Cheers ....will give the pink noise a go.....much along the lines I was thinking.

I can live with placebo ......but  not everyone knew the unit was in use or even that thats what was being listened to....ie partners of people visited ..that came in and commented at the sound change ...obviously only anecdotal ...but more than one did.
