YES. I was thinking the same thing. The last building I was in was converted from an old industrial space. There were noise cancelling devices in the ceiling. You couldn't hear the person sitting across the table from you.

Noise canceling? Got a link? I am aware of white noise machines but not noise-canceling. Presently building out a new office and would love to see details.

I'm not an acoustical engineer but my understanding is that noise canceling devices are usually passive - think of the oddly shaped foam panels you see in recording studios: https://www.google.com/search?q=anechoic+chamber&source=lnms...
Or, in an extreme example, the ones you see in anechoic chambers: https://www.google.com/search?q=anechoic+chamber&source=lnms...
The foam devices serve to both absorb sound energy, and to scatter the remaining sound energy at a variety of angles, where much of it will collide with other reflected sound waves and cancel out.
I needed some acoustic foam for a small project at home and found this place. They seemed pretty affordable (and had lots of colors) compared to other places, though I'm far from an expert and I was only buying ~$40 of foam so I didn't exactly spent too much time comparison shopping: http://www.foambymail.com/acoustical-foam-products.html

I'm pretty certain he means noise dampening, and you knew that.
