After reading each article, they answered multiple choice questions to assess how well they had comprehended and retained the information they had just read. We began our study with a small pilot test something we highly recommend for all UX research studies.

Although it is true that cell phones emit low frequency magnetic fields that can be measured in milliGauss, they also emit high frequency microwave radiation which is what all the concern and publicity is about, and which the products below are designed to shield.

Many clients have contacted us seeking a shield for BOTH magnetic fields and microwaves for their phone. Such a shield does not currently exist.

Comprehension Scores: Slightly Higher on Mobile

To reduce your exposure to BOTH types of radiation, use an airtube headset and keep the phone itself at a distance. What does the number of bars displayed on the phone really mean. Not much at all. How To Test Cell Phone Shielding Products Cell phone, mobile phones, and cordless phones produce both magnetic fields and radiowaves microwaves.

Most cell phone shielding devices are designed to reduce the radiowaves. But you can test for either, if you wish. The tricky part about measuring the radiation from a cell phone is that the emission strength varies widely over time.

There will be strong bursts of varying intensity, followed by quiet periods. This makes it hard to compare "apples to apples". Also, because you are measuring up close to the source, you must use a near field meter AND you must maintain the position of the meter very precisely.

First, you must have a proper meter. To check for magnetic field emissions, an AC Gaussmeter will work. Most AC gaussmeters will have an internal probe.

Lighting Applications for Mobile Devices

Simply position the gaussmeter on the phone. Note carefully where the meter is positioned. Make a call and watch the readings. Notice the highest and lowest readings, and make a mental note of the "average" reading. Now, insert the magnetic shieldand repeat. To check for radiowave emissions, use an RF meter with Near Field antenna.

Again, position the antenna loop on the phone because the entire antenna stem has some sensitivity, it is best to position the entire antenna over the area that will be shielded.

Note carefully where the loop is positioned.

Now, insert the shield, and repeat. In general, you will not be able to completely kill a cell phone signal, unless you use extraordinary measures to attenuate the signal.

With a good connection, you will need an enclosure which provides a million-to-one reduction or better to prevent the phone from connecting. Radiation levels near the phone can be quite high. Using a headset to increase the distance from the phone to your head dramatically reduces your radiation exposure.

Long 39 inch cord with built-in microphone. Works with most phone models. Better than speaker phone mode as you can enjoy more privacy and put the phone down.

In , researchers at the University of Alberta found that reading comprehension was impaired when content was presented on a mobile. MOBILE DEVICE IMPACT ON STUDENT PERFORMANCE 1 Impact of Mobile Devices on Student Performance in an Agriscience Classroom Introduction One to one computing (), a scenario in which each student has an Internet connected.

In an effort to examine the broader impact of mobile devices on people’s lives, we presented cell phone owners with six separate impacts that might result from mobile phone ownership and these impacts were equally balanced between positive and .

How To Test Cell Phone Shielding Products. Cell phone, mobile phones, and cordless phones produce both magnetic fields and radiowaves (microwaves). Aug 31,  · What’s very important to note is that adopting a thought leadership approach to advertising on mobile devices will translate into measureable sales and sustainable lead generation.
