Here’s a link that anyone interested in understanding sound transmission in housing may appreciate.
I took time off work today to take a class of students to the NRC Campus in Ottawa to visit the testing labs and working models.
The site is open to the public but tours do require bookings in order not to disturb ongoing experiments.

Thanks, Gabe. A helpful site. Nice that they quantify their suggestions (with percentage transmission, etc).
If you ever visit the city David, I'll personally make sure you get the full tour.
You'll get a kick out of the test houses. Each one has over 7 kilometers of wiring conected to calibration computers. Eventhough the houses are empty of people, the entire house mechanical and electrical appliances duplicate the average family. In other words, the shower comes on at the right temperature for a pre-programed lenght of time, the stove comes on at meal time, as do the kitchen exhaust systems etc.
This way the model lifestyle is duplicated exactly the same way each day. This makes comparisions more accurate between heating systems or a/c systems. If some company wants them to test a new furnace, they have a benchmark to calibrate with in real life situations.
Kinda neet actually,

I have an image of a squatter in that house. He'd have to jump in the automatic shower at exactly the right time, make sure all the soap is rinsed off in 7.2 minutes later, then run downstairs to catch the toaster during its cycle, etc.

Well thanks a lot.
Now I'll have to move out before security gets here.
Dam it.
