NAVCANADA is proposing AVG 55-60db which means some planes will be 70% higher
Great study by a Simon Fraser professor. https://academic.oup.com/aje/article/163/1/27/84998
Another study by an SFU Prof. https://academic.oup.com/aje/article/175/9/898/173624

Purple represents avg dB noise of 55db but will likely be consistently closer to 60-65db, Light Blue represents avg of 60 dB but likely higher as well.
Vertical lines means more noise than before. North burnaby residents likely less affected as planes will be at higher altitudes.
The white lines re the new approximate flight lines, but pilots have broad discretion to fly in the areas around those lines as needed.
