It is what I call *dirty air*.
That are frequencies between 5kHz and 10MHz, up to 30 MHz.
I use special measurement equipment to measure them.

I measure them emanating from monitors (f.i. my earlier 26" Acer with a heavy peak at 4,5MHz), and from keyboards.
I now have a Philips 27" monitor.
I had a USB keyboard connected via a USB/PS2 cable to my computer. This connector USB/PS2 gave a lot of *dirty air*, so I connected the keyboard to a USB hub.
However, I found at several different heights above the Trust keyboard also *dirty air* layers.
This was avery strange phenomenon, because normally the fields should be according a slope line, and not a layer of low, a layer of higher, a layer of lower, and a layer of higher field strength.
I exchange it for a Microsoft wired 600 keyboard.

It matters also if the cables to keyboard or mouse are shielded or not.
When the wires are shielded, at the keyboard and mouse, one may experience problems.
When the wires are not shielded, less problems may occur.

Br aware that electrosensitive persons may react to very tiny, sometimes hardly measurable fields.

Next to this problem are the longitudinal waves, which are biological very active.
They can be reflected succesfully.

The biologically effects are experienced as good.
