No road trip is complete without music. Be it a routine drive to work or a road trip, good music via the AUX system will always be essential. Unfortunately, you immediately start hearing unpleasant static or buzzing sounds once you start charging your phone.
You will for sure get annoyed enough to pull over and see what’s the matter with your car’s stereo. What’s even more annoying is realizing that the root cause of this irritating sound is charging your smartphone using the car’s built-in cigar charging port. Well, no matter how much you twist and turn the AUX cable, it won’t fix this issue until you disconnect your phone from the charger.
But that is not the solution because without charging your phone’s battery, the time you can keep listening to your songs is limited. So how can you escape this predicament? Well, we’ve got your back. In this guide, we have listed three ways you can stop the static noises from the AUX while charging your phone via the car’s cigarette lighter.
But why is this happening? The most common reason for hearing a weird static disturbance on the car’s stereo is the ground loop problem. Let’s dig a little deeper into what it means and how can we fix it.
The Ground Loop Effect
A ground loop could be the most likely reason if you suddenly hear an annoying noise springing from your car stereo. This may not be present in all cars, but it is very common to get this issue, especially when using an AUX cable to stream your music.
A ground loop occurs when the two components of your car stereo get anchored in places with different ground potentials. Whenever this happens, it causes a potential difference, resulting in the interference in your songs that you hear as a humming, buzzing, or hissing noise.
However, hearing an interference on your car’s stereo doesn’t always boil down to the ground loop problem. Yet this problem is definitely one of the most common culprits when it comes to creating unwanted issues with your car’s stereo system.
So to solve the ground loop issue, you need to balance the potential difference by establishing a proper ground connection. Sounds too technical for you? We don’t blame you. Don’t worry because we have also listed two easy ways to fix this issue.
How to Fix the Ground Loop Noise Effect in Your Car?
Solving a ground loop problem isn’t rocket science, and you can pull it off on your own. Here are three different approaches that you can try.
Use a Ground Loop Noise Isolator
As we mentioned above, this problem occurs when there is a potential difference between the phone and your car’s stereo. So what if you could suppress this potential difference?
Yes, this is possible by using a Ground Loop Noise Isolator. It is a tiny device that acts as a bridge between the phone and the stereo. You can think of an auxiliary cable extension with a very small transformer in between. All you have to is one end of this cable to your phone’s audio jack and the other one to your car’s stereo.
Your phone sends the audio to the transformer in the form of electric waves, and the transformer converts it into magnetic waves. These magnetic waves are then converted back to electric waves, but this time the excess electricity is neutralized. So now you can charge your smartphone connect it to the stereo at the same time.
Lucky for you, you don’t have to hunt down the best Ground Loop Noise Isolator available in the market because we’ve already done that for you. It’s the BESIGN Ground Loop Noise Isolator.
