Sound in the broader urban context Ronny Klæboe

Background  1980’s  Norwegian regulation: Large infrastructure projects should document their consequences  Heavy investments in ring roads and tunnel projects  Typical for road and rail traffic – multiple consequences  Challenge – noise and air pollution treated differently  1990’s  Research at multiple time-points in quasi experimental settings document consequences of rerouting traffic  Harmonisation of outcome indicators – also annoyance from air pollution  Parallell good quality socio-environmental studies of both noise and air pollution Page 2

Traffic  Noise  Population dynamics  Vibrations  Social composition  Air pollution  Unsafety  Visual aesthetics  Intimidation  Visual disturbances  Insequrity  Confiscation of space  Willingness to invest  Barriers Page 4

Results  People exposed to air pollution are more likely to be annoyed by noise and vice versa people exposed to noise are more likely to be annoyed by air pollution  Noise sensitive persons react stronger, not only to noise but also air pollution => Noise and air pollution have combined effects Page 7

Combined impacts can explain overreactions to noise reductions Page 8

Future research  Need multi-site studies stratified  Need to analyse changes over time  Need different contexts  Not possible to cover all aspects in a single study  Matrix of combinations to be populated  International scope, shared data over time  Cooperation platforms  Contributions from monitoring pollutants  Contributions from apps Page 16

We need international urban sound big data platform  Challenges – handle large number of records associated with new apps and monitoring (not necessarily many TB)  Ensure equal rights owner-ship – not hosted at single organisation making others secondary citizens  Enable European and world-wide access and networking  Platform should serve as repository for multiple Web-sites, blogs, data-bases, calculation software etc.  Governance to promote coontributions and negotiate conflicts between producers and consumers of data  Rules for co-authorship, first-publishing rights etc. New hyperconvergent «Meta-cloud» solutions managing both remote and local clouds using web-based hypervisor software are able to solve ownership problem since whole structure can easily be cloned to institutions vishing to join and updated nightly Page 18
