It looks like it would work on things with a tube or barrel but not sure how that could be applied to cubicles or shop noise unless you made round doorways between them or something.

Edit: plus in the video it looks like that device went inside the tube and had a smaller ID. If that is required then would it wouldn't work for guns or markers.
