The architects of the Hong Kong airport paid a lot of attention to sound I think. The ceiling is very high but there are panels that are at various angles that help reduce reflections. The first time I visited I noticed it right away. As a result I've found the airport to be a very peaceful space. It's calming and relaxing.
