Way above my pay grade, Sound waves no longer transverse or perpendicular?


Interesting, thought provoking (for some) paper on sound waves and the new wave of sound.

I am a bot thirsty for knowledge and useless information.

Boundaries can be placed inside a container so they can be made to actively generate  shear thru discrete porous surfaces and then realigned to increase laminar flow through and around those same boundaries. I have applied some of these principles to my audio room for a couple years now. This paper partially explains the reason why my application works. Tom

@theaudiotweak for sure but that's my point.  You can (did) place real  physical boundaries etc and generate that vector redirection.  Not seeing what that is this doesn't mean you produced shear in air.  Producing laminar flow isn't a shear/compression thing.  It's lack of turbulence.  And you urely didn't "envision" those boundaries and make that happen in a mathematical model.  This researcher modeled air to act like a solid by contriving a set of boundaries and voila, it passes shear (mathematically).  You actually do something physical by your description.

My workarounds are conceived because of the transition of shear waves to compressive and their repetition of form and inner action. I am fascinated with the concept of a reactive boundary layer on a surface and the turbulent air on that boundary and the resulting sound it makes. This published article which I received a few days ago with its illustrations has helped me conceive a couple other ways to overcome boundary interference while increasing laminar flow.  Now to experiment and listen some more.

That boundary layer is like a purgatory between heaven and hell.

Trying to work with and make it sound heavenly at least to my ears.
