The FCC and whoever else approves those levels of radiation to be within permissible limits, but the International Agency for Research on Cancer classifies the relevant Electromagnetic Field (EMF) radiation as possibly carcinogenic (http://www.iarc.fr/en/media-centre/pr/2011/pdfs/pr208_E.pdf). The FCC has also decided to review its assessment scale (http://www.nytimes.com/2013/03/30/business/fcc-to-study-health-effects-of-cellphone-radiation.html?_r=0) to decide whether the ratings should be changed. The current standard is < 1.6 Watts per kilogram (averaged over one gram of tissue) (http://transition.fcc.gov/oet/rfsafety/rf-faqs.html#Q12).
The FCC has also addressed the specific question of "DO "HANDS-FREE" EAR PIECES FOR MOBILE PHONES REDUCE EXPOSURE TO RF EMISSIONS? WHAT ABOUT MOBILE PHONE ACCESSORIES THAT CLAIM TO SHIELD THE HEAD FROM RF RADIATION? (http://transition.fcc.gov/oet/rfsafety/rf-faqs.html#Q13) On that point: Quote from: FCC Office of Engineering and Technology "Hands-free" kits with ear pieces can be used with cell phones for convenience and comfort. In addition, because the phone, which is the source of the RF emissions, will not be placed against the head, absorption of RF energy in the head will be reduced. Therefore, it is true that use of an ear piece connected to a mobile phone will significantly reduce the rate of energy absorption (or "SAR") in the user's head. On the other hand, if the phone is mounted against the waist or other part of the body during use, then that part of the body will absorb RF energy. Even so, mobile phones marketed in the U.S. are required to meet safety limit requirements regardless of whether they are used against the head or against the body. So either configuration should result in compliance with the safety limit. Note that hands-free devices using “Bluetooth” technology also include a wireless transmitter; however, the Bluetooth transmitter operates at a much lower power than the cell phone. A number of devices have been marketed that claim to "shield" or otherwise reduce RF absorption in the body of the user. Some of these devices incorporate shielded phone cases, while others involve nothing more than a metallic accessory attached to the phone. Studies have shown that these devices generally do not work as advertised. In fact, they may actually increase RF absorption in the head due to their potential to interfere with proper operation of the phone, thus forcing it to increase power to compensate. Anyway - I'm going to come out as stating this as a simple fact: These headphones are not capable of blocking radiation. They are however capable of preventing exposure to radiation to your brain at close range from the use of cellphone directly, pressed against your head. If you want to use a headset for that purpose, then these headphones will block your exposure to that radiation at a rate that is precisely equal to any other wired headset. Maybe marginally more if they are EMF shielded at a greater-than-average rate - but it is up to you to decide whether you are concerned about cellphone radiation in the first place, and whether any tech used in this particular headset "shields" any more radiation than any other set of headphones. Title: Re: Radiation Free Air-Tube Headphones Post by: tabbek on May 24, 2013, 11:50:22 PM It's the same type of tech that they use in headphones they put on you to communicate with you in say, an MRI or CT scan, where having a magnet, or anything else metallic wouldnt work. The sound is delivered to the ear by way of tube conducting the soundwaves from a speaker located away from the ear.
"shielding" would be an overstatement. Moving an electrified coil away from your head... that it does. Not an endorsement from me, but it's not a load of crap either.

You really can't resist it can you Grue? Do you think anyone cares about your opinion on the hundreds of market places threads you do this to? As far is the item concerned I am willing to bet that English is not the first language of the seller (if I am incorrect I apologize), and his "false advertising" is actually a completely understandable grammatical issue even for a native speaker. What this doesn't do: Block all radiation What this does do: Limit the amount of radiation traveling along the metal wire directly into your ear by creating an air gap which will create more resistance. Anything plugged directly into your cellphone can act as an antennae and can direct the cell phone's network signal radiation more directly into your skull. Air-tube headphones are considered one of the best methods of reducing this type of cell phone EM radiation exposure to the skull after using a bluetooth (which itself emits radiation but on a much weaker level). A wired headset tho is still safer than holding your phone directly to your head while in use. I don't think the OP intended any deceit yet simply made a mistake in communication. Anyone who wishes to reduce cell phone radiation to ones head, this product will do that.

More or less exactly what I was saying. I didn't realize that this was using an air tube rather than conductive media - obviously, that would reduce any radiation even in comparison with a standard wired headset. What I was getting at was a) Moving the phone away from your head reduces radiation getting to your head. If it's touching your body, it doesn't reduce radiation getting to your body, just your head. b) Any wired headphone reduces the radiation. There's some argument about how much cellular signal gets channeled through a normal wired headset up to your ears anyway, but it is less than holding the phone to your head. There's nothing wrong with using these, just as long as you understand what exactly they propose to do and how they do it. I didn't fully understand, but now I get it. They *ARE* offering an additional advantage over a standard el cheapo wired headset. Title: Re: Radiation Free Air-Tube Headphones Post by: cp1 on May 25, 2013, 04:18:51 PM There's more radiation exposure from the ground than you could ever get from a cell phone. And then we burn coal and get it in the air. It's also in all produce, and from the sun. Cell phones are as dangerous as microwaves.

