How To Use Noble 1, The RfReduce Device.
You can use our Noble 1 RF reduction device when you have a wired earpiece/microphone connected to your Cell Phone. One approach to using our device will be to put your Cell Phone on your belt and have the wire for the earpiece/microphone coming up to your ear. In the figures below we show our model wearing the Noble 1, as well as a diagram showing the placement of the Noble 1 half-way between the chin and the waist.
Let's ensure that the different parts on the photo are understood. We will start at the top.
At the very top of the ear piece wire is the little earphone that inserts into the ear.
As you come down the wire, you will see the microphone that picks up the voice of whoever is using the Cell Phone.
Continuing down, you see a clip that is attached to her shirt pocket. This keeps the ear piece wire from bouncing around too much and it also holds the weight of the lower part of the wire and the weight of the Noble 1.
Below that you see the Noble 1 that has been attached to the ear piece wire, as will be discussed and demonstrated, below.
At the very bottom, of course, we have the Cell Phone.
Open The Device.
The device is a clam shell arrangement. There are 2 small plastic clip/snaps that hold the device closed. Carefully push the clips away from the device and open the clam shell.
Close The Device.
After running the wire through one or two times, snap the clamshell shut and be sure not to pinch the wires. You want the clamshell to be fully closed to get the maximum effectiveness. If you can't get the earpiece wire to pass through twice, don't worry about it. It is important that the Noble 1 device be fully closed.
Leave It Closed.
Once you have clamped the clamshell closed, you will probably leave it just like that for most or all of the time that you are using it.
Plastic Hinge.
You may notice that the hinge on the Noble 1 device is plastic. If you open and close it many times it may eventually break.
FAQs: Answers by Robert Palma
How The RF Of The Cell Phone Tries To Get To Your Head
The antenna of your Cell Phone is radiating Radio Frequency (RF) energy into the space around it. All RF energy has a wavelength. The wavelengths of Cell Phone RF are quite small, and are therefore referred-to as "microwaves". Some of this RF (microwave) energy couples into (gets onto) the earpiece wire that is going from your Cell Phone to the earpiece that is positioned in your ear. The wire, usually of a primarily copper construction, is quite happy to carry the RF. It can carry it reasonably efficiently up to your head. All that wire has to do, is to carry it more efficiently than the same RF would travel through the air to your head, and we have the situation where using a wired ear piece has worsened (increased) the radiation level at your head.
We have made specific measurements of the coupling of the RF to the earpiece wire. Said another way, we have measured, in our microwave laboratory, how "well", how "much", the RF that is coming off the antenna, can get into the earpiece wire and therefore travel to your head. By the way, a "microwave laboratory" is a laboratory where various microwave frequencies can be generated and measured.
We have found that, approximately 10% of the radiated power can couple into the earpiece wire. This is a fairly high number. Said another way, "it's a lot". By using the Noble 1 device, this "a lot" can be reduced. The Cell Phone is, in effect, "trying" to get the RF to your head by traveling along the earpiece wire, but the Noble 1 reduces the RF intensity by 90-93% depending upon whether the earpiece wire is passed once or twice through the Noble-1.
Using A RF Reduction Device At The Bottom Of The Ear Piece Wire - This Is Non-Sense.
We have seen competitor’s recommendations that show the use of a RF reduction device, around the ear piece wire at the bottom of the wire. In other words the RF reduction device is very close to where the earpiece wire comes out of the Cell Phone. This does not make sense. This is a testimony that the person or organization who is suggesting to use their RF reduction device in this way has a fundamental misunderstanding of the physics of this phenomenon.
Cell Phone manufacturers ensure that there is no RF leaking out of the earpiece jack. The problem that occurs is that the radio frequencies that are radiating from the antenna, through space, are coupling to (getting onto) the earpiece wire. The RF reduction device needs to be above the antenna, not at the antenna or below the antenna.
The Air Phone - Is This A Good Idea?
There is a Cell Phone earpiece that is referred-to as an "air phone". It has a wired connection to an audio transducer module. From this module, a hollow tube brings the sound to the ear. The tube is plastic. The idea here is that the tube will not conduct the RF to the person's head.
