There are cars, trucks, motorcycles; there are loud stereos; there are noisy neighbours and a lot of other things. It occurs to me that I've slept in a few hotels at airports, and I can sleep very well because they are built not to let that sound in. So we need to look at home construction standards. Perhaps, as well, there may be an experiment to be had with what you might call active acoustic sound control, like the noise-cancelling headphones you can wear that totally obliterate all outside noise. These are getting more sophisticated and more effective, and there could be a community experiment where we actually allow people to try these and see if their sleep improves, especially.
We have airports, flight paths and runway usage that have to be considered. We have aircraft, the flight techniques and the design. I understand there is one brand of Airbus that could use some retrofits, and Air Canada is going through that process with its fleet right now.
We have regulations with respect to operating hours, and that has to be part of the mix. You mentioned, Dr. Kaiser, that municipal planning, airport location and development along the flight paths have to be much better managed, and as we look at new airports we have to keep the municipalities from growing around them. We should have learned something by now.
Then, finally, when it comes to home construction, there is much more we can do with respect to soundproofing and, again, sort of acting on the personal and active sound control that you can apply in a building and individually.
Again, it's the other sources. This isn't just an airport thing. If the airplanes went away, you'd start to notice a lot of other noises as well.
I'll just conclude quickly here by saying that the challenge is for the complete circle of suggestions. This isn't just an airport issue. It's more a quality of life and community issue that needs a complete 360° look.
Okay, that's it. Thank you.