Say the headset might pick up 1/100 of the EM radiated by the phone (-20 dB) and then re-radiate 1/100 of it as EM again (-20 dB). The result is that, overall, just 1/10,000 (-40 dB) of the original EM is re-radiated near your head. Combine that with the fact that typical modern phone's RF power is less than 1 W - in that case, a mere 100 uW (micro watts, or millionths of watt) would be re-radiated near your head.

Tell me, why is it that a piece of metal can seemingly absorb energy at will and redirect it to a specific place? Antennas either absorb or emit radiation. Whenever it's emitting radiation, the radiation radiates in all directions (https://en.wikipedia.org/wiki/File:Felder_um_Dipol.jpg) (unless the antenna is directed like with satellite dishes). The metal is not just near your head, it is directly connected to a transmitter. I don't know if you are aware but metal will channel EM radiation, yes in all directions, even into your skull because it is in your ear. I'll just leave these here: Long-term exposure to microwave radiation provokes cancer growth: evidences from radars and mobile communication systems. www.ncbi.nlm.nih.gov/pubmed/21716201 http://www.emrnetwork.org/research.htm Title: Re: Radiation Free Air-Tube Headphones Post by: grue on May 28, 2013, 01:20:46 PM Unless you have issues with reading comprehension you will find the only claim I made is that earphones will channel radiation towards your skull. The rest were questions. So yes, you did reaffirm my statement. HOW DOES THAT EVEN WORK? You know what focuses radiation into a small area? SATELLITE DISHES! I have yet seen a wire that can amplify radio signals. And rightfully so, BECAUSE ANTENNAS DO NOT WORK THAT WAY. YES, antennas can absorb radiation and convert it to electrical energy and vice versa. But that does not mean a random piece of can absorb EM energy from your cell phone, convert it to electrical waves, then magically redirect all the energy to a specific place (your head). According to this logic, your precious faraday cages wouldn't work either, because they would just absorb the radiation, and reboardcast it back.Of course, this is all under the assumption that cell phone radiation is even dangerous. The metal is not just near your head, it is directly connected to a transmitter. I don't know if you are aware but metal will channel EM radiation, yes in all directions, even into your skull because it is in your ear. no, the 3.5mm jack isn't connected to a transmitter. why the hell would you think that?I'll just leave these here: Long-term exposure to microwave radiation provokes cancer growth: evidences from radars and mobile communication systems. www.ncbi.nlm.nih.gov/pubmed/21716201 Hey, if you want to quote studies, I can do that too.http://www.emrnetwork.org/research.htm In 2006 a large Danish group studied about the connection between mobile phone use and cancer incidence was published. It followed over 420,000 Danish citizens for 20 years and showed no increased risk of cancer (https://en.wikipedia.org/wiki/Mobile_phone_radiation_and_health#cite_note-Sch.C3.BCzetal2006-19) The 13 nation INTERPHONE project – the largest study of its kind ever undertaken – has now been published and did not find a solid link between mobile phones and brain tumours.[21] (https://en.wikipedia.org/wiki/Mobile_phone_radiation_and_health#cite_note-21) As you can see, there is no consensus on the dangers of EM radiation. But they, these studies don't matter because the only studies that matter to you are the ones that support your point. As far as tinfoil hats, I guess the World Health Organization wears them too... You do realize that iarc =/= WHO, right?IARC CLASSIFIES RADIOFREQUENCY ELECTROMAGNETIC FIELDS AS POSSIBLY CARCINOGENIC TO HUMANS www.iarc.fr/en/media-centre/pr/2011/pdfs/pr208_E.pdf http://www.who.int/mediacentre/factsheets/fs193/en/ Quote A large number of studies have been performed over the last two decades to assess whether mobile phones pose a potential health risk. To date, no adverse health effects have been established as being caused by mobile phone use. Title: Re: Radiation Free Air-Tube Headphones Post by: TECSHARE on May 29, 2013, 05:02:38 AM "Amplification" was your word, not mine. Funny how taking simple precautions about a subject that has no consensus yet (your words) either way is "retarded" (your words). A rational cautious person might call that inconclusive and err on the side of caution, but I guess that is "retarded". Funny how you like this argument when it suits you, but not the other way around.
Title: Re: Radiation Free Air-Tube Headphones Post by: grue on May 29, 2013, 02:51:16 PM "Amplification" was your word, not mine. Sorry for strawmaning. Let me rephrase my question. Can you prove that wearing wired headphones increases the radiation exposure to your head? If anything, I would expect it to decrease the radiation exposure, because the wire is absorbing the radiation.Funny how taking simple precautions about a subject that has no consensus yet (your words) either way is "retarded" (your words). A rational cautious person might call that inconclusive and err on the side of caution, but I guess that is "retarded". Funny how you like this argument when it suits you, but not the other way around. A rational person wouldn't randomly protect himself from non-existent dangers. There's no plausible mechanism why non ionizing radiation would damage your brain cells and there's no conclusive evidence that cell phone use is tied to increased instances of cancer. Hell, I can probably argue that a "rational cautious person", according to your logic should wear tinfoil hats while on a trans-Atlantic flight to reduce ionizing radiation exposure.Of course, this is all under the assumption that WIRED HEAPHONES INCREASE YOUR RADIATION EXPOSURE, which you have yet to prove. |
