It would take something like a the engine of a jet aircraft to demolish a wall.
Even if you could miniaturise the jet so it could be hand-held, the user would be propelled backwards when they activated it , if they could hang on.
I used the diagram as an example. Assume sound was being projected at a different frequency and intensity and the wall is constructed of a piezo material.
