We've been hearing about it for at least 20 years (although the acoustic effect has been known since 19th century) - and no reliable effects have been detected. "Raising brain activity" is just pseudo-scientific mumbo-jumbo. It's just another gimmick used and promoted by "alternative medicine" crowd...I believe the brain activity thing, I mean clearly different people have different brain activity levels, and different from the "beats" this seems to make sense. I might butcher it as I don't know the technical definition, but my understanding is basically just a measurement of how active your brain is at any given point, obviously you are going to be thinking more critically and using more of your brain when pondering a bold question like "what is life" than you would when sitting lackadaisically in a class room half paying attention to the teacher reading a section of your science book on micro-organisms.
Obviously there are people who use their brains much more than others throughout the day, regardless of "IQ" levels. To me, "Brain Activity" is simply the measurement of this.
