Reply to a patient asking about possible health risks from hearing aid use radiation:

“Hi, well this article you sent me is interesting…  however here are the facts:
 

 
Hearing aids in normal operating mode emit around 0.0000025 watts, whereas a typical mobile phone power output is 1 watt. i.e. a hearing aid emits approx. FOUR HUNDRED THOUSAND times less heat / EMF (Electromagnetic fields) than a mobile phone. So, straight away we can say that using a hearing aid to take calls is arguably safer as you are keeping your mobile further away from your ear.

The relative amount of RF (radio frequency, a form of electromagnetic field) energy absorbed in the head of a wireless communicating hearing aid user is given by the Specific Absorption Rate (SAR). The US Federal Communications Commission (FCC) requires devices generating RF energy that are used by the general population to have SAR levels no greater than 1.6 watts per kilogram. The SAR level for a typical wireless hearing aid is 0.00142 W/kg. This is approximately 1125 times lower than the FCC safe limit. Bear in mind that RF non-ionizing radiation is very unlikely to be harmful. Other types of non-ionizing radiation include normal visible light!

Furthermore it could be argued that streaming the signal from a mobile that is not near the body reduces the risk of EMF radiation and heat near the brain considerably (see below). I love talking about this stuff, but I hope this reassures you. We do have 1 lady that reported a cessation of headaches when we switched off the wireless functions on her hearing aids (but that’s one out of 4000)…

Here’s some info from the US FDA and Starkey Hearing Aids:

Perhaps poisonous Radon Radiation is far more concerning? And it’s typically in the ground you are living on! This is very high in the Peak District, most of the Dales and medium-high in Leeds!

Please bear in mind that the very website you were reading is selling (and directly connected to) an EMF ‘neutraliser’ of dubious scientific status for $1000. And that there is a multi billion $ market in alternative health (inc. EMF avoidance).

And here is a piece about Bluetooth headsets: From the Jabra Blog:

“Radiation from Bluetooth headsets:

Unlike cell phones, which have to transmit a signal to an antenna that might be many kilometres away, Bluetooth headsets only need to reach the phone in your pocket. Most Bluetooth headsets have a range of only 10 meters (30 feet). This also means that they emit far less radiation than cell phones themselves. How much less? One thousand times less.

That’s why most authorities explicitly advise using hands-free devices including Bluetooth headsets if you’re worried about radiation exposure from cell phones. For instance:

“To reduce radio frequency radiation near your body: Get a hands-free headset that connects directly to your phone.” – Center for Disease Control and Prevention. This could be a hearing aid of course.

“Headsets can substantially reduce exposure since the phone is held away from the head in the user’s hand or in approved body-worn accessories.” – FDA / Food and Drug Administration

“Use the speaker mode on the phone or a hands-free device such as a corded or cordless earpiece. This moves the antenna away from your head, which decreases the amount of RF waves that reach the head.” – American Cancer Society

…In a nutshell, if you’re going to be talking on a cell phone no matter what, using a Bluetooth headset will help you reduce exposure to radiation.” This would include a hearing aid, such as Oticon Opn, Phonak Audeo B-Direct or Resound LiNX 3D.

I hope this helps,”
