Headphones bad to use as radio receiver?
pr3ciouzboi - 6-24-2012 at 11:52 AM

Does anyone here know whether using headphones to receive radio signal for devices such as cell phone would be bad or not?

My cellphone requires me to use a headphone to receive signal for the radio option. As mentioned above my concern is, would the radio signals that are being transmitted to the headphones be harmful to your brain?

I am aware that having your cellphone/laptop anywhere near your body can already have negative impacts to your health.

If anyone would have a plausible explanation, possibly with a credible source for backup, that would be great. Thanks

radio waves are constantly bombarding you; whether there is a headphone or anything else to receive them, or not

Correct but not precisely. you must consider the distance from the source and the amount of waves you are receiving

??
he's talking about receiving not transmitting

Whether you are naked or have a satellite dish mounted to your forehead, it shouldnt make a difference. It doesnt increase the radio waves that are being shot at you

Depending on how your head/body acts as a receiving antenna and how you are positioned to the transmitted signals, the antenna wave pattern can hit you at different ways. The "surface area" of the antenna pattern that hits you is the amount of radio waves you are in contact with. Whether or not radio waves are harmful is a different story.

have no fear bro, i've got your back

you need to wear an AFDB, here's the instructions for making one.

short answer: no

not-so-short answer: radio waves are bombarding you anyway and using the headphones to receive the radio waves, you are just putting them to good use. think of radio waves as sunlight which is around you anyway, and by opening your eyes (putting on the headphones) you seeing light. Closing your eyes doesn't make the sun light go away.

long answer: radio waves are a type of electromagnetic waves (so are infra-red, visible light, ultra-violet, microwaves, etc). Electromagnetic waves are all around us and bombard us constantly. What makes some electromagnetic waves 'harmful' is that the energy in that specific type of wave is so high that it excites/knocks the electrons off of atoms (also known as ionizing)(examples include prolonged exposure to ultraviolet waves... which is why you put on sunblock)... think of holding a long string and you swing it so much that a part of the string breaks off. Now because these atoms (your skin or other organs) lose electrons, it starts reacting with nearby atoms... which is what your DNA is made up of and since your DNA determine how your cells replicate, if they get messed up by these ionizing electromagnetic waves they replicate incorrectly (or out of control) causing cancer (which is uncontrolled cell replication). NOW... how do you determine if a certain electromagenetic wave has high energy levels... well that depends on the distance of the SOURCE (in this case the radio transmission TOWER) and the electromagnetic wave (the radio wave). In general, radio waves are long wavelengths low energy and should not be ionizing. However, if you are dry humping the radio tower, your body may feel warm and fuzzy on the inside because it is exciting your atoms (perhaps not to the point of ionization, but it makes them hot). Since I hope you aren't THAT close to the radio tower, simply putting on headphones to listen to radio waves will not do you significantly greater, if any at all, harm.

Using any type of electronic device causes harm but that doesn't stop us from using them regardless. The headphones act as an antennae so the way I see it, there is no different from listening to the radio in your car or wherever else.

Thanks for all the detailed answers. I do am aware that magnetic waves are surrounding us. I am just concerned by using headphones, the signal that is being received will be amplified causing greater damage than if you are not using any. True?

Of course people might simply say: "then don't use listen to the radio", which isn't the obvious answer I am seeking for.

Any thoughts?

It could only be dangerous if you are standing ON a radio tower, which can be hundred of meters tall (or more) so there is no way it can be harmful.
The signal is capted by your headphone that serves as antenna and it is amplified afterwards as an electronic signal (and decoded) so, as soon as it is capted by your headphone it's technically not an radio wave anymore. (there is no amplification of the radio wave on your side).
Also, since the signal is absorbed by the antenna, you can deduct that your body must probably absorb less of it. But the human body isnt a really good antenna anyways.
