Hot ears from phone

RichardCam

I have heard about air tube headsets for mobiles - I have been told it stops hot ear and cuts down the radiation. Can anybody tell me any more?

"Reduces 98% of Harmful Radiation Emissions Generated By Cellphones"

I am no expert, but I think this is bu11shit.
It cannot reduce Radiation Emissions Generated By Cellphone.
Any headset reduces your head exposure to "Harmful Radiation Emissions Generated By a Cellphone"

I have been reading up on this.... Why then does it say in the instructions for my iPhone to keep it an inch from the body when switched on... If you can use the phone without it being pressed up to the ear, it must be better. The air tube headset coverts the electrical signal to plain airwaves like a doctors stethoscope. I would rather have that than the phone or a wire from the phone against my head. I don't think that is bu11shit. Rather be safe than sorry!

If that is the case, why are you carrying a radio tranceiver that operates in the microwave band to start with?

Because:

• The frequency is much lower;
• The power is much-much lower because of the very small distance;
• You carry the receiver close to the body, not the transmitter.

Anyway, I don't see any difference from a wired headset.

your ear gets hot cuz u are pressing a object to it. thats all.

1800 Mhz ain't that far away from the 2400 Mhz that a microwave oven works at, and 1800 Mhz is widely accepted as microwave.

Erm, the phone is a transmitter as well as a receiver.

Because my friend, it seems some iphone users are gullible , stupid or both!
Your ear is bound to get warm when using the phone, the skin allows cooling of the body, if you have a handset pressed against your lobe, it's not going to cool so effectively is it?
So apply a little common sense or, spend your monies and get the pintless device

The 'idea' of "air tube headsets" is to remove this transmitter away from the head (and the body) and to stop the high frequency being transmitted (apparently) through wires, especially during the conversation when the transmitting power is maximum.

What I mean is that a wireless receiver with earpieces working on a lower frequency can be safely positioned close to the body. Both the frequency and the power of the connection between the receiver and the phone will be lower. Standard wireless headphones work on 860Mhz and they only receive, not transmit.

I see now that these "air tube" devices mainly use wired connection between the phone and the acoustic device.

Thought bluetooth worked at 2.4ghz, but from my college days iirc lower frequencies are more penetrable, but in anycase I think the OP is worrying over nothing as the BTS and other equipment he passes may radiate more than his handset

I don't know what BTS is, but to be fair you cannot compare the equipment that you pass with the handset that you press to your head.

The power is inversely proportional to the squared distance.
