Electromagnetic fields (EMFs) occur naturally in the world in the form of solar energy but also come from a variety of human-made sources including power lines, cellphones, microwaves, WIFI routers, and radios. EMFs are invisible waves of energy radiation, and some studies have found possible connections between low-level EMF exposure and health issues. As a result, some individuals are concerned about EMF exposure and seek to reduce their risk in everyday life, and this includes limiting vulnerability to EMFs in automobiles in the form of car audio and stereos. Many cars have Bluetooth devices and satellite radios installed that can offer drivers the convenience of listening to any type of music, as well as Podcasts and other audio programs. Research shows that the low-frequency magnetic fields produced by radio waves (Rfs) create circulating currents within the human body. Although short-term exposure to high levels has been shown to negatively affect health, scientists state that exposure to low levels of radio waves should not be a concern. However, public uneasiness over EMF exposure has led to questions regarding the effects of EMFs emitted by car audio systems.
What Kinds of EMFs Do Car Audios Emit?
These days most cars emit some level of EMFs from electronic parts and devices, including wireless and cellular technologies. Keyless door locks, GPS devices, multimedia entertainment systems, WIFI, Bluetooth, and cell modems are examples. Depending on the car, audio and multimedia speaker systems typically emit ELFs (extremely low frequencies) when Bluetooth or WIFI systems are enabled. ELFs are a type of low-energy radiation that travels in long waves, and the most common sources are electrical wiring, power lines, microwaves, and hair dryers. An audio system or a car radio converts radio waves to mechanical vibrations, in-car speakers, creating sound waves. One of the main concerns about EMF car audio exposure is the radiation waves emitted from WIFI, satellite radio, and Bluetooth technologies. However, there are certain things you can do to limit your exposure to EMFs while using your car audio.
How Can I Limit My Exposure to Car Audio EMFs?
If you are concerned about exposure to your auto’s multimedia and audio systems, there are several things you can do to limit your exposure, and some include the following:
Use a USB port for your car audio.
Most modern cars have built-in USB ports to charge cell phones and other devices. If you have an older model car or one that does not have a built-in USB, you can always purchase a USB device that can be plugged into the cigarette lighter. Instead of using your satellite radio or Bluetooth to listen to music or audio programs, plug in your cellphone to the USB port and listen to your favorite music. Most cellphones and other devices store music in the form of mp3 files, and the amount of mp3 files you can store on your cellphone depends on your phone and how old it is. Most smartphones can hold up to 16GB of music, which is equal to about 4,000 songs. The nice thing about using the USB port is that you limit the EMFs emitted by your WIFI, satellite radio, or Bluetooth devices, and you can charge your cell phone while playing music at the same time. You can also operate it all with the controls of your vehicle stereo system rather than your cell phone.
Use an auxiliary cable
To play music on your cellphone or another device, you will also need an auxiliary cable in addition to a USB connector. If your car has a built-in USB, this will be fairly easy. Most modern cars come with an auxiliary port that is connected to the sound system, and you simply connect the cable to your phone, insert one end into your car stereo system, and play your favorite music through your car stereo speakers. The only drawback to this idea is you have to control everything from your cellular phone, and not your auto stereo system.
Turn off all wireless, cellular, and satellite audio functions
If you are happy listening to audio and music through your phone via a USB device or an auxiliary cable, you don’t need to turn on the WIFI connected to your car’s multimedia system. By turning off the wireless, cellular, and satellite systems, you limit your exposure to EMFs emitted from these devices.
Use an EMF meter to monitor EMF levels in your car
If you suffer from EHS (electromagnetic hypersensitivity), or would simply like to limit your exposure, consider using an EMF meter to monitor EMF levels in your car. These meters can be purchased online, and measure existing electric and magnetic fields in an area.
Try EMF protection clothing and jewelry
EMF protection clothing and jewelry can also offer added protection while listening to music in your car. These items can offer protection for both older car radios and newer models. Most clothing can help to limit exposure to electric fields and radio frequencies, and jewelry consists of different types of fashionable crystals and elements that can help to absorb and perhaps even repel EMF radiation waves.
Turn off the radio
This may be self-explanatory, but if you don’t mind a little quiet while you drive, turning off the radio along with other media systems can help.
How Can I Test EMF Emissions From My Car Audio System?
If you are concerned about EMF radiation waves from your car audio system, or if you suffer from a sensitivity to electromagnetic fields, testing EMF levels can help you discover the extent of electromagnetic radiation emitted from your car audio system. Many EMF meters run $100-$200 and come in a variety of types and styles. They function to measure AC (alternating current) and DC (direct current) electromagnetic fields, as well as ELFs and RFs. When testing EMF emissions from your car audio, you can test in the following locations:
- The audio and media unit. These consoles are usually located in front of the center consoles of most vehicles and may include a DVD player, video screen as well as a radio.
- The diver and passenger seats.
- Near the gear shift.
- Below the steering wheel.
- Locations where your head, torso, and legs are while you are driving or riding as a passenger.
As public concern grows regarding the effects of EMF exposure from devices such as car audio systems and radios, the good news is that there are steps you can take as a driver to limit your vulnerability to these invisible energy waves. These steps include disabling WIFI and Bluetooth systems, using USB ports and auxiliary cables, or just simply turning off your car radio. EMF protection clothing and jewelry are also options, and these items can provide you with protection no matter where you are.
