  1. 1. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Soraya Hosseinvash Azari; [2023]
    Nyckelord :Physical Geography; Ecosystem Analysis; noise simulation; traffic; Nord2000 model; building façade types; roof configurations; geospatial data; 3CIM; SoundPLAN; acoustic properties; urban areas; 3D city model; Earth and Environmental Sciences;

    Sammanfattning : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. LÄS MER

  3. 2. Road traffic noise simulations based on 3D city models

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Wenjing Liu; [2023]
    Nyckelord :3D city model; 3CIM; CNOSSOS-EU; noise simulation; city noise evaluation; data tailor; FME; SoundPLAN; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : Urban development and densification cause noise problems that can have a negative impact on human health. In 2002, the European Union (EU) stated the European Noise Directive (END) with the purpose to evaluate environmental noise levels (including the sources road, railway, and air traffic) in the member states every 5 years.

  4. 3. Lyssningsbara bullerutredningar : Auralisering av trafikbuller för bättre tolkning av ljudnivån

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Maria-Therese Carlsen; [2021]
    Nyckelord :Auralization; noise mapping; traffic noise; Auralisering; bullerkartläggning; bullerutredning; trafikbuller;

    Sammanfattning : Syftet med detta examensarbete har varit att ta fram en metod för att skapa lyssninsbart trafikbuller med datorn, så kallat auraliserat trafikbuller, att koppla till en bullerkarta. I kartan skulle det gå att lyssna på hur trafikbullret skulle låta för att ge en bättre uppfattning om vad ljudnivån och färgskalan i en traditionell bullerkartläggning betyder. LÄS MER

  5. 4. Reflected Train Noise in Swedish Noise Prediction Methods, a comparison between measurements, Nordic Prediction Method, Nord2000 rail and CNOSSOS

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Ka Hou Karl Ho; [2020]
    Nyckelord :Nord2000; NMT; Noise prediction method; sound propagation model; source model for railway noise; reflected sound; Nord2000; nordiska beräkningsmodellen för tågbuller; bullerberäkningsmodell; Ljudutbredningen modellen for tåg buller; källsmodell för tåg buller; fasadreflektioner;

    Sammanfattning : The Swedish law requires a set of noise limit for residential buildings for health and safety. Conventionally, the Nordic Prediction Method (NMT) is used to predict the noise. However Nord2000 and CNOSSOS is going to be introduced to replace NMT. LÄS MER

  7. 5. Computational sound propagation models: An analysis of the models Nord2000, CONCAWE, and ISO 9613-2 for sound propagation from a wind farm

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jôse Lorena Guimarães da Silva; [2017]
    Nyckelord :Nord2000; CONCAWE; ISO 9613-2; noise propagation; noise wind turbines.;

    Sammanfattning : The recent goals from some countries to become renewable energy based and reduce carbon dioxide emissions have caused the wind industry to grow. Together, the size of the wind farms and the noise emission have grown, while the noise emission regulations have to be fulfilled. LÄS MER
