Spurred by your hint....I found they have many "Colors" of NOISE! I think your
neighbors might fall under Orange noise [noparse]:)[/noparse]

Thanks for the info!
Found a neat clock that does the White Noise and even has a "sunrise!"....he

an OT remark...I guess you mean pink noise...it is what is being used in
noise 'cancellators' or whatever they are called...white noise is harsher,
rather unpleasant to listen to, pink noise is closer to surf sounds...I
have been using it to block out tens of students practising simultaneously
in the music across the street of a room where I do a lot of reading
