Institute for Research in Construction
National Research Council of Canada
Those of us in the US owe the Canadians a real thank you for establishing and operating the only significant independent research laboratory in architectural acoustics in North America. Much of what we know about architectural acoustics especially as it relates to residential and commercial construction for sound isolation has originated in their laboratories. Their work concentrates on sound isolation between spaces, isolation from the outdoors, and speech privacy, occasionally touching other topics. They have a very large library accessible online. In the past we have provided direct links to a large number of important papers. Unfortunately, they are in the habit of changing their website frequently so that the links no longer work.
Thus, for now, we will provide only this to their search engine that will search their library for all their publications. There are thousands of them even just in acoustics, but also in dozens of other areas.
