<br>
I do actually experience tinnitus of this sort - I find it quite hard to=
 compare it with, say, a tone from a signal generator, but it does seem to=
 be in the vicinity of 9kHz, give or take a kHz or two. But as I also live=
 within 1km of 4 high power broadcast transmitters, (not to mention the am=
ateur radio related fields ;-)) I can safely say this kind of =A0RF field=
 does not make any difference to the sensation. Also, I have spent a fair=
 amount of time in screened rooms, and can say that makes no difference ei=
ther... if anything, a screened room often makes it more noticeable becaus=
e the ambient noise level is quite low inside them.<br>
