Thats the advantage of the infra-sound plant... There is no obvious problem.
Just a gradual degradation of their quality of life with no apparent cause.

Getting power to it would be the hard part, but you could probably plant it somewhere in the basement nobody ever goes. Plug it in beside the furnace, and stick it inside the ventilation ducts so the sound emanates all over the house.
