Hmmm. This sounds strange. Lets assume that your friend is
really not crazy. I doubt that the person concerned is using
microwaves. In fact just yesterday I read an article in a
German journal which claimed that the damage caused by
microwaves is caused by the heat. They cited the case of a
german radar technician who walked inadvertently walked in
front of an active NATO radar aerial. His blood clotted and he
was rushed to hospital. He died of two heart attacks caused by
his thickened blood two weeks later
(i.e. not immediately). Now its not generally disputed here that
microwaves will harm genetic material, but that would only be
noticed if he has kids. It would certainly not cause "strange
vibrations".
Ultrasonics - well maybe but they really cause pain in the
inner ear and its a bit difficult to focus the sound in a
buildt up area due to the reflections etc. Now this means that
the person who uses the ultrasonics is likely to get a dose
himself which is not a pleasant experience. The pain in the ear
is tremendous (knocks you down).

So my guess is he uses sub-sonics. These can certainly make you
feel awkward and cause headaches, depressions etc. However
their directionality is a lot worse than high frequencies.

So to sum it up: there is little a nasty neighbour can do to
make your friend feel that way. There may be other things: have
you got a subway running under the house ? Or a big water mains
? Or something like that ? That may be the reason.

Hope I have helped. If it does not get better your friend
should move.
That should help.

Bye,
