Hi Marc,

I dont see any difference...

Ok so when they don´t resonate...they will reflect...like a wall for
example
but as soon as any human being with ears gets inside the beam or a
reflected beam ..they will hear
the modulation...isn´t that what HSS demonstrates ? ...infact that is
the whole idea of HSS

So it wont work they it should because everyone in the restaurant will
hear the noise
...what is wrong with that conclusion ?

commercially, at least for rooms.

It would be helpful if i could find anything on it...but i don´t.

Thanks again
