Project: Aircraft noise annoyance in Norway

Project: Aircraft noise annoyance in Norway

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.

MOVE: Monitoring the noise from individual vehicles in traffic

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.

Hva er egentlig trykk?

Hva er egentlig trykk?

Lyd er noe vi alle har hørt om. Det vi oppfatter som lyd er variasjoner i lufttrykket på trommehinna. Disse variasjonene forplanter seg dypere inn i øret og deretter inn i hjernen. Trykk er derfor sentralt for akustikere og alle andre som jobber med lyd. Her vil jeg minne deg på hvor lufttrykk egentlig kommer fra, og si litt om hvordan lufttrykkets natur begrenser hvor bra øret og mikrofoner egentlig kan bli.
