Imagine that a new road was planned for construction close to your house. Naturally, you might want to know how much this would impact the noise situation in the area where you live. Currently, what the developers would be able to tell you are numbers called equivalent levels that describe the noise increase in your area. While these numbers may be based on excellent simulations and may be entirely correct, numbers are no substitute for listening!
Aircraft noise unquestionably causes annoyance, but reactions to a given noise exposure vary wildly. The Norwegian Defence Estates Agency and SINTEF ICT Acoustics have teamed up to strengthen the connection between the aircraft noise situation and the annoyance response of airport neighbours.
For this purpose, we have assessed annoyance due to aircraft noise in Norway, by conducting noise annoyance surveys near five Norwegian airports. Respondents were asked about their annoyance from aircraft noise directly, but they also got questions that were more specific, like:
- When during the day are you most annoyed by aircraft noise?
- What kind of flight activities do you consider specifically annoying?
The aim of the research project is to use the obtained data to explain why respondents in different communities respond differently to the same noise dose.
In the research project MOVE, ARC is investigating methods and systems to estimate the environmental impact of road traffic. The project is financed by the Norwegian Research Council, through the BIA program. MOVE is managed by Acoustic One/Norsonic AS and SINTEF; other partners are NTNU and Norsk Elektro Optikk AS (NEO). The project started in 2012 and will be finished in 2015.
