Regain your Sanity with a $3.00 Part from Radio Shack.
I read an article the other day about stopping the annoying buzz that my computer speakers make when my cell phone is on my desk. It turns out that the noise is caused by ElectroMagnetic Interference.
If you have a GSM cell phone (just about everyone in the world besides Verizon and Sprint) the phone tries to use the wires in your speakers as an antenna. Well, actually, the signal jumps to the speaker wire and causes that mind-warping buzzing noise.
