How To Cure GSM Speaker Buzz
Posted by Brian Lam at 4:30 AM on August 4, 2008
Maclife suggests ferrite beads as a fix for the GSM buzz emanating from speakers when placed near a busy mobile phone. I found some of the snap variety you can order from Radio Shack, but am unsure of this trick working when it comes to situations where the entire length of cable is receiving interference, or on an input cable like that on a tape adaptor where the signal eventually gets amplified.

I for one, welcome GSM buzz.
It allows me to predict the future.

Weirdly enough, I had a clock radio that was so fucking cheap/lousy/sensitive that even my CDMA (Verizon) phone would cause short bursts of static at random intervals (talking to the tower and calling home? Because, phones do actually do this...) to the point where it would wake me up at night. Eventually I could use it to tell when a call was coming in.
I threw that fucker away.

"toododo toododo tododo" I last heard more than five years ago.

Oh noess!!
I've actually grown accustomed to this sound. Short loud bursts = random cellphone garbage.
Sporadic loud bursts in 1 sec intervals = incoming text/call

Eh, just wrap the cord around one and give it a try, or get one of those snap-on ones that you find around modem cables and try it. I could see how it could work some.
But, that damn buzz is why I've never switched to a GSM carrier.

IDK about you guys, but that buzzing allows me a few extra precious seconds to rummage through my pile of crap and find my phone before I miss it... that is... if anyone ever calls me :(

Worked for me. If you look at the system boards of most computers you find these little beasts all over them. Usually where a port exits the computer. Been used for years to get FCC certification on electronic devices.

Don't make cracks about "abomination[s]" (sic) in RVs when you talk about "busy" (sic) cellphones in a prior post. There are people out there with sharpened carbine red pencils ready to go on the attack!
To the pediments, grammerians!

a cell phone?
i have had many carriers and this only ONLY happens with att or cingular before it and whatever the hell came before that.
it has something to do with the carrier frequency,

tried 3 different GSM phones on ATT, 1st gen iPhone, 3G iPhone and Palm Centro, nada! All with different Sim cards, not that it probably makes a difference, but this is a crock!
You're mileage may very, but seriously, doesn't work!

$1.25 each for the kind that snap on:

@leetXcore: When my boyfriend and I were talking over Skype, he used to tell me "somebody's calling you" several seconds before my phone rang because the mic cord would pick up the phone signal. It was sort of funny. I guess it depends on the length of your speaker or mic cord and a bunch of other variables.
But @Titus_Andronicus: They SAID it was a problem with GSM phones, can you not read? And it's not "ATT or Cingular", they're the same thing now.

Or you could save money and not put your phone ontop or near the speakers. Only humans would come up with a solution that requires money instead of using common sense.

My old verizon treo did that all the time. I haven't experienced it yet with my iPhone, but it's not that big of a deal unless you're in the studio. Then it picks up like crazy. Especially on the old analogue boards or on a reel to reel machine. In that case it's phones off in the studio reguardless of what kind of phone it is. It is kinds cool. When that happens so you know that a call is coming in lol.

@BratPAQ: I believe that for best effect that you should use two -- one at each end of the cable -- and that you should loop the cable around each of them once.

I found out that dropping my husband's Crackberry into an old coffee can kills the buzz in my computer speakers just fine.

Someone correct me if I'm wrong, but don't most handheld radios use the headset as an antenna? If so, is this why many of the cords will pick this up, in the off chance they're plugged into a unit that uses the minijack as an antenna input.

Yes it gets put on the side going into the speaker. If you've ever had a clock radio with one of those wire antennas you can see the principal of how the speaker wire can act the same way, so shielding it right before it goes into the device is best.

cheap and simple fix which works for my ATT phones...
place the phone on top of one of those static-bags that hard drives are packaged in. no more buzz from the speakers. Free solution to a common problem. enjoy.

There's a loudspeaker at my work that buzzes every time I get an AIM or text message, seconds before the actual message arrives.

Does anyone know if this would work on a headset for a regular phone? I often get interference where my headphone line hangs down next to my cell phone.
