Amsterdam Airport Schiphol is located in one of the most densely populated areas of the country, and aircraft noise is a problem in the surrounding cities. Low-frequency ground noise created at take-off is especially difficult to combat because standard noise barriers are largely ineffective against it. Schiphol is implementing acoustical landscaping in the form of large ridges that dampen longer wavelengths.
I have the benefit of living in a suburb with plenty of tree cover. In fact the view outside onto the streets is almost as if the street is a parkland. The concept that any suburb should have an abundance of trees and shrubs and associated bio-diversity is simply so logical that one wonders why would anyone think otherwise.
Having driven down many highways and sometimes wondered about those large arrows that point down, I was interested in a story from the Netherlands.
