^^ Many people can't tell when a transmitter is on, but some can pick up a cell phone from a hundred meters away, because they are too sensitive and have to live in radio isolation. It was recently discovered that about 25% of people can find magnetic north.
Sounds like a handy ability ...

A lot of unsupported (and unsupportable) claims in this thread...

There is always far less turbulence in a debate if neither side has a large financial interest.

Of which WIfI frequencies are exactly that. Aluminized materials work well . even Paint . Less density of the material less effective.. shiney fabrics occasionally of made of metallized materials will block infared pretty well also .. Consolidating radio frequencies can have a bad effect on the equipment generating them.. but only if immediately like wrapping the output antenna up .
depending how the equipment is built. obvious microwave oven equipment is made to survive these situations well.
Faraday cage type situations can be used to protect from radio frequencies as well as force them to stay in a particular area. Buildings that are build of wood and plaster will absorb rather than consolidate a electromagnetic field.
There are metalized fabrics that some companies are actually making clothing out of .. They find the hoodies they manufacture are a big seller. These can reflect a large amount of radio frequencies away from them . just FYI and yes was a ham radio electronics tech . And operator at one point in time . Amongst other hobbies grew up around.

I can still hear florescent lights. Is a headachy sound. I thought everyone can hear them?
NOPE....... i can only hear them sometimes if its really quiet, real nuisance
but the light they give off and the sound gives me headaches. even some of the new LED replacements lights . the brightness gets to me at night... Have had to leave some businesses cause of both of these types of lights
If your gonna get stuck in a situation , where you don,t have a choice put yourself next to the nearest natural light source a window , whatever .
or do not put yourself through being stuck under these kinda lights if you can help it.

Ooh. You can hear the new lights as well? I am glad it is not just me!
The only lights I got on with were the older traditional bulbs, and especially a bulb known as a daylight bulb. Not been able to get another locally though since Maplins closed.
