In addition to the great lighting, the new design also has much improved acoustics. The sound dampening is impressive. I can have conversations without straining to pick up words through the din of echoes, and the ambience has a nice warm sense of quiet.

FAA through the National Academies did a research study a few years ago [1] to provide guidance on improving the intelligibility of PA systems and also improving the overall acoustics of airport terminals. The idea is that this guidance would be used for terminal renovations and new construction. It looks like they may have put this to use! (I was on the team but not an author of the final report).

I'm really glad that recognition of acoustics in airport design is gradually gaining steam. As a Seattle resident I'm pretty jealous of people who fly through SFO regularly, because that airport is a joy to wait in because of how quiet it is. Now apparently I get to be jealous of PDX as well.
