why do my computer speakers pick up a signal just before my cell phone rings and even when it does n

I have heard that brief buzzing when my older cells were near my clock radio; my newer digital phone doesn't seem to cause it on the clock radio or near my computer.

I often hear the interference from cell phones through my more sensitive audiometric equipment at work, and I have to ask my patients to turn them off -- they never seem to read the signs I have posted!

Even if you are not transmitting or receiving a call or text message or other data, the phone is actively connecting with the cell service so it may cause the buzz at any time when its power is on.

I don't know the specific electrical/radio frequency cause of the sound, however. And I only just realized that my newer phone doesn't do it in the process of answering this question. I do know that cell phones can also cause problems with hearing aids, and there is a certain technology in the phone to look for to reduce/eliminate the problem, and it may have something to do with this issue, as well -- I'll see if I can find out more… I believe they are too fast Ha, don't know, mine does too, though. I can tell when my friend has just called and the phone is about to ring. it means that there is a wave interference between your PC speakers and the phone. it is so because they all use electrical/ radio waves. but it's no problem. Your phone transmits sideband noise when searching for, sending, and receiving a signal. Speakers "hear" this interference and respond the way speakers were created to. Move it further away, including wiring, and you won't hear it.
