  1. 1. An IoT Solution for Urban Noise Identification in Smart Cities : Noise Measurement and Classification

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Yasser Alsouda; [2019]
    Keywords : urban noise; sound pressure level SPL ; internet of things IoT ; machine learning; support vector machine SVM ; k-nearest neighbors KNN ; bootstrap aggregating Bagging ; random forest; mel-frequency cepstral coeffi-cients MFCC ;

    Abstract : Noise is defined as any undesired sound. Urban noise and its effect on citizens area significant environmental problem, and the increasing level of noise has become a critical problem in some cities. Fortunately, noise pollution can be mitigated by better planning of urban areas or controlled by administrative regulations. READ MORE

  2. 2. How smart are smart cities? : How can big data influence the planning of sustainable urban mobility?

    University essay from KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Author : Luiza Teixeira Betarelli Cabrera; Angela Marie Woda; [2018]
    Keywords : Urban mobility; sustainable development; big data; innovation.;

    Abstract : The opportunities we have to move around the city, otherwise known as urban mobility, are intrinsically linked to both local industrial output as well as the physical possibilities of moving provided by the landscape of the urban environment. With the advent of automotive congestion solidifying itself as a reality as populations in urban centres continue to rise, the conspicuous question is: If we continue the way we’re going, what happens next? This thesis explores the influence of new technologies and the data that drives them on the mechanisms of planning mobility in urban centres, as well as the potential of adoption of innovative mobility solutions that address environmental concerns through insights that higher resolution data can provide.

  3. 3. Distance Attenuation of Tram Noise in Open Urban Areas

    University essay from Chalmers tekniska högskola/Institutionen för arkitektur och samhällsbyggnadsteknik

    Author : Emil Regnström; Mattias Willig; [2018]
    Keywords : Trams; sound; distance attenuation; point source; line source; sound pressure level; sound power level; sound spectrum; Oslo; Gothenburg;

    Abstract : The aim of this work was to investigate how the rate of the sound attenuation from a tram changes over distance in an open city environment, and to get a better general understanding of the tram as a sound source. By setting up an array of microphones with an internal distance of approximately 8 meters, perpendicular to the tram tracks, measurements were carried out at three different locations in Oslo as well as two in Gothenburg, and the sound attenuation was analyzed for a total of five different tram types.

  4. 4. Historisk plats, moderna problem : tre idéförslag till bullerreducerande åtgärder för Kronparken i Uppsala

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Ida Sjöberg; Matilda Weinstock; [2018]
    Keywords : buller; bullerreduktion; Kronparken; stadsnära skogsmiljö;

    Abstract : Kronparken i Uppsala huserar stora, gamla tallar med rötterna i 1600-talet. I den här skogsparken gick Linné med sina studenter och det var här han beskrev och namngav just Pinus sylvestris, tallen. Tallskogen i Kronparken har under lång tid vuxit till en mycket speciell miljö där flera ovanliga fåglar, insekter och växter trivs. READ MORE

  5. 5. Where-Else : Creating a dialogue tool to enhance green space allocation for the mitigation of noise and water runoff in urban settings.

    University essay from KTH/Strategiska hållbarhetsstudier

    Author : Elsemieke Jolien Juffer; [2018]
    Keywords : climate change; resilience; dialogue; urbanisation; water; sound.;

    Abstract : Cities around the world encounter global challenges, of which climate change is one. Urbanisation is resulting in inflexible land uses that are hard to reverse and cause fragmentation of green areas, which therefore decline in quality and contribute to the cities’ vulnerability to climate change.
