Subliminal suggestions, both visual and audible, have been used in advertising for decades. This is nothing new. It has been shown that by placing an attractive model next to a new car or other product, you sell more than without this type of advertising.
Subliminal suggestions to change a persons behavior has been profoundly non effective. It just doesn't work. This is the premise of the movie "The Manchurian Candidate".
The difference between my two examples are that the first is behavior of a large group of people to influence trends. The second example is about deliberate behavior of one single individual. There is a big difference here.
Waves of any type will not change a persons brain. We have free choice in the matter.
