She has tried earplugs + earmuffs, no joy

Also, most people will find that you get used to a constant noise. She's
tried music and white noise (one of those "subliminal message" ***
tapes with the waves and the seagulls") to try and block it out

Unfortunately that wasn't a complete success because the only tape
she could find was a New Agey one with a choir and other
distractions. I could make a white noise CD or mp3 though, that
hadn't occurred to me until now

> How far away from the antenna must she get to lose the audio ?

Good question. Don't know. Poor answer

Having another chat with her tomorrow

*** not the "You will hear an irritating and inescapable tone" one ;-)
