This topic has been researched in great detail in various quarters, I
believe - in the UK and US. The types of patterns that create different
effects, different energy levels and their effects, different spectral
characteristics and their effects, etc. And I do not believe this is a
recent effort either. All classified, of course. If not, people would be
outraged and shut it down and outlaw it just like in the case of Nazi
eugenics. A lot of researchers, psychiatrists, psycho-guys, technicians,
engineers, planners, etc. would be out of immediate work to do.
