It affected everyone in the room and to a lesser extent the next rooms over if the door was open.
Obviously, we did not shelve it right away since there seemed to be no permanent effect. Some people were really creeped out after they had been exposed in my first try. But this is an engineering lab, so soon enough the lab was filled with cowboys wanting to experience it and trying to figure out how it works. Meanwhile, the more safety minded people took a short break and went for some air outside.
We stopped after the professor figured out something odd was going on on his floor.
I wonder what the physics behind it is. I guess if you have an aquarium of water with low frequency waves and overwhelm it with high frequency waves, you wouldn't be able to see the low frequency ones any more. Presumably (IANA physicist) it's the same thing but with sound waves.
