"Like any boundary intersection the Holographs will react differently to drywall, plaster, glass,wood,book cases,record jackets. They all have a varied shear velocity and shape or contour that will react differently to the varied shape and shear velocites of the Holographs."
Wouldn’t it be better to make them from one wood/material depending on the wall surface one is placing them next to?
Even if four different woods are used, how does it go if a person has a plaster wall with a painting hanging on it? Or two paintings, one covered with glass? It may end up in any number of combinations. How to assure that whatever shear wave from a certain material will hit the right area of the Hallograph? How does that work?
Do, let’s say, GIK room treatments increase or decrease the perceived benefits of Hallographs?
What scientific methods could be used to verify this performance? Where does one even start with that?
By the way, Shakti website mentions "patent pending" which is about what reviews from 2003 mentioned, too. What happened with that?
