How to Get Rid of Hissing/Buzzing Sound Caused By Ground Loop in Your Car Stereo?

Have you ever experienced hearing an annoying whine, pesky hissing or buzzing when you plug your mp3 player, iPod, cellphone, SiriusXM satellite radio or any other multimedia player into the AUX input on your car stereo system? It could be caused by ground loop.

Ground Loop: Defined

Ground Loop is defined by Digital Media Dictionaries as “hum caused by currents circulating through the ground side of a piece of equipment or system, due to grounding it at points of different voltage potential.” This is different from the term ground-loop used in aeronautics which is referred to as "a sharp horizontal loop performed, usually involuntarily, while touching the ground” (as define by Dictionary.com).

Ground Loop Isolator

Car power outlets do not have an in-line noise reducer so the noise is being caused by ground loop from the power outlet. A Ground Loop Isolator (Model: SNI-1/3.5 or 3.5 Noise Filter) may be plugged into the AUX IN in your car. It is a simple device thus, you can install it yourself. This device eliminates the ground loop noise between an auxiliary source and any AUX capable portable player or radio. The device includes a female 3.5mm input, a male 3.5mm output, and cable which is normally 10 inches long. The price ranges from $9.00 to $15.00.

So you know now what to use when you hear that annoying hum. Music is created to sound pleasant to the ear. It makes no sense listening when there is interference.

One of my degrees is in applied electrical Engineering, so I was really curious as to see how you was going to proceed with this article. You handled it differently than I would have, but you handled it beautifully.

Very well done, Cowboy. Love the hat. I'm a Stetson man myself.

As regards the "ground loop", this is on my "can't do" job list.
As regards the 23 hats, no comment.
Thank you for an informative and entertaining page.
