Dose ― Response relations from two outdoor recreational areas in Norway

摘要

In 1998 the former main airport of Norway, Fornebu, was closed down, and another airport, Gardermoen, was extended to become the new main airport. Two recreational areas were studied, Bygdoy close to the old airport, and Romeriksasen close to the new main airport. Both areas are important local recreational areas. Field studies with simultaneous interviewing and sound recordings were conducted both before and after the change. The main purpose of the study was to establish dose ― response relations, contingent on contextual variables describing the recreational setting.