We are often asked whether this is a viable approach to reduce Cell Phone RF to the head. As long as the length of the tube is such that it extends down to a location that is approximately 1/2 of the distance from the waist to the chin then this approach is effective. Some of these products that we have seen are sized so that the air tube only extends from the ear, down to the chin (of the person wearing it). If you are going to use such a device you might consider trying to get a model that extends the tube down to a point that is 1/2 way between the chin and the waist (of the person who is wearing it).
It may be a bit more bulky and heavier then our Noble 1 device. It's cost might be more, as well. We also feel that the use of a tube to conduct the audio frequencies will give a bit of a "in a barrel" sound and therefore the receive audio will most likely be a higher quality with our Noble1 device and a conventional wired ear piece.
You could also use the Noble 1 device on the wired portion of such a device to increase the effectiveness of the whole system (air phone + Noble 1) for the reduction of RF to a person's head.
Are Speaker Phones A Good Idea?
We are often asked whether use of the speakerphone feature of a Cell Phone can reduce the RF getting to the head compared to holding the phone to one's ear. The simple answer is "yes". Your "transmit audio quality" is what the person on the other end of the call hears. Transmit audio quality using the speakerphone feature of a Cell phone is not all that great, but if you speak up, and the noise in your environment is not too high, it can be an acceptable approach.
BlueTooth Wireless Earpiece - A Really Bad Idea
You may have seen people wearing an earpiece that has no wires connected to it. In addition, this device has a microphone as part of it. This is most probably a BlueTooth wireless earphone/microphone.
BlueTooth is the name of a specific type of wireless (Radio Frequency) technology. BlueTooth uses specific frequencies, and communicates using specific protocols. It is intended for wireless connectivity over very short distances - less than 10 meters. Mostly it was intended to allow various computer peripherals (keyboard, mouse, etc.) to wirelessly connect to the PC.
The BlueTooth approach for Cell Phone usage, uses a BlueTooth transmitter in the Cell Phone and a BlueTooth receiver in the ear piece so that the user (the person wearing the BlueTooth device) can hear the other party on the Cell Phone call. In addition, and here comes the problem, there is BlueTooth transmitter in the ear piece that communicates with a BlueTooth receiver in the Cell Phone so that when the user speaks, his/her voice will be connected to the Cell Phone.
If a BlueTooth device is used for the convenience of not having wires coming from an ear piece to a Cell Phone that is, say, on the user's belt, well then it could be more convenient … in a way. Of course you now have another device to buy batteries for (The BlueTooth earpiece).
If the BlueTooth device is being used to keep the Cell phone radiation away from the user's head, then this is an insane idea. There is a BlueTooth transmitter in the BlueTooth device! The radiation from that BlueTooth device is in the user's ear. It's in his/her head!
Also, the BlueTooth frequencies, are closer to the optimum frequency for heating biological tissues. BlueTooth frequencies are in the same band of frequencies as microwave ovens.
We have heard arguments that the power of the BlueTooth transmitter that is in the ear piece, is less (power) than that of a Cell Phone. While this is probably true, since BlueTooth transmitter is so close to the persons head, one would really be defeating themselves in using a BlueTooth earpiece for reducing RF to the head.
All in all, it a user wants to reduce RF to his/her head, a BlueTooth wireless earphone/microphone is a dreadfully bad idea.
What About Protective (Metal) Bags?
We have been asked to comment on the metal bags, and electrically conductive fabric bags that are sold to enclose the entire Cell Phone. Oh dear!
If the cell phone were leaking significant RF and you wanted to reduce the RF to your torso, you could use such an accessory, but it could easily alter the thermal design of the Cell Phone and the phone could overheat and malfunction.
If the bag encloses the Cell Phone antenna, the phone will not be able to connect to the Cell Phone tower. In other words it won't work.
If it is your intention to reduce RF to your head, we cannot think of any reason to use such an accessory.
What About Protective Crystals?
We have been asked to comment on the "crystals" that you can glue to the back of your Cell Phone to some how make the RF radiation be nullified.
We have visited the web sites of such products, and found statements on the site that fairly clearly stated that there is no data/information to show that they reduce RF radiation at all. Our approach to reducing RF to a person's head is based in the traditional (classical) discipline of electrical/electronic engineering (the application of classical physics). We do not know how to measure or quantify the effects of these crystals so we can't offer an opinion on using them, or not using them.
