noise though.

It's harmless, albeit annoying.

Answer 5

When I contacted TracFone about the same issue as yours, this was their reply:

"As regards your concern, the sound you hear is normal on GSM phones, since they are exposed to radio waves.

This model wireless phone meets the government’s requirements for exposure to radio waves. Your wireless phone is a radio transmitter and receiver. It is designed and manufactured not to exceed limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S. Government and by the Canadian regulatory authorities.

In general, the closer you are to a wireless base station, the lower the power output.

In the United States and Canada, the SAR (Specific Absorption
Rates) limit for mobile phones used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a substantial margin of safety to give additional protection for the public and to account for any variations in measurements."

(Yeah, I didn't understand it either.)

Answer 6

because the sound receiver is very close to the speaker. thats why you get a static-like noise

Answer 7

because cell phones emit a signal that the monitor senses

Answer 8

Electrical interference

Answer 9

if your speakers are wireless it is because your cell phon signal is interfering, otherwise i dont know

Answer 10

if u have nextel i think they all do it my bf does 2
